255% available (plugged in)

I seem to have the same issue, just not with the same reasons stated in the thread.

I keep hovering over the battery icon in the taskbar to see this: 255% available (plugged in).

It’s so weird. But if you kook at the battery icon, it has an X in it. Then I remembered the battery was damaged or uninstalled, so if I unplugged it, it would immediately shut down no matter what.

Above is a replica of the witnessed battery icon in the taskbar, all from memory. This was created using a pixel drawing app.

But, the laptop was school property anyways, and this was a bit of a while back.

In my case it is Microsoft Surface Pro 4 and I can't open the back panel. I tried to follow the instruction from the help desk, but none work, I brought the unit to Microsoft store and they basically said the battery is dead and nothing can be done.

Yea! My problem is same as your. I don't know why, but my laptop has a problem and cannot use without charging. And... It's very fictional but I see a pop-up message when I move my pointer to to battery logo that say: 255% avalible (plugged in)

I kept trying to resolve this issue assuming it was a software issue. However, when I had tried installing and reinstalling the OS, drivers, Lenovo Service bridge, Lenovo Vantage, etc., I thought that perhaps the problem lay elsewhere. I undid the cover and checked the battery cable, as suggested by some of the members in earlier posts. While my battery cable seemed well seated, however it appears that there was/is a loose contact somewhere. I have tried to fasten it using some insulation tape to keep it in place. So far, the fix seems to be working.

Step 1 : Remover the 9 phillips screws on the back of the laptop.

Step 2: Gently prise open the case with a very thin screwdriver or blade

Step 3: Gently check the cable connector from your battery to the motherboard. The connector is in the center of the laptop. See images attached for your reference.

Step 4: Try and secure the cable using some insulation tape so that it remains firmly in place with no loose contact.

Step 5: Carefully place the cover again and refasten the 9 screws. Make sure that you close the bottom lid completely and there are no gaps on the edges. Also do not overtighten the screws.

You should be good to go now.  Hope this helps.

 

I tried to update and reinstall driver, it says i have the best drivers installed on my device.
