Toshiba:Resolving battery and power issues

Sponsored Links

It's normal for a battery to lose some amount of charge over time when the laptop is off and unplugged from power. However, some models will lose charge faster than others. A faulty battery may lose significantly more charge than a battery in good, working condition.

If a battery won't charge, if a battery can't be detected by the laptop, or if there are other power issues, there are some simple steps that can be taken. Try the following.

Power Cycle

Turn off the laptop, unplug any accessories, and unplug the power adaptor. If the battery is user-replaceable, remove it from the laptop and then hold the power button down for 30 seconds. If the battery is not user-replaceable, check the bottom for a small reset button. If one is found, press it. Afterward, reattach the battery if it was removed and reconnect the laptop.

Clean Contacts

If the battery is user-replaceable, ensure that the metal contacts of the battery and the laptop are clean.

Remove the Microsoft ACPI Compliant Control Method Battery

Remove the Microsoft ACPI Compliant Control Method Battery and allow Windows to scan your computer for hardware and reinstall the drivers needed to manage your battery's power. The notebook should then indicate that the battery is charging.

1. In Windows 8, hold the Windows key and press the 'x' key to open a menu in the lower-left, then select Device Manager. In Windows 7 or Windows Vista, click Start and type device in the search field, then select 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.

Check the AC power

Confirm that the laptop is receiving AC power. If you connect the laptop to AC power but the laptop doesn't detect it, you may need to replace the AC adaptor or seek servicing.
