Simple one this: Leave the laptop plugged in all the time, or not?

And if you leave it plugged in all the time, what about taking the battery off to avoid damaging it?

I'm sick of seeing the battery running out, only to see the missus has unplugged the laptop at the wall cos she thinks it's going to burn the house down.

leaving it plugged in when it's fully charged kills the battery. So if you're deadset on using it plugged in all the time taking the battery out could possibly avoid that. That being said with no backup power source if youre working on something and the cord slips out it'll shut off instantly lol

As long as you set it to 80% maximum charge and don't discharge to less than 20% then the lifetime of the battery won't be adversely affected.

What kills a battery is frequent deep discharges or to depletion.


I'm in the middle of buying a new UPS for the desktop. Same thing for them.

Anyone any ideas?

The charger went kaput on my laptop and I bought a new one yesterday.

The battery had gone dead in the meantime.

I plugged the power cord in and the laptop worked perfectly.

But when I took the cable out, the laptop powered down immediately.

I have repeated this exercise several times with the same result.

The battery itself is fairly new and was giving no problem at all prior to the charger packing up.

So to sum up.....the laptop works fine when I leave it plugged in with the new charger, but it is not charging the battery.

I'm no tech expert so it's a pure guess, but could there be something in the battery/power settings that's telling it to turn it off when unplugged?

A quick google says that's common with HP laptops, no idea what yours is?

it doesn't kill the battery if it's a Lithium Ion, which most of them are nowadays. Or rather it does, but it's at such a snail's pace the benefits of leaving it in outweigh the negatives. In the days of NIMH to power high-power devices like a laptop and such then yeah, over time such an act would adversely affect the available capacity, it was still a very slow process but you'd notice it if paying attention. Even then it still wasn't worth worrying about. All batteries die eventually, just replace when it's time.

NiCads were probably the culprit where this general myth was born from, they much more than NIMH's were known for this:

hiya khal mate,

what's the model of your laptop?
is the battery an original? if not what mAh power does it claim?
what is the charger's output voltage and Amp rating?


Problem might be incompatility.

Toshiba, Doc.

No, not the original battery.

That sounds plausible what you are saying......I will check all that voltage and amp stuff.

aye the model of the laptop would be handy, as laptops have different power requirements. Toshiba's the brand innit :cheers:

mine for example is an ageing Asus G74SX. It's a 17" monster with two hard drives, a bluray player and a 120hz display...if I'm buying aftermarket chargers/batteries the specs need to be closely matched.
