Reflow - Full Guide

*** Friendly note : Please wear anti-static wrist strap when you work with laptop/electronic component, because electrostatic will damage your laptop permanently.***

This guide is for you if your laptop still alive with LED light on but no Display = Black Screen

Dear readers,
Especially to those laptop users who experienced this problem (Black Screen = GPU Failure -one of the reason). What you should know is, every laptop are using built-in GPU. In simple word, the Graphic Card is attached to your laptop motherboard directly and can't be separate by any human (unless you use violence ??? ).

Why GPU failing??? Ok, the explanation is here. Earlier, I said your GPU is attached to your motherboard and can't be separated by any means. So it means something must be putting them together. The glue in electronic world is the solder.

Now we know about the solder. For your information, everything have its specific melting point. For this solder, the melting point is about 150 - 200 degree celcius. Check this out to know other solder melting point.
The melting point is low because of the use of tin based solder. It's cheaper than the other thats why they use it to attach a GPU to the motherboard and also attach other component to the motherboard such as capacitor.

Let us understand the condition of the solder on the motherboard. Let say you put an ICE cube on a plate, and heat it. It will melt right. If you cool it down to its freezing point, it will freeze again but lets observe its shape? does the shape of the ice cube same as before it melt? No right? So, basically, the same thing happen to the solder on your motherboard. Sometimes the heat exceed the melting point of the solder, so it will melt. But, when it cooldown and freeze, the shape maybe different. Maybe have tiny cracks that invisible to your eyes has occur. *** Even a tiny crack on the solder can make your laptop malfunction ***

Laptop Black Screen - Hardware Faulty

*** Friendly note : Please wear anti-static wrist strap when you work with laptop component, because electrostatic will damage your laptop permanently.***

Hello guys,

I will guide your through this problem. Now we assuming there is hardware faulty.

Cause :

1) Due to constant opening and closing the lid, your screen cable maybe damaged.

2) The connector might loose.

Where is the place of these connection???

Above keyboard, under your laptop speaker, and runs by the side of the screen hinge up to the back of the screen and connect at the top.


Before we get started, you should know the following :
Basically, the cable runs between the base of the laptop and the back of the screen and there are about thirty tiny wires wrapped up with tape. When I took my laptop to bits I removed this cable and re attached x4 broken wires using additional super fine wire ply and tape. The ideal would be to solder the new wire. My tip is to burn away the wire casing using a match/ cigarette lighter very briefly then rub off the plastic to expose the wire using finger and thumb.

*** If you don't have the skill level to repair broken wires then simply buy a new screen cable, when you open the laptop up there is a code under sticker on the cable. You can buy them from any good HP spare parts retailer ***

Know how to remove the damage cable? If not, please follow the instruction below :

1. Remove the battery and power cable.

2. Remove all the rubber pads from the inside of the screen to expose screws (x5) -Please don't unscrew!

3. Tip the laptop over and remove x6 sliver screws from within the battery compartment. (These screws hold on the speaker cover above the keyboard that also houses the quickplay buttons volume and power button)

4. Very carefully using a flat blade screwdriver prise off the speaker cover around the left and right hand side of notebook. DO NOT PULL COMPLETELY OFF THIS COVER UNTIL YOU UNPLUG THE ATTACHED QUICKPLAY WIRE !!!

 5. Once this speaker cover is completely removed then you will see x2 hinge covers that are kept in place with a screw on each. Remove each of the screws then gently prise off the hinge covers being very careful not to disturb the wires that run around them.

6. Next is to remove the inner screen cover surround. All the screws should already be exposed, remove them all now and them very carefully prise the casing off using a flat blade screwdriver.

7. At this point you will now see additional screws attaching the lcd screen to its mounting plate X3 at each bottom corner and x2 at the top. Remove all of these screws and this will allow access to the back of the lcd screen.

8. You now need to remove the cable which should be in plain view front and back. Firstly disconnect from above the keyboard using a screwdriver to gently prise off the clip. Next remove the plug from the inverter (a long strip of circuit board that runs at the bottom on the screen. Only disconnect the left hand end that connects to the screen cable. Once these two have been released, go around the back of the screen (helps to gently move the screen hinge forward for this bit. Remove the celloptape that holds the bottom of the cable in place, then remove the plug at the top of the screen by firsly removing the holding tape. Be very gently and pull out using both hands gently wriggly out the socket.

