How is it that my friend's laptop battery is more than 100%...

If you had GNU/Linux you wouldn't have this problem...

Since the battery display program would probably crash

You get extra battery if you use windows. Good for him.

Plutonium based batteries are a thing now.

It's legit from tech perspective and is actually true.

Batt indicators take current charge and divide it by capacity. Over time capacity drops, but since lappy is on a charger its batt controller still sees max charge higher than capacity [ac is boosting the number up]. As soon as you disconnect the ac, curr_charge will drop rapidly until it reaches capacity value [bcz batt is worn out] and then the drop will stabilize.

It's because of the hardware..

There are 2 options: either allow >100% values or allow sudden % rises from, say, 65% immediatelly to 100%. I prefer the former as it clearly indicates a battery fault

Same problem i went through, my battery was showing 133hr and sudden shutdown while running, i changed my window and unplugged the charge as soon as it full,not over charging it,also making the use of battery instead of plugged in every running, making this as a habit after all this are with limited capacity so don't overcharge it

Obviously its because the outlet where its plugged in has 155% energy left and the battery has 100%. DUH!! :P

It's a feature.

You could have had more battery if the value wasn't stored in an 8 bit int. 😐

@grumpyoldaf you NEED extra battery if you use windows.

May be theree are more than 2 batteries

@Lensflare Never thought this could be a 8-bit integer variable. Thanks for pointing it out.

@alexbrooklyn I use both. This is my friends laptop who also uses both. Dual boot systems. Battery indicator didn't crash but also doesn't show 255%. This is only with Windows.

Elon musk wants to know your location

That's the new Hyperdrive charging system... You didnt know?
