Laptop states "consider changing battery"

bjbyorkshire

My PC is plugged into the mains, at the bottom right is the battery icon with a charger showing 100% full but there is also a Red Cross saying "consider changing your battery".

Is this a crucial problem? If I don't replace the battery but always use the PC in a mains socket will I really need a new battery. The laptop is 7 years old, I don't fancy spending a lot on a new battery, but I'm not keen to buy a new PC until Windows 10 is more friendly.

Thanks

From the other thread:

[A] quick web search suggests that sometimes this can be an error. It might be worth running the laptop on battery power till it's flat, then fully charging again to see if the warning resets.

If not, it means your battery is down to 40% of its original capacity. If you don't care about the battery not holding charge for that long, then it should work for a while yet... about 2 years, 9 months and 18 days at the current rate of deterioration.

I'm not sure, but I'd guess that when the cells are totally dead, the battery electronics will prevent them from charging at all, but should still pass current through to the laptop. So... I think it would still work if it was plugged in all the time.

I tried this - worked on mains for a couple of months then that stopped working as well. Problem solved by a new battery off eBay for about a tenner.

Oh, that's an ok price for a battery. I was expecting it to be a lot more than that.

Battery prices for older laptops have dropped in the past few years!
6 years ago my old HP (about 10 years old!) replacement battery (third party!) was costing around £70. (Original HP was nearly £90)

Bought one a few months ago for £30 (original HP was still in the £60's)

Don't think i got a good deal though! 3 months on and the battery is flat in 50 mins when it should last 90-100 mins! (might need to drain it to calibreate it again!)

But it's better than the 20 mins of my old battery and it's usually on the mains anyway!

Sol, so.. If I am only ever going to use the laptop while on mains, is there any reason that I couldn't just ignore the battery warning or does the battery play a part even when using mains?

Many thanks

If it's only ever on mains then you can ignore the warning,

Told my daughter that never run it on mains all the time, she didnt listen and killed the battery so within a year it wouldnt last long enough for it to fully load windows before the battery warning popped up saying its going to shutdown.
