Hi ,

I HAVE Acer 4920

Q1. If I remove the battery then, Can I run the laptop directly on power source ?
Q2. IF Yes, will it damage laptop in any way ?

My Grandaughters Laptop battery has not worked for a while as it is over five years old. You just have to be careful not to lose the mains supply while you are active.

Better to run with the battery in and unplug the mains and run it down with the battery once a month to keep the battery ticking over. Some say keeping it plugged in all the time reduces the longevity and charge capacity, I'm not so sure but I use the above method just in case.

I have recently taken posession of a new company laptop. I asked a similar question i.e. how long should I run the machine on battery alone? The I.T. consultant told me to never run it on battery unless absolutely necessary. Just keep it on mains. This particular laptop is switched on for around 12 hours each day. I don't yet know if this will have any long term effects.

I have heard that running a laptop with the battery always connected and the laptop plugged into the mains can seriously reduce the battery life. Basically just run the laptop on battery when you need to and unless the battery requires a charge, disconnect the battery from the laptop when you plug it into the mains supply.
