Is it OK to use laptop with battery removed ?

jjscotman

Hi

I've just received a new Asus laptop but unfortunately got one with a faulty battery which does not charge beyond 87%.
I've been in touch with Asus which confirms they will replace the battery under the guarantee and I have to send it back next week.
I think it's ok for me to continue using the laptop with no battery and power from the mains while I await a replacement
However, as I'm not very techie, would some-one with more knowledge of computers please confirm this is safe and will not damage the laptop.
Many thanks in advance for help !!

Yes it is perfectly safe.

In fact - if you usually use your laptop plugged into the mains the constant charging (without being able to discharge) can reduce the life of the battery.

You can either ... leave the battery out all the time (and put it in to charge when you know you are going to need to use it ) or make sure you unplug the mains power regularly to allow the battery to discharge normally.

Its often the preferred method since on 'some' it can prevent un-necessary charging \ discharging of the battery - as some may have power \ charging circuits that make use of the battery first rather than through the charger side first (IYKWIM)..

Do consider though that the power cables can be easily dislodged so could easily turn off when nudged...

Faulty battery which does not charge beyond 87%

Are you sure it is a fault? Some computers are designed not to charge batteries 100% to prolong their lives.

My Samsung laptop battery stops charging at 80%. Not saying it is the reason but worth remembering.

And are you sure that's not a fault? I'm typing this on a Samsung laptop which charges to 100% every time.

I believe its a power saving / battery saving setting which controls this - didnt prevent my battery dieing after a couple of years.

It should work - I would be tempted to google for "[name of computer] without battery" though.

I say this because a few ThinkPad models refuse to run the CPU at full speed if you power them solely from the mains adapter, with the battery removed. This seems to affect some Macbooks as well.

Try it yourself and check the CPU speed; even if it clocks down, it might still be fast enough for your needs.
