The "Plugged in, Not Charging" issue is fairly common..
Uninstalling and reinstalling power management software in Windows Vista/Windows 7
In order to correct problems with the battery's power management software, follow the steps below.
1. Access the "Device Manager" .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall.
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. Restarting Windows will have the same effect of letting Windows re-recognize the hardware and installing the correct drivers.
If that doesn't fix it, then shut down the computer, unplug all power cords, remove the battery, then depress the power button for 30 seconds. Replace the battery making sure all connections are solid, then plug in the power cord. Hopefully things are good.
Hope this helps.
Hi, I got an acer aspire 7741z-4433 laptop about 2 months ago. Has windows 7 preloaded. Was on road trip this last weekend and was using laptop in vehicle on battery power. It gave me the warning to switch over to ac power or all would be lost... as I was just playing mahjongg I didnt care and I let it die on me. Ever since then my battery will not charge at all. Mousing over the battery icon on bottom right at says 0% available (plugged in,not charging) If I remove battery with the laptop plugged into ac power it cotinues to run but the icon develops a little "x" on it and indicates battery missing (plugging batt back in makes to go back to previous state). If I pull ac power the laptop dies within 30 seconds.The terminals for charging the batt are clean and show no signs of damage or arcing as is the female part on the battery. Shutting down the comp and plugging it into ac does not force a charge either....any ideas?
