I had my G73jh for about 4 months now. A month ago started a weird hibertation/sleeping pattern, even on AC, and with everything turned off in Windows.
It magically worked out (or it was something microsoft broke and patch it later)
After that worked out, now I have battery charging problems. And I don't think it's my battery...
I turn on my laptop on battery and let it run for some time, let's say the battery drains till 30%, 20%, 15%, anything, pick a number. I then plug the AC and windows says it's connected and charing; but the battery is not charging. I could leave the AC plugged for an hour, 2, 3, whatever; and if I unplugged it again, it's at the same % as when I plugged it in.
It all works out if I turn the laptop off and let it charge, or if I restart windows. It's just starts charging again.
I used hwinfo32 to check the battery status, and when this problem happens, the "charge rate" it's 0.000W. If I unplug it, it goes to -66.xxxx W. I restart windows, check hwinfo32 again and it's charging at 33.xxx W
