I unplugged the video cable from the system board and the laptop started fine again with the external monitor. So, the only part that I added before it failed was the LCD screen assembly. The laptop failed to boot again with the same symptoms. After I assembled everything back, one more surprise was waiting for me.
Just in case I restarted it 3-4 times and each time I got video on the screen. I opened up the laptop case, removed the LCD screen assembly and reseated the video card and… Surprise, surprise, the laptop started fine with an external monitor attached.
Nothing helped to start the laptop normally. I tried to power it on for a few times with the same result.įirst of all I tried simple stuff: remove the battery and start the laptop with AC adapter plugged in, reseat and swap the memory module, remove the hard drive, the DVD drive, the wireless card. After I pushed on the power button, fans started spinning and were active for a few seconds and laptop just turned itself off. I plugged the AC adapter and tried to turn on the laptop.
