Question Microsoft Surface Pro 4 won't start


Dec 31, 2013

I have a surface pro 4 that I bought from someone 4 months ago. It was out of warranty so I can't go to microsoft as they've only suggested an upgraded replacement for 50k inr (around 700$)

I have been facing the issue of fast battery drain on it. I don't know if it was battery issue or it is just a problem with these devices, because I see a lot of people had questions regarding this. Even when I kept the surface completely shut down, a fully charged battery got drained in just 3 days without even starting the surface.
I have the need to use it only when I am going out because I work from home on my PC. So after a few weeks of not touching the surface I tried to start it yesterday, when I pressed the power button nothing happened. I thought the battery is drained just like before so connected it to the charger (I only use the original charger)

The charging port has a solid white light that is ON at all times when I connect it to the surface. But even after hours of charge the device is not starting at all. Microsoft team suggested me some basic troubleshooting like pressing the power button for 15-20 seconds, pressing VolumeUp+Power button, but it didn't work. I also tried the CPR method that has worked for some before.
The main question I have here is this, does a Surface Pro 4 work on direct power if the battery has malfunctioned ? Because in that case this does not seem to be a battery issue. Because the device is not starting even while charging. If there is a chance the battery is dead (Considering the fast drain in the past months) then I have no choice but to replace the battery myself (I know the risks but have no other choice)
Can't help you with your problem, just some notes:
I have my 4 for almost two years, using it almost daily. Battery runtime has fallen a bit, probably 10%, judging from "powercfg /batteryreport". The longest I've had it unplugged is probably a week, but don't have memories of whether it needed charger or not.
