I have a battery that is a bit messed up and probably needs to be replaced. In the meantime, I would to use it without it automatically going into sleep mode. Sometimes this happens after about 20 minutes, without any warnings. It doesn't seem to matter at what level I put the alarms. After about 5 minutes of being plugged in again, the battery seems fully charged.
This is with Windows 7. When I using XP, I could turn off the battery critical event handler all together, and just use the laptop until the power literally ran out. Yes, it's like a crash and requires a reboot, but if you are expecting it, not the bad at all actually, especially to maximize the usuge of your PC when on battery.
Is there a way to do this on Windows 7 or 8?
P.S. My laptop also has an overheating problem, and the issues may be related, however, I don't know which came first. I may make another post on the overheating. But basics of preventing overheating have been applied.
