Battery shows 100% charged when docked or plugged in using AC Adaptor. But if run alone as laptop it dies immediately.Any ideas how this would happen and does battery need replacing?To me if it neeeded replacing why would it show 100% charged?

Many battery types develop a memory effect where they end up with very little run time when fully charged.

Your options are to either buy a new battery pack, or have your battery pack rebuilt.

Run on Mains Power most of the time.

The Battery Develops a Memory and while it will charge to the correct Voltage which is all that is measured on the Battery Condition Monitor it doesn't retain the full current so that you have a very short Run Time on Battery can be as little as 10 seconds with a recharge time of under 20 seconds.

You need to replace the Battery Pack here with either a new unit or a rebuilt Unit. Depending on the make & Model of NB that you have here you may be required to have your current Battery Rebuilt and this will require handing the battery to the company and they will remove the existing batteries and replace them with new ones. If it is a common model Battery they will offer an Exchange service.

To maximize Battery Life on NB's you should regularly run on battery power to make it longer before this happens to the battery.
