No power when disconnected from AC Adapter

So the problem I'm having with my surface pro 4 is that it dies when not connected to the AC adapter. Instantly as though it has no battery power. Now I know, most of the time this would be the battery. So here comes the unusual part that has me wondering if it really is or not. Battery Report shows that the battery is there, fully charged and functional. And the battery meter also shows fully charged and plugged in. I've Updated drivers, windows and have even reinstalled windows hoping it was a software problem.

Any other suggestions or can we conclude it is just a faulty battery? Thanks in advance.

This is 99% the battery. I can't think of anything else that would cause that. I'd suggest taking out the battery and putting it back in, however, before buying a new one.

Hi,

Sorry, I don't have a solution but some info may help.

Unfortunately, I don't believe it's the battery. Every pro 4 that I've come across (over 20 units with this issue) that has had a battery "go bad" by swelling or physical damage was not repaired by a brand new aftermarket (or oem used) battery. I have tried 3 different suppliers (although the packaging is almost identical to one another) and none have repaired any pro 4's with the swollen or physically damaged battery. The pro 4 will usually say "plugged in, charging" or "charged" with an accurate battery percentage. I can adjust my brightness settings but not the power settings.

I had one pro 4 that the battery just went bad internally, swapped it with an aftermarket battery and all was good. (I tried an oem battery just to see if there was a difference but there wasn't - oem worked as well.) In this case, the bad battery would quickly switch from "0% charging" to "100% charged" with the bad battery.

I've done everything on the internet from drivers to rewriting the bios and nothing seems to help which makes me believe it is damaging or shorting something on the motherboard when the battery damage happens.

If anyone with any insight on this could help, I'm sure all of us would be very grateful.

Thank you,

Hi,

I don't have a tested solution but I have the same problem and I agree with your definition of I do not believe it is the battery.

I think it is related to a ground issue with the power source. I noticed that my tablet works better, no flicker, ability to touch the screen without a black screen when my docking station is plugged into it. Therefore it is probably getting is ground from the docking of the USB etc.

If I disconnect from the AC my surface Pro 4 with a battery showing at 76% shut's instantly. (Less than 2 years old)

if you look under the middle left can on the board, there are 2 black diodes that are identicle to each other. Some say replace only the top, some say only replace the bottom. I replace both every time and 99% of the time it works. Only time it don’t is when the issue is further down the line from my experience.
