and occasionally when it isnt plugged in. iv also had some issues with it running the cpu, disk, and memory at 100%, even after going and disabling bucket loads of stuff,. it wont turn on when its plugged in, and iv got to try a handful of times to get it to come on when running battery power, fan comes on, hard drive winds up, makes normal sounds. i know it isnt my power supply, iv tried others. it occasionally it throws blink codes on the caps lock led when its black screening, one blink or two blink phases. iv went into the bios and ran the tests, everything came back normal. the model is presario CQ62-211HE, AMD processor 2.2 ghz(that recently had its thermal paste redone at a shop, replaced my system fan) with 2gs ram, running windows ten home 64x. any advice would be very helpful, iv tried everything. update: tried to hook it up to my tv through vga to see if it might e a lid issue, thats not the problem.
