Most common current hardware problems

ViestiKirjoittaja JensenBreck » Pe Joulu 22, 2017 14:59

Hi,
The laptop turns on, power LED lights up, cooling fan works but nothing appears on the screen. The screen is completely black and blank. There is no image on the screen at all.
Possible problem:
– This can be memory failure. It’s possible one of the memory modules failed. In this case you can try reseating memory modules to make sure they are making good contact with the slot. You can try removing memory modules one by one and test the laptop with only one module installed. You can try replacing memory modules.
– If reseating/replacing memory doesn’t help, try removing the hard drive, DVD drive, modem, wireless card, keyboard, etc… In other words, disassemble the laptop to bare minimum and test again. If the laptop still doesn’t turn on, most likely you have failed motherboard or processor.

Thank you,
