Specifically battery charging.

HP Mini 210, not charging its battery. Windows shows it as battery present, not charging. HP Diags tool shows it as present, but very flat. Charging light on laptop show its not charging.

So, battery or system board?

When powered up, 3 connections on battery have approx 3v, other 2 have 0v


Can't see any obvious failed components in the areas around the charging area of board.  HP Battery diags show the battery has been charged 34 times.

This happened to my lads laptop turned out to be the battery

It will be the Battery

Most likely the battery, but you might have a faulty charging circuit. The most likely cause is a loose connector centre pin, which will arc for a bit with a bad connection which builds up a layer of oxide, which then completely isolates the pin. A cleanup and soldering the centre pin will repair it, but as it will be mechanically weaker you will always have to be careful when the lead is plugged in or it will happen again.

I believe psu connector to be good, based on the laptop works fine on ac power...

If your psu connector ok (and no burns on mobo in that area), then most likely culprit is battery

Thats what I'm coming around to.  HP have made the actual power socket seperate to systemboard on this model, with flying leads. So no issues with mechanical/dry joint probs.

HP Diags show the battery has been cycled 34 times (seems about right), but is 2.5yrs old.

So before I splash out, anyone local got an HP Mini 210 I can test their battery?

[dbug]

Sorry can't help with spare battery.

Remember pattern parts ok

Based on the fault description thus far, I'm quite happy to bet on the battery being duff as well.

Have you thought about the mother board and not the battery cause my lap top was not charging  and not coming on so didn't know what was up with it but when i got pete to use  my charger on his lap top it worked and i thought what could it be so took it back to powerhouse/ currys to be sent for a repair and it was not the battery but my mother board went and i only had it 3 months when i brought it in april of this yr

[freecall666]

batterys have a chip inside for charging and over load power they fail and battery will not charge, its a little 6-8 pin chip in the battery, can change them with another one from an know battery cell dead one and will work again. have had to doit to a lot of old laptops were the batterys have faults and they dont make them any more, can buy the cell's on bay,  but not the chips.

That was my query, its either battery or systemboard

The chip is not that intelligent

The cells are reported fine by the chip, thus Windows sees it as a healthy, if somewhat flat.


For future reference, you must never, ever, ever replace any less that the entire compliment of cells in a Li-ION battery pack. Ever. Thats approaching the same league as the daft bint jouring petrol near her gas hob 

In fact, changing all cells in a Li-ION pack needs to be done with extreme caution, and isn't really cost effective to DIYers, due to shear number of cells needed to get matched ones.
