There are a bunch of different HA270 models. What are the rest of the letters? if you take that oval plastic plate off the back, does it look like this? If so, those four screw holes that aren't circled are for a VESA wall or stand mount. They are likely either 75x75 or 100x100.

The key is the 19V@2.1A power and the connector size. Once you have those matched you should be good to go. The monitor model you provided isn't a good number, maybe the T232HI, which is a touchscreen monitor? Anyway, the connector is likely a 5.5mm barrel…

The UM.HQ1EE.001 model does not have speakers in it.

Right click the inf file and choose Install from the context menu.

The issue isn't likely to be the monitor. Typically those defaults are a problem with the video driver on the computer. If you are running Windows, what is shown in Device Manager under Display Adapters?

If you disconnect the computer, do you still see the issue when the splash screen shows up as you turn the monitor on? How about when you bring up the on screen menus? If it's visible in either of those we know for sure it's not just an issue with the video signal, it's the actual backlight that is failing. The repair…

The TC-1780 models do not support DP Alt Mode on the USB-C port, that's something more likely found on a laptop. The HDMI port on the TC-1780 should work though, unless you have a GPU card installed. If you have a card in that GPU slot then the onboard HDMI is disabled and you have to use a port on the card instead. Are…

Acer n o longer has BIOS versions on their support site for the M3970G models, due to the age. To be safe, just stick with the supported 2nd gen CPUs unless you get the 3rd gen for free or close to it.

Here is one from Ebay, not anyone I have ever purchased from, just the first one that came up in the search:

I believe this has what you are looking for:

Here are the Acer fans, you should be able to use any that fit and have the same power connection:

Every Acer model since the release of Windows 8 in 2012 has the product key embedded in the BIOS. Microsoft licenses those versions to the motherboard, so a motherboard replacement would need a new license.

Which specific SFX14 model do you have? There have been at least 5 different base models, in both Intel and AMD flavors, through the last few years. The newer ones don't support Windows 10, since the chipset manufacturers don't provide drivers for the old OS for the new designs.

Yes, most BIOS revisions come through Windows update these days, especially on models that are newer. And I agree it would be much better if Acer gave us the filename to use for the recovery process, but they likely believe that will just lead to more service calls from people who have tried to mod the BIOS instead of just…

OK, so Intel based laptops from 2018 puts them close to 6 years old. It's not unusual to start having battery problems at that age. When you say you reset the battery, what process did you use? Just clicking the reset button under that pinhole on the back doesn't actually reset the battery, it just disconnects it…

Yes, that picture could be any of a number of different laptops. We need to know what you are working with in order to be of much help. Your full model number is usually on the same sticker as your serial number, it should look something like xxxxx-xxx-xxxx. When you say "jumper holes" do you mean the write protect that is…

Which 514 Chromebook do you have? Your full model number is usually on the same sticker as your serial number, it should look something like Cx514-xxx-xxxx. I assume when you say XL, you mean Excel for Chromebooks? Are you using it through the web interface to Office 365 or through an app? What do you expect Ctrl-Y to do?…

If you told us which computer you have, we could show pictures of some of the connections as well.

I'd do a search for the part number, since I don't have visibility into vendors…

You might be able to run a 1030 on the 90W adapter as well…
