Hi, I am a qualified repair technician but am not sure where to go with this one. I have a laptop in from a customer which would not charge and would not hold power. I ordered a new charger and battery (both genuine) and a DC Power Jack which was also genuine. I replaced these parts and the laptop came on but when testing I realised that it only charged for around 10 seconds and then stopped. I went through all the usual steps of reinstalling the battery and power adapter drivers and this still didn't fix the issue.
The next day when i came back to it the CPU fan had supposedly failed. I ordered a new motherboard (used but pulled from working system) and a new cpu fan, and replaced these and it went back to charging for 10 seconds then stopping again and on reboot it said again that the CPU fan had failed. This was with the NEW parts.
The only other thing I can guess at is some corruption in windows so my next test is to swap the hdd out for one of my test drives and see if it is something in windows that is causing this.
The bios is at the latest version I can find too.
Any suggestions would be greatly appreciated as I'm ready to throw this laptop in the bin haha
Thanks,
John D.
