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

Sometimes a laptop goes into a comatose state that no amount of charging or on-offing can end. If the laptop has a removable battery the solution might be to

  • Disconnect the power supply and unclip the battery.
  • If you can find one on the laptop casing, push the reset button – do this by pushing the end of a paperclip into a reset hole (not an LED hole!)
  • Hold the power button down for 20 seconds
  • 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, I’d remove the bottom panel screws and the 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

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 sure 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. There’s no need to remove the battery. To replace the lower case shell, first get the 3.5mm sockets in the shell holes.
