I cannot turn on my Micro BR - its plugged in and has new batteries but still won't work Does this mean it's completely broken or is there some sort of stand by phase that may have initiated itself?


The devices that have battery AND adapter capability OFTEN have a switch that the adapter opens when powered by the adapter. Often this switch contact gets bent and units won
t run on battery, so try it on an adapter... if the adapter works and battery doesn't, this contact whcih is a part of the input power connector has failed.

Dell latitude 610 AC adapter issue or battery pack issue or both?


It could possibly be the power jack that is inside the computer. This item is typically soldered onto the motherboard and it is what your ac adapter plugs into.

Not charging batteries


It sounds like you are using a 65 watt AC adapter or an Auto Air Adapter.
The system needs a 90 watt adapter to charge the battery while the system is on.

My Compaq Pres V2000 laptop does not get on with power on switch


Take out the battery and only hook up the AC Adapter to see if the laptop turns on. If it does then you know the battery is shorting out the laptop and either has very little power to turn on the laptop or is shorting out the laptop cause its bad.

If you don't get the laptop to turn on, make sure your using a well known working wall outlet to plug the laptop to and only use the AC Adapter. If you AC Adapter is hooked up and the Green Led turns on then you know the adapter is good.

After those two steps, you can also try taking out the dvd drive and the hard drive. Then try turning on the laptop and if the laptop still doesn't turn on then the motherboard is bad in the laptop.

Laptop intermittently works with battery


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.
When 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.
Replace the adapter if it is faulty.
