Hi,
I have an acer aspire 5 a515-51 that turns on but has a black screen.
This laptop has the same symptoms as https://www.badcaps.net/forum/showth...er+aspire+a515, however mine is a different model Acer Aspire A515-51 (without the 'G'). There is no onboard ram on this laptop.
Description of the problem is the same: I press the power button, the fan spins for a few seconds and then stops, the computer stays on all the time (led blue), the cpu and gpu are lukewarm. If I leave the pc on for a few minutes the fan starts spinning a bit and then shuts down again and the pc stays on all the time.
motherboard: LA-E891P
C5V01 REV 1A
I have tried an external keyboard and although all of the lights on the keyboard flash once when I press the laptop power button, there is no response from the keyboard once the laptop is on. So I can't make the caps lock key illuminate and ctrl-alt-del does nothing.
Some history: bought faulty with intention to fix but laptop was originally booting into Windows. However, there was always an underlying problem as the laptop would often blue screen as soon as Windows started. Sometimes the laptop would stay on longer but would become unresponsive on a black screen.
I did a memtest on the ram stick that was inside the laptop and it failed with many errors. I did try cleaning the ram contacts wih alcohol and then it no longer showed any errors in memtest.
On the last time the laptop booted it blue screened giving the "Irql_not_less_or_equal" message. Upon restarting the laptop it was stuck power cycling. Once I changed the ram the laptop no longer power cycled but would no longer post either.
Note: I had also seen the "Paged_fault_in_non_paged_area" message in previous blue screen crashes.
I would like to be able to locate the fault but I am new to board repair so might need things explaining.
Many thanks in advance
