the buttons to press to reset a Toshiba laptop when the lithium battery can’t be removed easily

Sometimes a laptop goes into a comatose state that no amount of charging or on-offing can end. The solution might be to try the following. If you’re desperate do them all – but then you’ll not know which trick worked.

Try one of the following (listed in order) and see if that fixes it

1. Disconnect the power supply and if there is one, disconnect an easily removable battery for a few moments.
2. If you can find a reset ‘button’ on the laptop casing, push the end of a paperclip into a reset hole – but don’t push an LED hole!
3. Hold the power button down for 20 seconds
4. Power the device. When the laptop restarts go to Device Manager > Batteries > Uninstall the ACPI battery. Restart the device.

Some Toshibas such as the Toshiba Portege Z830 / Z930 or Satellite U840 / U940 have neither a reset hole nor a removable battery. Until I discovered the following method, I used to remove 13 base panel screws and the metal panel and then disconnect the battery connector for a minute. That’s half an hour’s work the first time you do it (see below). Here’s an alternative:

• Disconnect the power supply. Hold the power button AND the presentation button down for 20 seconds
• Power the device. When the laptop restarts go to Device Manager > Batteries > Uninstall the ACPI battery. Restart the device.

Alternative, very long way to reset the Toshiba laptop (eg Z830 / Z930) or replace its battery

There’s no need to remove the battery to do the reset above – but do know that the battery on this model is replaceable. I replaced my battery with a cheaper third-party battery which later failed due perhaps to leaving it on-charge). The video below shows how to remove the central base screw plus the 13 or so screws around the edge of the base. When you are sure that all the screws are out, slide the shell base to the right to ease it off the 3.5mm sockets, leaving you looking at the laptop insides. Disconnect the battery plug for some seconds. To replace the lower case shell, first get the 3.5mm sockets in the shell holes.
