Advent Monza T100 Won't power up using AC adaptor alone (battery light flashes red).Insert the battery press power button and starts ok but battery not charging. I then remove battery(to save charge which is at 90%) and laptop works fine by AC Adaptor alone. Same thing happens using another ac adaptor. any suggestions?
 
Welcome to Tom's Hardware Forums!

It's good that you tried a second adapter. A few things to consider:

1. It is possible that the laptop is designed to startup only with the battery in place. The manual can provide clarifications.

2. Maybe the battery is charging but the indicator light is defective.

3. The charging circuit inside the laptop is bad.
