So I posted a few weeks ago asking for opinions on the Surface Pro 4, trying to decide if I should pick one up and slap Linux on it.
Opinions were…mixed.

I got a decent deal on one, and that’s partly why it’s taken me so long to post an update. It was cheap because the previous buyer had returned it to the seller claiming that there were power issues. The seller said they hadn’t encountered said issues in the hour or so of testing they did, and I call fucking bullshit!
Once powered off or restarted it was taking up to 48hrs before it would grace me with booting up. And usable time ranged for 15mins to an hour before system lockup resulting in either a freeze until battery run out, or immediate system shutdown, and another 12-48hrs wait to power it up again. Obviously this is suboptimal.

Part of the issue, possibly unsurprisingly, was windows and the stripped down BIOS. After turning off secure boot, turning off the “battery saver” mode(restricts charging to 50% of total capacity) and scrubbing windows off the drive like a crusty booger…things have improved. I’m still unable to restart the device, restart powers down, but no power up. Wait times to power up again went from probably 36hrs average to 2hrs average, and if I just don’t turn it off, the system is stable.

My time with Nobara on the surface has been really enjoyable, everything is just stock, I’ve not wanted to muck around too much and get attached in case I can’t figure out the actual root cause of the power issues.
As such, not really much else to report other than Nobara running well, and pretty much everything running as well or better than when windows was installed. Touch functionality works slightly differently in Nobara than Windows, but that’s not really a bother for me.

If any of you greybeard wizards has any ideas on what might be happening with the power cycle issues I’d appreciate some suggestions. I think it may be a battery issue, but I’m waiting on a hot air station to be able to open it up and have a proper look at it’s guts. Doesn’t seem to have anything to do with temps, that was my first thought but that didn’t pan out.

    Two hours to power on? Did I read this right? What happen during this long power up sequence? Is it stuck on POST, bootloader or kernel load?

    Ditch it, the Surface Pro 4’s are cursed via shit manufacturing.

    Its screen will fail sooner or later https://flickergate.com/ . I had one, it started flickering after the “extended” warranty. The display is useless now. Nothing fixes it. At first the flicker stopped if something on the screen moved, so I used this https://github.com/Acie1998/Surface-Pro-Screen-Flicker-Solver to mitigate it. But within a day or two it was worse. I tried a reduced refresh rate, but that did not help by then. It quickly got worse when in use, within minutes after a week of the flickering starting. A used one is just pre-accelerated to its demise.

    Replacing the screen - even opening the device - is egregiously dangerous because the screen often cracks when taking it apart. Microsoft abs sucks for making a device that can’t last when it clearly should. (Not to say anything about your specific problems! It sounds like the battery needs to be replaced, but it can run without a battery as far as I know so not sure why it can’t power up with it heavily depleted)

    Edit: if you’re going to remove the sceeen, replace the battery and replace the screen with a surface pro 5 screen. They sell them. The batteries get fucked quick cause the heat sink cooks them, so it’s prob the battery causing your problems (mine had shit battery life at its end too)

    Here is a blurb from Reddit describing what to get (ifixit apparently sells a surface pro 5 screen as well if you want one degree better than direct China): My advice, if you have a Surface Pro 4 with an Samsung Panel is to replace for an LG Screen from Surface Pro 5/6. You need to buy this LCD cable too for that conversion: M1010537-003

    You can check in the device manager which LCD panel you have on your Surface

    If you’re having power on issues, I would make sure you are using a standalone power brick. I’ve used a Surface Pro for work and I’ve found that sometimes when connected to the docking station, it wouldn’t power on. When connected to a standalone power brick it usually would. For a standalone power brick, I’ve used both the one that came with the Surface and also a 65W USB-C adapter with a USB-C to Surface per cable.
