It’s a handy little netbook, but hadn’t been used during the summer. When I switched it on yesterday – nothing happened. Battery must be flat, I thought, so plugged in the mains lead & it worked. After using it for a while, I unplugged the lead & the netbook went dead. Plugged the lead back in and restarted it, then checked on the state of the battery – it was supposedly 100% charged.
A few searches suggested the BIOS needed updating. There were other suggestions such as removing the battery, holding power on button down for 2 minutes etc. etc. but they didn’t work. So it looked like updating the BIOS. There is a page on the Acer Support site explaining what to do – and it fixed the problem, the battery is now charging again.
For anybody else with the same problem, follow the instructions on the above link.
