I have an acer aspire laptop, 5742-7047. Ithas worked great until the other day when it started randomly losing power, very quick, no beeps and does not try to reboot on its own.
the only thing that was strange was it started almost exactly when i installed google sketchup, i have uninstalled sketchup, attempted a system restore which it twice denied.
My desktop had the same problem or so i thought which had turned out to be the memory, today i replaced the 4gb ddr3 with 8gb ddr3 new thinking that would solve the problem but alas no
fyi when running a memoy test prior to replacing it consistently died at aound 37% thats why i replaced the memory.
scout, the original 4 gb i removed entirely, and replaced with 8(2 simm of 4)
up-time seems to be better but still loses power with no continuity, i can just have it on without doing anything, and it just goes blank, rolled back the video driver but that doesn`t seem to have made much difference, just bought a can of air and blew the heck out of it today i`ll see if that makes a difference, shouldn`t as i have kept an eye on temps and they seem fine, this has me stumped and i`m afraid to take it to service as its intermittent