*** Friendly note : Please wear anti-static wrist strap when you work with laptop component, because electrostatic will damage your laptop permanently.***

At this point the cable should be free and can be gently removed from the note book for either repair or replacement. Repair is quite simple if you are handy with electronics but beware, the cables inside the black tape wrap are very very small. It is delicate work. If you can't fix then replace by quoting the code number on the cable sticker.

Refitting is the opposite of the removal, just remember to be very careful with the cable placement and when starting to open and close the lid again, do it very slowly the first time to ensure no part of the cable is trapped.


THE JOB IS DONE !!!! HAPPY DAYS.

How to check Streamyx SNR Margin and Line Attenuation reading?

Firstly, what you need to know is the measurement and what is the meaning of each number you see. Refer below.

How to know which interval is good???
For SNR Margin:
 
If your SNR reading is equal or less than 6dB
- bad connection/frequent disconnections(Disconnected in 1-5 minutes) or can't connect at all
 
If your SNR reading is between 7dB - 10dB
-Consider average connection but still have disconnection issue
 
If your SNR reading is between 11dB - 20dB
-Good connection with no connectivity problem
 
If your SNR reading is between 21dB - 28dB
-Excellent line quality
 
If your SNR reading is greater or equal to 29dB
-Fantastic, never worry about anything!



For me, 11dB-13dB is good enough and you can already connect to the internet without disconnection issue/problem because my house distance is greater than 5KM from the nearest TM. *** For you to achieve SNR reading above 20dB, your house distance from the exchange point(Nearest TM) must be less than 5KM.*** 


There's one more thing about Streamyx Line, that is the Line Attenuation, below is the interval guide line (Basically, Line Attenuation is opposite to SNR margin value) :


For Line attenuation:
Greater than 60dB
-Bad Line Quality
 
Between 50dB - 60dB 
-Acceptable
 
Between 40dB - 50dB
-Good
 
Between 30dB - 39dB
-Great
 
Between 20dB - 29dB
-Excellent
 
Less than 20db (your house must be very near with TM)
-Fantastic!



How to check this information ???
1) First, make sure you connected to your Riger Modem(wired/wireless). 

2) Open your browser and on the address bar, write " 192.168.1.1" without the quote and press enter.
*** Note that the192.168.1.1 is common ip address for Riger modem or any modem for streamyx ***

3) You should see the login page. Now fill the Username and Password Field. "Username : tmadmin ; Password : tmadmin"

4) Now, you should be seeing your modem information. Don't change anything, just browse through every tab. Because different Modem will store the Line Attenuation and SNR Margin in different tabs. 
*** Note : Please make sure that you are connected to the internet, if not, the SNR Margin and Line Attenuation field will be blank. ***


5) Compare your modem reading with the information I give earlier.

Streamyx Problem - Frequent Disconnection

Hi guys,

First ISSUE

I know that this problem is a pain in the ass problem, because I already experienced this. When I apply for Streamyx for the first time, they give me a wired modem ( I need to use LAN wire to connect my laptop and PC to the modem ).
For your information, the modem TM contractor gave to me was Riger.

Here's my problem for the first modem.

*** Friendly Reminder : Please check that there's no other telephone in your house connecting to your house wall socket as i know some house have more than 1 telephone wall socket. Streamyx modem can't connect to the internet if there's other devices(telephone) connected in parallel with it. all telephone must be connected from the splitter *** 

I have frequent disconnection issue. When I say the word frequent, I mean my internet connection was never be able to connect and stay stable for more than 30 second, sometimes maximum connection time is 5 minutes. This happen during daytime(As people says the telephone cable(on the pole) is getting longer during daytime because of the heat from the sun(Physic). So, this may decrease your SNR (Signal to noise Ratio) and increase you Line Attenuation reading.

Click HERE to learn how to see your SNR Margin and Line Attenuation reading.

For a Streamyx user who encounter this problem,
Here what I do,

1) I try to bypass the splitter and connect my modem directly to my house wall socket. ( Splitter is the small rectangle box which connecting your Home Telephone and your modem )
See image below :

Step 1 worked for me as the SNR Margin increase and no more disconnection occur. So I know my splitter is the problem and I change with a new one(try to find splitter with high quality).

