Surface Book Discussion Thread

It was at 0% when I arrived home, last night. Will give it a few charges to see if it helps. Ordered a 2nd gen Ipad pro 12.9 to replace it. Shame.

Oh well. It is what it is.

 

Huh, looks like the clipboard battery is basically toast (35% full charge left) but your battery in the base is basically pristine. Odd, especially given that they have about the same cycle count. I wonder how that happened. Also, a cycle count of 38 seems low for killing the battery.

Any chance that it's a battery calibration issue but only of the clipboard? Maybe detach the clipboard, keep it on the bios screen, and let it run to zero and charge it separately back up to 100%. If the reported full charge capacity is quite a bit higher after that, repeat that procedure. Full disclosure: entirely running down the battery is bad for it, but at this point that probably doesn't matter too much..

 

<<...Odd, especially given that they have about the same cycle count...>>

...Batteries can simply go bad.

I agree that it's probably worth trying to cycle it at this point. As long as you promptly start the recharge (i.e., don't leave the battery in a state of near-complete discharge for too long), it shouldn't be too risky...

 

Will do. It didn't dramatically shutdown last night so I'll give this a go tonight. Thanks all. It is a shame as it's a great machine.

 

Thanks all! That seems to have done the trick (Other than it still switching off around 20%). I'll reset windows.
