I am so lost and really don't know what to do anymore. My customers Surface Pro 5 has lost it's touch function after a windows 10 update. Also there is no touch input within the UEFI bios.

Since I am a technician, I installed a known good tester display with new cables and a working touch board. Nothing.

Got a new display from AliExpress with a new touch controller, it worked until the first reboot. Aaaaand it's gone.

I did check the AliExpress display on a tester surface pro 5 and it worked prior to installing it on my customers device.

After I installed it on my customers SP5 it no longer worked.

I feel like this surface pro 5 has a habit of frying display touch controllers. Checked the board for any heat spots or water damage but there is nothing.

All the voltages are fine and no capacitors or resistors are bad.

So what the hell is going on here? Do you guys have any idea what the issue could be?

Reinstalled everything as well btw and tried win 11 with no luck.

Had a similar issue with my personal Surface Pro 5 and had to replace the motherboard.

This is how ever a 1TB i7 board and it would a shame to trash it.

Best regards

I have replaced the battery on my Surface pro 5, and the screen displays a white line upon turning on.

I tried reseating the ribbon cables etc, but no luck, did I brick the screen on disassembly

or worst the table itself?

Thanks for the answers!

I purchased Surface pro 5 display and converter cable to my Surface Pro 4 tablet.

Everything works well and I haven`t glued screen yet because I`ve doubts that if connector in screen stays there without EMI shield.

Anybody know where I can get EMI shield for connector in screen ? Shield that is in Pro 4 display is too short for connector in never screen model.

Despite this, the battery is still sending power out to the system. I can unplug and use the device just fine, but when the battery dies, it immediately shuts off. No low battery warning, sleep state, or low battery icon from the UEFI when you try to power it up. Just a black screen.

This tells me that the battery is seated correctly in its spot, but something within the software is messing it up. I've tried reinstalling drivers, doing windows update, and performing a Surface Diagnostics Test, but to no avail. I have yet to try a full re installation of Windows.

If someone has any tips or solutions to this, please let me know. Thanks.

I am looking for a battery of a good brand, similiar to the OEMs., as the original ones are not available anymore. Is the one listed here on this site a good one? Or do you know any shop or other brand closer to the original's battery quality?

Thanks for any response.

Does anyone know the part I could order to replace this? Also, is this something someone with a decent soldering iron can fix or is it more complicated than that?

Working Connector (Open)

Pieces from Broken Connector

Piece with an Identifying Mark (712)

Working Connector (Closed)

Broken Connector left on Board

Ribbon that Connects to the Connector

Many thanks.

The screen is not cracked, but I was wondering if it was a connection issue. However, why would just a strip display like this?

I have come across 3-in-1 Function Heat Blower and Soldering Iron (see link below), which I thought could be helpful with other projects also.

https://www.jaycar.co.nz/3-in-1-function...

Has anyone had any experience using this type of "heat blower"? First thought is it may be difficult to control the temperature...although it does have a flame adjustment setting.

Thanks in advance for your help.

The one thing I am confused about is, on this model, the antenna do not connect to anything on the motherboard, or am I mistaken?

There is a little metal piece on the bottom of the assembly (3rd pic) which connects to the motherboard but that piece does not attach to the antenna whatsoever.

I have attached some photos of what the antennas and the assembly look like in my case.

Thank You in Advance!

I do have a screen protector on the screen. Might this be the problem? Or do I have to open the device again? Maybe there's some current acting as phantom touch on the whole screen? Magnetic interference? Surface pen works flawless.
