Lenovo Z510 Battery issue after 5 months of bat firmware flash

Hi guys,

I have a one-year old Lenovo Z510, I have already flashed the battery firmware 5 months ago.

Now the laptop shutoff at 35% of batter with no warning or notice that the battery is almost empty. This problem was occurring before the first firmware flash and that flash solved it. So please is there any other firmware update because I cannot flash the current firmware (same version).

Re: Lenovo Z510 Battery issue after 5 months of bat firmware flash

Hello Leptdre

Thanks for using the Lenovo forums.


Unfortunately I'm not sure about the Firmware I'm afraid, but please, Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.

The problem is that the battery is internal and I have to open the laptop to get to it. The previous battery firmware solved this issue 5 months ago but I need a new version.

I am facing the same issue again. All of us having the same issue seems to be a firmware issue. Please Lenovo provide us and update.

Have you checked the actually capacity of the battery. It has likely on its last legs going out. Firmware isn't going to correct a weak battery. You are lucky to get two years with 50% still usefull charge. Some decline faster depending on how its used/charged.

The battery wearing out is reasonable. The standby time going from 2 hours to 2 seconds in a day is not, which is what is happening with me. This is exactly the same thing that happened the last time so I'm  pretty sure it is a firmware issue
