I have a dell studio 1555 laptop with 9-cell battery.

i wanted to ask if i am working on mains, though the battery is fully charged will it harm the life of the battery or not.

what is suitable to work on fully charged battery or through mains.

If anyone can help me with the capslock feature in the dell laptop, it will be appreciatied. i am not able to get the display of capslock on screen.

Thirdly i tried pairing my E71 nokia with the laptop through bluetooth but the laptop bluetooth is not working and giving error. even after reinstallin the bluetooth driver.

kindly help friends
 
1. If the battery is full and you are running on AC mains then there is nothing to worry. It won't harm your battery. Your battery remains idle if it's 100% charged and AC mains is ON. It will only add to weight of laptop and nothing else.

2. Working on a fully charged battery or AC mains is the same thing as said above.

3. Searching... (Meanwhile try with your quickset or similar application driver)

4. Please state the error that you are getting.
 
Its better to use the lap on battery since the continuous use on the main may drain the battery out and reduce its life, as said by the DELL cc. To get the notifications for the DELL capslock key try out the DELL Quick Set utility.

I am sorry but I didn't get you. Did you mean that using lappy with battery full charge and connected to mains will drain/reduce battery life?

AFAIK, the battery is in an idle state when it's full charged and the laptop conected to mains. So I see no harm in using AC mains as long as one wants. :) Rather, using the laptop on battery and draining the battery frequently would reduce its life and backup time as well.
 
try to use mains as much as possible because each batter has only a fixed no. of cycles it can be recharged but don't keep it on mains 100% of the time. atleast once a month use the battery until its close to empty
 
i have always used my laptop with the mains connected!!have used the battery backup for say less than 50 full charge-discharge cycles...now my battery backup is worse than pathetic 5 mins (the lap wont even boot on battery alone!!)

Have searched the net for this problem, some people think that you should remove the battery and use the laptop if you intend to keep using it on main supply for most of the time...that it would seems extend the battery life.

I would have preferred charge discharge route than the way i wasted my battery....time to buy a new battery though...guys any reco on places in banglaore???(compaq)

Which laptop are you using? The newer laptops are designed such that when your battery is fully charged and laptop connected to mains. the battery remains in idle state. In the older laptops the nickel charge used to degrade the battery however in the newer ones this is not the case. (At least this is what I know from what I have read online and heard)

Do we know this for sure?

I've always had problems with Dell's batteries. They are so cunningly manufactured that they always die out soon after your warranty would have expired :@

True ... facing same problem with my hp DV lappy...
 
I never face any such issues mention above. I till now always use on ac main on and battery connected and my battery working good and fine never need to replace or change
 
hey.... not really true, i have been in delltechsupport for years, if batery is full, u can safely work with mains, does not really affect battery life.

Negative.

If you have to work very long with AC mains it's better to remove battery. My Li On battery died because of this only, running for 24 x 7 on AC Mains with battery connected.

Can you please mention your laptop model? Older laptops had these problems but almost all the newer ones don't.
 
As far as i remember i have used my last 4 laptop with battery in and mains on and never have any issues with battery never need to replace
 
Well, you've been lucky i guess.

My Dell Inspiron 1420, purchased in July 2007, is now down to 45 mins battery runtime. (from 3 hrs.)

And i always used it on AC with the battery connected, except when i wasn't near a power source.

I've even mailed Dell asking for a quote on a replacement battery, but haven't received a response.

Does anybody know how much one would cost in the market, coz Dell original is gonna be expensive anyway.
