My gateway NV53 fails to boot up. I get a black screen. It is not back-lit, no cursor,no bios , no gateway or windows logo, and no beeping. I noticed that the clickable icons above my keyboard do not light up. Not even the hard drive icon, but when I raise the volume it does light up. I've been running off a faulty battery by just plugging the laptop in the wall. I left it on in sleep mode over night and in the morning I got the black screen. I've also been running off 1 ram stick for a while and noticed a decrease in speed over time. I think the culprit is ram stick since the same black screen happens when I remove it. Any help? Sorry for bad English
P.S Not Hdd since bios would boot saying no os
