Last night, my partner's laptop - the above-described Acer Aspire 5552 - suddenly stopped functioning. Earlier in the day it had started up with no problem, but when she started it up again the screen failed to display anything at all. It is not a heavily used laptop - she uses it mainly for iTunes, Facebook and email - so it seems unlikely that it would be due to overheating.
I have attempted numerous possible fixes, all to no avail. I have connected it to an alternate monitor and toggled the Fn-F5 and Fn-F6 switches to ensure the monitor was not the problem. I have removed and replaced the RAM, the HDD, the main battery and the RTC battery. I have also tried shorting the HW gap. I have tried updating the BIOS from a flash drive, but nothing happens. I've booted up using Fn-Esc, and again nothing.
I'm not sure if I'm missing some recovery software from my flash drive, or if there's something else I need to try, but my partner has a lot of family photos, music and other bits and pieces that she now can't access. Any suggestions?
