Advice on laptop batteries

by fr8dogr / February 14, 2010 7:32 AM PST

My laptop is almost always on a table or on my lap at home with an outlet always nearby. Since I almost always have the power cord plugged in, am I shortening the life of my battery by keeping the battery in? Should I remove the battery to prolong it's life? Or does this have no effect on the battery? Thank you.

In short, the gains are MINIMAL. Let's call it 5% longer life than leaving it plugged in. (we did the long discussion and came up with five percent.)

The problem of removing the battery is what happens when a Windows Update happens. You know the one where it warns about not turning off the PC? And without the battery the power could go out and it fails to boot. Seems like a false economy to remove the battery.

Routine Maintenance

Thanks Bob. On a previous post, you mentioned to someone else about refreshing the heatsink compound on a laptop. Is this something everyone should do on a regular basis? If so, how often, and can the "average Joe" like me do it? Is there a link or previous thread that discusses this? Thanks again.

I was average.

Still might be!

Ok, there is a YEARLY maintenance of cleaning the vents. The heatsink compound doesn't wear or dry out for many years but here's the problem. I've encountered far too many laptops with clogged heatsinks and heatsinks that are not attached proper. This is to be expected after a few years of transport and use.

Diving in to clean and refresh that compound at 2 years would head off that trip to the service shop.

But if you don't do your own work then find a trustworthy shop to do the 2 year work.

Be cautious, as many manufacturers will indicate a battery usage time but this may be at the lowest possible settings, ensure that the manufacturer clarifies what the standard battery usage life is when using the portable computer in all power modes.

I hope it will help you.
