At least we're looking at the right computer now. Thanks for that. However, I'm trying to replace the bios battery, not the main battery. The error is something like "replace bios battery".
Here is a video on how to take apart the E205 model. https://www.youtube.com/watch?v=psR6qf9_66A
The battery is located on the underside of the motherboard it should look like a metallic coin battery. Like a good sized watch battery you should know it when you see it.I hope that helps.
Cann't see it. Can you find a picture of the board showing it?
Unable to see battery, on top or bottom. Can you find the board manufacturer and part number?
Your info did not resolve my issue. I ended up reseting my BIOS time
and restoring my system from backup. It's currently working but I'm expecting the bad BIOS battery again since I didn't replace it. Since Toshiba has the error I would expect them to have a solution for the message, but I've been unable to fine it.
