A teardown of Microsoft's Surface Pro reveals the new tablet is virtually impossible to repair. The site gave the device a Repairability Score of 1 out of 10, a full point lower than the already very hard to repair Apple iPad.
iFixit mentions there are over 90 screws inside the device to keep components in place, as well as a ton of adhesive to hold everything in place, including the display and battery.
The conclusion is that any potential repair requires a high level of expertise, even just getting into the device has a high risk of damaging components. You can check out the full teardown report over here.
