2...........Hold down the "FN" key and turn the unit on with the main sliding Power switch and immediately start to tap the "F11" key.
3.............The unit will look likes it's shutting down. Let it do this three times.
This resets the CMOS. On first boot, the POST will check the RAM and
inform you that changes have been made. Accept the changes. This also
resets all of the information in the BIOS to the defaults. If you have
made changes (security passwords, asset numbers,etc.) enter
the BIOS first and record all these settings so you can restore them

are the inside of the battery terms dirty,corroided? do you know if motor alt is charging batt? how long did it run when you put new batt in? if it lasted about two days, its proubly not charging, also make sure nothing is being left on draining batt down, to check that, leave batt nuhooked pos side over night.
If the recharageable battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.
Since you are having a new battery and alternator the charging circuit of the electronic charging unit is a possible suspect.
All what is required is to check the charging voltage when the engine is started, if there is no increment of voltage when the engine runs the alternator then the connection from the alternator must be checked. Check the output from alternator, check the relay box which contains the charging unit. It can be a failure of the rectification or the stabilising circuit, the unit must be replaced.
This error is commonly seen in Compaq laptops.
Take out the battery,start the laptop with the adapter only and see if that error message pops up again and if not then it might be your battery.Usually battery life is 3yrs.
Put the battery back again and see if the message pops up again.
Try the battery on a different laptop.
It could be the Voltage Converter Board...see service manual for the same or call Compaq service centre.
The problem with your system is that the Battery you are using is Faulty is either the current voltage spoilt it or may be is an old age battery
What you will have to do is to get another Battery that you will first of all Charge it well before usage ok. nice