2)  Try to change your Telephone jet(small cable connecting your modem to the splitter and wall socket. If still doesn't solve your issue,

3) Check if your house wiring more than 5 years, it also may cause you a problem.(your wire may be damage by weather or other causes). Change a new cable from the Telephone Pole to your house and change also your wall socket.

4) If the above steps doesn't solve, call 100, or directly call the TM technician(FOC) not the contractor as they will charge you. If you want them to work fast, call and remind them everyday.

Second ISSUE

This happen when I change my MODEM to a WIRELESS RIGER Modem from a Wired Modem. It may sound silly, but this is what happen to me. I thought there'll be no more disconnection issue because I already solve my disconnection ISSUE while I'm using the wired modem.

BUT,
After I change my MODEM to a wireless modem, I can't have a stable connection at DAYTIME starting at 8a.m until 7p.m and I always get disconnected from the internet within 30 second or maximum 5 minute after i connected to the internet.

SEE my SNR Reading at daytime.

Funny thing is, after 7p.m daily, I have no disconnection issue. (Means that I can conclude that the source of the disconnection problem is not from my wiring, telephone jet) because at night the connection was great.

So, how i solve my second issue,
1) I call 100 and speak to TM Staff. Make sure you mention all steps you already make like in my FIRST ISSUE. Because, they will ask you to do the same thing.

2) Let them know your SNR Reading and Line Attenuation Reading.

3) Sometimes they will reset your port from their office. They'll ask you to restart your modem. (This doesn't solve my problem).

4) Lastly, I ask them to send their Technician to go to my house and check the necessary thing. I call them daily. So they send a Technician only about 3 working days. The Technician climb on the Telephone pole and do something (I don't know what) but after that, the connection was splendid and MY PROBLEM SOLVED!!! Never have a disconnection issue again even though my house distance from the exchange point is more than 5KM.

Please take the Handphone number of the technician as you can save your time to call them instead of calling the 100.

The fastest way is to ask the technician to come but TM have their way of doing things, must go trough this first and then that and that... Never ending protocol.

How to Reset an IBM ThinkPad Laptop Password?

Good day dear readers,
For you information, an IBM ThinkPad laptop can have three hardware password sets:

• Power-On Password
• Hard Disk Password
• Supervisor Password

Power-On Password

RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if a power-on password is installed, the password bytes are locked and no program can access them.
During power-on password installation, the password (1 to 7 characters) is stored in the security space.
Installing the password is a function of the built-in system program Easy-Setup. The power-on password does not appear on the screen when it is installed, changed, or removed. After the power-on password has been installed, it can be changed or removed only during POST.

Hard Disk Password

The hard-disk password (HDP) prevents unauthorized persons from accessing the data on the removable hard disk drive.

Supervisor Password

The supervisor password prevents unauthorized persons from changing the system information in Easy-Setup.

How to Reset an IBM ThinkPad Power On Password using Software

If the user can boot the IBM ThinkPad, KeyMaker will recover the BIOS password.

How to Reset an IBM ThinkPad Power On Password Using Hardware

If the ThinkPad cannot be booted, reset the IBM ThinkPad password via hardware.
If only the power-on password is set, do the following to remove the power-on password.

1. Power off the computer

Recover Laptop BIOS Password

Good day everybody,

The best method for resetting a BIOS password depends on what BIOS the computer has. Common BIOSs include AMI, Award, IBM, and Phoenix. Numerous other BIOSs exist, but these are the most common.

Some BIOSs allow the user to require a password before the system will boot or before the BIOS setup may be accessed.
The general solution categories to reset a BIOS password are:

• Using a Backdoor BIOS Password
• Resetting the BIOS Password using Software
• Resetting the BIOS Password using Hardware
• Vendor Specific Solutions for resetting the BIOS Password

Using a Backdoor BIOS Password

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works no matter what the BIOS password is set to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords

Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.

Award Backdoor BIOS Passwords

One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.

Phoenix Backdoor BIOS Passwords

Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.

