Ideapad 510S won't boot up on battery

Hi all, I've got a strange anomaly with my 18 month old 510S 14" running windows 10. A couple of days ago I opened it up to boot up on battery and nothing happened. I plugged in the AC power supply and it fired into action. The battery indicator was showing 78% and charging. So I unplugged the AC and the machine shut down instantly. I plugged the AC back in and booted up without problem. I left it on for a while, then unplugged the AC once the battery had reached 98% charged - this time the machine stayed on using the battery. Then I experimented by restarting just on battery, and all was good. Then I shut down the laptop, left it for 10 mins, then tried to start up - nothing. Plugged in the AC and it came to life, still saying the battery was at 98% and charging. After several hours of online research, and assuming it was a battery fault I bought a replacement. I fitted the new battery, same issue. So it will restart on battery, but not boot up from cold on battery. AC is good and charges the battery, and once the machine has booted up I can unplug the AC and the machine will stay running on battery only. Anyone come across this before, or have an idea what the culprit might be? Many thanks in advance.

Re: Ideapad 510S won't boot up on battery

Hello CJF68

Thanks for using the Lenovo forums.

If this continues to happen with a replacement battery, it will likely be another module at fault here.


You can rule out any software issue with the unit if you perform a factory reset on the unit.

Note: Please back up all your data as running this reset will delete any data on your machine

1. Turn the machine off and press the recovery button which is located usually next to the power button. If you have a desktop machine you will need to power the machine back on and keep tapping the F2 key.
2. Use the arrow keys and press enter on system recovery. ( Desktop users can skip this)
3. Select “restore from the initial backup” and then “Next”.
4. Click “start” and accept the warning messages.
Length of time can vary depending on the speed of the machine.

If the issue persists after it, then it will definitely be a hardware fault, in which case, I would recommend that you get in touch with your local Lenovo supprot line for a repair.

Below is the link to the phone list where you can find these numbers


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

Re: Ideapad 510S won't boot up on battery

I had the same problem, on my Lenovo IdeaPad 510s-14ikb: The notebook didn't boot unplugged, even with charged battery.

Important to mention that if it was in sleep, it worked, so it was not a button issue.

The problem was after a "shut down".


The solution came unexpected. I wanted to update the BIOS but it kept throwing the same error. I searched on the Internet and found that it was because I had legacy BIOS with Windows booting from MBR.


After reading instructions from microsoft site, I created a bootable USB stick with WindewsPE, and I used MBG2GPT to change the boot method. After that I put Lenovo firmware to UEFI mode and to my surprise, I could boot after a shut down, unplugged!

This was before the BIOS update, so the update has nothing to do with this.

Re: Ideapad 510S won't boot up on battery

@AlexeiR  Thank you for the information. Bizzarrely, my 510S came good all by itslef about a month ago, I hadn't got around to posting on here about it. I'm not sure if it was the result of my tinkering or something just clicked into place and it remembered what it was supposed to do!
