Having problems with your HP Pavilion zt1145 PC Notebook ?

Laptop intermittently works with battery

\015 Have pavilion zt1145 laptop and new battery, I have been able to get the battery to work "sometimes" (like pressing on the battery to make sure it makes good contact). I had a bad battery latch and have replaced that but still can't get the machine to work on battery. \015\012\015\012I know the battery is good, could the problem be with the AC/DC adapter? (is there some switch inside the power adapter socket that detects whether an external power adapter is attached?? if so if that "switch" was stuck in the "on" position indicating that an external power supply was attached would it prevent the laptop from using power from the battery??)\015\012\015\012Thanks\015\012\015\012Steve\015

Answers :

The adapter does not have a switch. When you plug in the adapter into the laptop a LED lights up to indicate that it is connected to the mains supply and is charging.
\015\012When you boot up the laptop with the adapter connected and check the power setting from the Control Panel and if it indicates it is on battery power, then either the adapter is faulty or the connector is not making proper electrical contact. Wriggle the connector plug to see if the charge light comes on, if it does then the loose connector needs repairing.
\015\012Replace the adapter if it is faulty.
