G560 won't run on its own battery

[boac69]

G560 W7 64bit I3 processor 4GB ram.
It has been a long time since I posted here, I often have a read for info but I now have a problem I don't understand and don't seem to be able to find a simple fix for, let me explain.

I was given the G560 with a failed 250 GB HDD and no recovery media so I did a clean install of W7 and added all the Lenovo drivers and progs I could download or were added by system updater.

I now find the machine won't run on its battery, which the machine has fully charged and recognises in power management and says it in good health. I have confirmed its charge state by a battery voltage reading and an internal resistance check also passed, I have gently cleaned all of the battery terminals on both battery and computer still no joy. Computer runs fine on external pwr but just won’t run on its own battery, which I did see it do before the HDD totally failed, click of death!

Any ideas would be helpful as I can’t come up with any despite a good scratch of both upper and lower motivation areas

Many thanks

My sister had a G460 (same generation as your G560, pretty much equivalent except the screen size) once, and the battery couldn't hold a charge even though it says it's at 100%.

I now find the machine won't run on its battery, which the machine has fully charged and recognises in power management and says it in good health.

This is the exact symptom in my sister's G460.

We didn't get to troubleshoot it any further than that, since we had neither an extra G460 nor a spare battery to check whether it's the charging circuit or battery that's malfunctioning.

IMO I think the battery is defective. The G460 and G560 use the same battery packs, judging from the FRU #s in their respective HMMs.

Thank you for your help and you were spot on.

I bought a new battery and no problem it worked as advertised straight out of the box.

Again my thanks
