PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version: Windows XP
Problem Application Name & Version: N/A
Problem Hardware Make & Model: Advent 7011 Laptop Standard battery
Error Messages:



The battery on my laptop only lasts about 5 mins, when i use it un plugged. I use it as a desktop computer so it is plugged in all the time. Someone said i should discharge it first (using a 12v lamp or similar) then charge it for 24 hrs. Will this help. And should i unplug the charger when the laptop is off?

Thanks

I tried doing this 4 times, and it hasnt really helped. It seems as the battery stops charging after only a short time (the charging light goes out)

You asked for it!

 Nickel Cadmium (NiCad). As the oldest of the four technologies, nickel cadmium batteries are
rarely used in portable systems today as main power (some use NiCad for standby batteries)
because of their shorter life and sensitivity to improper charging and discharging. The life of the
battery

Hi,

You will not damage your battery by letting the battery discharge completely in the laptop.

How old is the battery?

Perhaps it does need to be replaced.

Hi,

I assume the laptop is still under warranty. Bring it back to where you purchased it from and let them know you did 4 discharged/recharge cycle and that the battery is still not keeping its charge.

Make a backup of your important files in case you have to leave the laptop with them.
