I have a Surface 4 Pro that I purchased in March 2016. Over the last few days, I was seeing a considerable color bleed on lower left edge of the screen. Then I stared noticing that that type cover does not seem to close flat against the screen. On closer inspection, I found that the screen is bulging (curving out) on the lower left side and the screen edge has separated from the frame, exposing a gap, Some of the circuitry inside seems to be pushing out as well from what I can see through the gap, indicating something inside is exerting an outward pressure. I pushed the screen back in and with a little pressure it got flattened. However, after a few minutes use, the screen bulged out again. There is no physical damage to the screen, the bezel or the device in general, no cracks or scratches.
What is causing this and what is a possible solution?
Thanks,
Deepak

Wow thanks! I wonder what the best way to take the screen off is. I saw a cell phone guy do it with a small handheld blower maybe hairdryer? And a metal guitar pick and he used a few real guitar picks every time he got an opening. Problem was he still cracked the screen.
I just discovered there is a setting in BIOS "Enable battery lock".
It is not explained and I had to google to find out what it was.
I suspect if I had enabled it then my battery would not have swelled up. I keep my SP4 plugged in all the time and this keeps it from overcharging.
Possibly, if Microsoft had emailed all owners or arranged to have it enabled during their periodic updates, none of the battery problems would have occurred.
Technically, it is a setting in the UEFI (different technology replaced BIOS). That setting wasn't available in original SP4s and didn't come out until late 2018. MS probably added the capability after seeing the battery problems with multiple customers and having replaced many of them.
We were told about it way back in this thread. I had to update my UEFI to get the capability for my SP4, which was replaced by MS under the extended warranty in March 2019. I too have it plugged in most of the time. With the "Battery Limit" set in the UEFI, charge is limited to 50%. I expect it will last for years to come, maybe until MS stops supporting Windows 10 in 2025. That Battery Limit setting is available from the SP3 all the way up to SP8 (see this link).
It could easily be poor engineering, and quality control, not just charge regulation, since none of my many Li products many predating my model, have ever catastrophically swelled and everyone knows since the beginning you cant charge Li batteries to more than 80%. which is its peak potential. When I had a repair service replace my battery (at my expense), we went thru 3 brands before the final one, and every one before got really hot when plugged in after 2 hours even tho the heat piping was ok. The scrreen would flicker and get fuzzy. Maybe the heat piping or thermostat is inadequate; maybe the battery has QC issues, maybe MS just didnt test enough or thinks they can just ignore or tolerate the bad press. In any case MS refuses to make customers whole and its entirely their fault. Note that Consumer Reports survey ranked this model as not recommended in light of the many complaints.
1/2 year after my warranty expired they were already out of stock, and can offer only the SP5 for $150 off.
I was most afraid of a spontaneous fire (ie Sony laptops) but was assure by MS support gent they are sure there was no fire hazard. IE they tested it bc if there was thatll be huge liability and bd press.
