Laptop battery (2 questions)
Hi all. I'm not sure if this should be in Electronics. I've got a Dell Inspiron 5160 laptop (3.02GHz, 256MB of RAM and a 60GB hard disk).
1. In both Dell's Quicket utility and Windows Power Management they have the option for 'Max Battery' Does this mean maximum battery life (stays on for longer, uses less power) or does it mean maximum battery power (stays on for less time, uses the full power of the battery)?
2. This is electronics bit. My computer randomly switches from AC power to battery power when it's plugged into the wall socket. It'll be using AC power for hours and then it'll just start using the battery. In order to get it back to AC power I have to follow these steps exactly:
- Unplug the plug at the back of the laptop
- Turn off the switch at the wall socket
- Unplug the plug from the wall
- Put the plug into the back of the computer
- Plug the thing back into the wall
- Turn on the wall switch
If I do anything different it'll still use the battery. This happens wheter or not I use the Dell Quicket utility.
Is this due to some faulty battery/power supply? Or is it a problem with the wiring in the walls or the wall socket perhaps? Is it some sort of power surge? Unfortunately it's the only wall socket I can use so I can't test it on other sockets.
Cheers for any help.
