I purchased a HP ProBook 4530s in March 2012.

After installing the OS Windows 7 Ultimate x64 & the software

I ran the HP Battery Check Utility Software and came in for a surprise.

The results showed that the Cell 1 was 0mV - but it gave a 'pass' status for the battery.

I contacted HP and received another new battery on warranty.

But the software came out with the same result! Cell 1: 0mV

I emailed HP via their website. The Tech replied that if the software gives a 'pass' then the battery is good!

So according to HP, a battery having 4 cells with 1 defective cell it is ok (obviously the battery running time is reduced).

The interesting fact is that I ran this test on 7 (yes, seven) more HP EliteBook 6930p and the result was the same - Cell 1: 0mV

(I am awaiting a reply from HP for my reply to their Tech's suggestion)

Any suggestions or comments?

I don't understand the voltage readings......

If every battery you ran the test on gave the same result, I would say that they have a defect in their software.

If every battery you ran the test on gave the same result, I would say that they have a defect in their software.

Maybe they have 4 and 3 cell batteries and on a 3 cell it just shows zero for the not existing one?

(just an idea)

What I cannot understand is why the HP Support Tech could not explain the 0mVolts on Cell 1. However, I am awaiting a reply again / if they do!!!

your battery is perfectly fine, if cell 0 had a voltage reading your laptop components would be burned.

battery has a minimum of 10.8V by desing and fully charged at 12.45v according to the software so everything is fine.

Thank you NHJ. This was a big puzzel to me. I am surprised HP still could not give me an answer yet.

The link you gave is the battery checker to run under XP, not Win7

On my pc the battery checker is under the HP Support Assistant,

but does not give the detailed info you have

As shown on your print screen, at the bottom left corner...

Select settings and advanced for the full details.

Hope the above works.

And now HP Support says this!

"Please note, I had check with my supervisor regarding this issue, 0MV against cell 1 of your unit indicates that, that particular cell on your notebook battery is not performing well. Hence, please perform battery calibration 3 to 4 times on your unit and check."

Calibration does not work! Awaiting reply from HP.

According to the HP Support forum, it seems HP is having a huge problem with notebook batteries - I wonder what they are doing about it!

Sorry about that. Here you can find the Windows 7 version - sp54257.exe (9.0 MB)

The software simply has a problem reading the eeprom in the battery electronic circuit, yours is a 6 (dual 3 cells) cells battery.

HP must have hired trainees and assigned them at the support

I am now more confused than ever!