Backdoor BIOS Passwords from Other Manufacturers

Reported BIOS backdoor passwords for other manufacturers include:

Manufacturer	BIOS Password
VOBIS & IBM	merlin
Dell	Dell
Biostar	Biostar
Compaq	Compaq
Enox	xo11nE
Epox	central
Freetech	Posterie
IWill	iwill
Jetway	spooml
Packard Bell	bell9
QDI	QDI
Siemens	SKY_FOX
SOYO	SY_MB
TMC	BIGO
Toshiba	Toshiba

Remember that the passwords listed may not be the actual backdoor BIOS passwords. These backdoor BIOS passwords may simply have the same checksum as the real ones. For Award BIOS, this checksum is stored at F000:EC60.

Resetting the BIOS Password with Software

Every system must store the BIOS password information somewhere. If the user can access the machine after it has been booted successfully, he/she may be able to view the BIOS password. He/she must know the memory address where the BIOS password is stored and the format in which the BIOS password is stored or have a program that knows these things.
Users can write their own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that they wish to read in port 0×370, then reading port 0×371′s contents.
!BIOS recovers the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc., Award, and Phoenix.
CmosPwd recovers the BIOS password for the following BIOS versions:

• ACER/IBM BIOS
• AMI BIOS
• AMI WinBIOS 2.5
• Award 4.5x/4.6x/6.0
• Compaq (1992)
• Compaq (New version)
• IBM (PS/2, Activa, Thinkpad)
• Packard Bell
• Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
• Phoenix 4 release 6 (User)
• Gateway Solo – Phoenix 4.0 release 6
• Toshiba
• Zenith AMI

Resetting the BIOS Password via Hardware

If a user cannot access the machine after it has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that a small battery maintains while the PC is off, which is attached to the motherboard. If the user removes this battery, all CMOS information (including the BIOS password) will be lost. The user must re-enter the correct CMOS setup information to use the machine. The machine’s owner or user will most likely be alarmed when he/she discovers that the BIOS password has been deleted.

The battery is soldered to some motherboards, making it difficult to remove. If this is the case, there is another alternative. Somewhere on the motherboard is a jumper that will clear the BIOS password. If the user has the motherboard documentation, he/she will know where that jumper is. If not, the jumper may be labeled on the motherboard. If neither of these is the case, try guessing which jumper is the correct one. This jumper is usually standing alone near the battery. If the user cannot locate the jumper, he/she might short both of the points where the battery connects to the motherboard.
If all else fails, clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on the motherboard.
Many RTCs require an external battery. If so, clear the BIOS password by removing the RTC from the socket and reseating it.
RTCs that require external batteries include:

• Dallas Semiconductor DS12885S
• TI benchmarq bq3258S
• Motorola MC146818AP
• Hitachi HD146818AP
• Samsung KS82C6818A

Most RTC chips with integrated batteries can be reset to clear the BIOS password by shorting two pins together for a few seconds.
There are a few options for some chips due to the testing that various people in the field have carried out. Remember to remove power from the system before shorting these pins.

RTC Chip	Pins
Dallas DS1287ATI benchmarq bp3287AMT	3 (N.C.) and 21 (NC/RCL)
Chips & Technologies P82C206	12 (GND) and 32 (5V)-or-74 (GND) and 75 (5V)
OPTi F82C206	3 and 26
Dallas Semiconductor DS12887A	3 (N.C.) and 21 (RCLR)

Users should be able to figure out how to reset the BIOS password stored in most RTC (Real Time Clock) chips by reading the manufacturers data sheet for that RTC. Some RTCs, like the Dallas DS1287 and TI benchmarq bq3287mt, cannot be cleared. The solution for resetting the BIOS password on systems with those RTCs is to purchase a replacement RTC chip.

Forgot BIOS Password - PC

Hi guys, for those who own a PC and forgot their BIOS Password( if u set ), here are the solution and hopefully it works for you :

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

*** Friendly Reminder : Please turn off your PC and unplug your power cable from the socket before you do STEP A. This step require you to open your PC CPU Casing, please equip yourself with proper tools ***

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully.  There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.


B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

# Protect your online privacy and browse the web anonymous by changing your IP with Hide My IP.

Where are these fake IP addresses located? Hide My IP selects a random IP from a list of hundreds of anonymous fake IPs from all over the world. The chosen IP is then automatically installed into your web browser, e-mail client, game, or other application you specify Hide My IP to work with, allowing you to surf the Internet and use Internet-based software while remaining totally anonymous.

Windows Media Player is not responding

Problem : 
Its freezes the computer up so bad until you have to manually power down because it says "not responding".

