I was just asked to take a look at this 15R-5521 computer by an acquaintance... he said he was using the computer as normal, then at some point it froze and then refused to turn back on.
What is does now is, Power light comes on, HDD light flashes twice and then everything goes off.
I tried draining residual power, reseating RAM, booting without the HDD and also booting with either just the battery and just the adapter. The only thing that produces a change in the behavior is removing both sticks of RAM, which causes it to beep twice.
Here's a video of the laptop leds when I try to turn it on:
Any ideas?
