Hp dv9207us laptop motherboard troubleshooting

I have dv9207us laptop with me. it was suddenly dead. normaly i don't shutdown the laptop, same thing i did one night (just simply folded the screen it went to sleep mode) and opened the screen on the morning, it was totaly dead and some smoke smell has come and did the basic testing with these components (outlet, A/C adaptor, removed the battery) all are perfect, Then i have removed the battery and connected my laptop with the adaptor only...hmmm no use. No display. then I decided there is something wrong with the motherboard.

I have disasambled the laptop with the HP Service Manual. I have sperated the motherboard.

Now How to check the motherboard is the problem? I tried connecting just the motherboard with keyboard + powerboard and powered UP, but nothing was happening (no LEDs were blinking)I thought atleast if the CPU FAN run's then I can continue something.

Can I order the same motherboard and replace? please help me ...

    It is possible that some other component may have an effect on the motherboard you install.
    But when you are buying used parts or replacing new parts with used parts ,it is alway's a risk.

Hp compaq 6737s not powering up


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Sudden shutdown


If the battery is full and still shuts down suddenly then it could be a heatsinking problem on your Notebook. Also try unchecking the option "Automatically Restart" from StartUp & Recovery section in System Properties.

It sounds like a malware that corrupted the system. Try booting into safe mode. That way it runs a very reduced amount of programs and processes so that it won't run into that error you are receiving. In safe mode, you can scan your system for malwares. Once your machine is clean, and the error still persists, it could be a disk error that the malwares left behind. So run the disk checking utility. If the problem still persists after that, then you'll need to do a repair (partial) install of the OS by booting from the Windows disc. That last option is also valid if you cannot boot to safe mode. If any of my suggestions work, please do rate me. Thanks and good luck. Hope it all goes well for you.

For solving blue screen error


HP Notebook PCs - "Windows Unsafe or Sudden Shutdown" Blue Screen Error Occurs During Startup or Boot

Description
Windows XP may not start and the following error message may appear on a blue screen:
Windows Unsafe or Sudden Shutdown
This error occurs after Windows was not shutdown using a safe method. The notebook may have been turned off without clicking Shut Down or briefly pressing the computers Power button. The power may have been suddenly disconnected from the computer or the Power button may have been held for more than 5 seconds.
An unsafe shutdown can damage some of the Windows system files, preventing the computer from starting properly.
Solution
If the error occurs allow the operating system to complete a check of the hard disk. Windows will prompt your to run CHKDSK. CHKDSK scans the hard drive for damaged files and repairs the files if necessary. The scan may take up to an hour depending on the size of the hard drive and the number of damaged files. The computer will restart when the scan is complete and Windows should start normally.
If Windows will not start or the computer will not boot after the scan is complete see: HP Notebook PCs - Troubleshooting a Startup or No Boot Problem (In English)