Laptop Model : CQ62-219WM

Operating System : Windows 7 home premium 64-bit

Solution :

It may be worth trying to reset Windows Media Player as follows.

Click the Start Menu and select Control Panel.  Open Programs and Features, Click 'Turn Windows features on or off', open up Media Features and "untick" Windows Media Player.  Click Yes then OK and then restart the notebook.

When Windows has restarted, click the Start Menu and select Control Panel.  Open Programs and Features, Click 'Turn Windows features on or off', open up Media Features and "tick" Windows Media Player.  Click Yes then OK and when WMP has finished installing, restart the notebook again.

Next, carry out the following process to force Windows Media Player to re-build the Library Database.

A useful utility for viewing all the files on your PC is called Free Commander, on the link below, as it displays folders that the Operating System normally hides and has a good search function.

http://www.snapfiles.com/php/download.php?id=107872&a=7122339&tag=601108&loc=10

This is a zipped file.  If you don't have an extraction utility installed, download and install 7-Zip which can be used to open this so that you can run the installer.

Make sure Windows Media Player and Windows Media Centre are closed.

Launch Free Commander, double click Users, double click 'your user name', double click Local Settings, double click Application Data, double click Microsoft and double click Media Player.  Delete all the files that have the extension .wmdb - do not delete any folders.

Close Free Commander and open Windows Media Player - it will now begin to re-build the library database which may take a while.

DVD/CD-ROM device driver corrupted ( HP Laptop)

I'm not sure if the solution can be used on other brand of laptop with the same problem, but if someone do try, please comment to let us know. :)
 
Note : 
This solution is taken from http://h30434.www3.hp.com/t5/Notebook-Hardware/DVD-CD-ROM-device-driver-corrupted and hopefully it can solve your issue.

Question 1 :
 
I have a HP Pavilion dv6853cl notebook, Vista (64-bit). The DVD drive is listed in Device Manager as Slimtype DVD A DS8A1H ATA Device and reports "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Is there a way to download a new/updated driver or a registry update for this device that will resolve this problem?

Solution : 

Optical drives do not need drivers as such to be seen in the device manager....they are activated by the OS at a very low level. But XP and Vista are prone to occasionally losing them and you need to do a registry hack involving removal of the upper and lower filters. Here is the info you need:

UPDATE
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}
Apparently it seems that this is an age old fix for even XP systems. If you venture to the registry key above by doing the following steps:

1. Click on the start menu.
2. If this is a Vista machine in the search box type in “regedit” without the quotation marks.
3. Maximize the HKLM and then go ahead and browse until you reach the key listed above.
4. In the right panel you’ll see something along the lines of “UpperFilter” and “LowerFilter” you want to click on each “filter” key and hit delete. Click yes when it asks to confirm if you wish to delete the key.
5. Restart Windows.

Question 2 :

I am having trouble with a CD - Rom driver on my HP laptop.  Specifically, I am dealing with a Slimtype DVD A DS8AZH ATA device.  It has been giving me trouble for some time, I even returned the computer to HP, got the mobo replaced, and it is still giving me problems.  After uninstalling the device and restarting the computer, I get an error prompt stating:

'Device driver software was not succesfully installed'
Please consult with your device manufacturer for assistance getting this device installed.

 I do not to send my computer off for another three weeks, espcially if HP isnt going to fix my problem.  Can anyone please help me or at least point me in the right direction? 

Thanks a bunch!

Solution :  


code 39 means that the filters for the DVD rom drive have become comprimised. You must have installed some type of burning software. you need to make a registry edit.

WARNING: EDITING THE REGISTRY MAY CAUSE UNDESIRABLE AFFECTS ON YOUR SYSTEM. FOLLOW THESE STEPS EXACTLY AS SHOWN

1)Click start
2)type "regedit" without the quotes
3)above in the programs list right click on regedit and click "run as administrator"
4)click file and click save to make a backup of the registry incase you mess up
5) go to this path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
 6)click on the file that states 4D36E965-E325-11CE-BFC1-08002BE10318 and look at the right hand side
7)right click and remove anything that says "upper filters" and/or "lower filters"
8)close out of registry editor and restart the notebook
9)Your issue should be resolved

Your burning software will need to be reinstalled.
