I think it is definitely not fair, 3 years is just a random number, as I used for 3 and half year, the issue came out. But when you spent 1000+ pounds for this device, you are expecting to use for 5+ year right? I think it is worth to raise it, as if it
is faulty design, MS should provide at least longer period of warranty. Below is my email to customer service, but seems they are not really helpful
I started to use my surface pro 4 like one year ago, and use it as my daily PC, it was going fine until recently I started feeling the screen kept shaking and became blurry. I checked online about this issue, and tried several ways to
fix it, updating the software, update the drivers etc.. And I called the customer service regarding this, and under the construction identify the issue is about hardware (I see shaking under UEFI mode). I also found out that this issue is a common faulty issue
for surface pro 4 buyers, and it was claimed that only 1% of the user got affected. I guess I was one of the unlucky ones.
Under the instruction, I called the customer service once more to request a repair or replacement, I was told that the device was purchased more than 3 years ago and they will not support the replacement anymore, and also they will not offer a repair service
either, only solution is I need to spend another ~600 Pounds to replace with a Surface Pro 5 (which you can actually buy a new one from amazon or ebay), where the latest Surface Pro is X already.
I am really disappointed regarding the solution that Microsoft provided, it left me no choice but spending another 600 pounds to buy an outdated product. I spent more than 1000 pounds to buy the Surface Pro 4 with the highest spect at that time, and I was not
expecting to use it for only 3 years. I had my third generation of IPAD and Dell laptop purchased more than 4 years ago and functioning super well, and I am still receiving active support from them. This is issue to me is surely a hardware faulty, and it is
full responsibility to Microsoft that recall this product and replace a new device with same spec for absolutely free, or at least provide very basic service like repair.
I am sending the email here seeking for a solution, and will escalate further if necessary.
