HI, i had the same thing. at boot-up white screen. I found out that is was the backup battery.
Should indeed last 10 years. but my problem is that i don’t use the surface that often. not as a PC that is on all the time.
When the surface is off the BIOS backup is using the battery . When the surface is on the BIOS backup system use the normal power and don’t use the backup battery, at least not that much. That explains why the backup battery went dead after 3 years.
I replaced it an had no problem since. i installed two leads with a holder so i could replace it easier the next time because the standard battery is solderd on to the touchscreen PC

after replacing the battery there are some specific setting you need to change in the bios. you have to connect a mouse and keyboard and at startup go into BIOS an change screen resolution setting. i think 600*800 but it is stated in another post.

if you have good soldering skills you can do it yourself. or let someone do it.
It is al lot less expensive ( 7 euro for holder and battery) than a new touchscreen pc [:)]
