Q&A - AST Laptop AC Adapter
Trouble Shooting - Is it my battery
or AST ac adapter that is not working?
Customers often buy a new battery for their laptop computers when
their laptops no longer power up. They often find themselves still
having the same problem when they receive their new battery. The
problem is usually with their AST AC adapter.
To trouble shoot, simply remove your battery and power your laptop
with the AST AC adapter only. If your laptop
powers up, the problem is most likely your battery.
