260495 2004-08-11 09:29:00 Until now a laptop has been my only computer. I now have a desktop and will use the laptop for backups and the occasional trip away.

Is it better to:

1. Unplug the battery and use power

or

2. Keep charging and discharging the battery regularly

260496 2004-08-11 09:39:00 if you are mostly going to have the lpatop hooked up to mains power, do not leave the battery in, we made this mistake and within 6 months the battery was absolutely stuffed it would not hold a charge lagbort (5041)
260497 2004-08-11 12:27:00 Hi.
I've had my Toshiba notebook for 5 mths now.

Was warned by the shop that sold it to me that if I did not use the battery at least once a week and use it up completely, ie till computer warns you to switch to normal power, then the battery would lose its ability to charge up fully again. And if I wasn't going to do that, then to take it out.

I think they can only be recharged so many times anyway.

I'm too lazy to pull it out. We often get powercuts here in Winter and I figured it would be handy left in. But I do make sure that battery is discharged completely at least once a week.

Agree with previous post that it should be taken out though.

260498 2004-08-11 12:30:00 If that was a Lithium Ion battery, I would suggest the fault would be with the laptop charger circuitry more than anything else, as that should not happen.

If its an older NiMh battery, then its *possible* but those are not common on newer laptops any more.

From www.batteryuniversity.com:

"The question is often asked if one should disconnect the laptop from the mains when not in use. With lithium-ion it does not matter. Once the battery is fully charged, no further charge is applied."

And that is my experience as well. My laptop is on charge 24/7, with occasional forays out in the field. The battery has been going 18 months now and is still fine.

260499 2004-08-11 21:39:00 I have had my Apple iBook for almost two years. I run it on power 90% of the time, and just use the battery on the odd occassion. I have never taken the battery out of the machine while it is running on power (doing so would leave a huge gap in the chassis anyway), and I have never fully discharged the battery.

Despite this, the battery still holds its charge just as well as it did when it was brand new.

260500 2004-08-11 21:55:00 I agree that modern batteries (Li-ion) shouldn't be a problem, but I think that no using battery power at all for six months would be asking for trouble.
I would use it on batteries at least once a month. I have a notebook that goes for months without being turned on, but that isn't plugged in to power in between uses.
Execs that leave laptops on desks for a year then wonder why the battery is no good deserve all they get.

260501 2004-08-11 23:43:00 Thanks for replies. It is a Li-ion - have used it charging and discharging for 3 years with no worries. Will leave it in and continue to use the battery regularly. Shortstop (632)
260502 2004-08-11 23:52:00 My laptop battery died completly.

2 weeks old when she retired.

Shattered.

Must get around to getting the replacement.

260503 2004-08-12 01:24:00 well well well.

Seems it pays not to swear at the man behind the Asus helpdesk.

Brought the entire conversation to a halt,then i had to jump though hoops apologising to the guy before we could continue.

Well done on his part. :D
