The laptop took a lot of time to start when it finally did start, it was working unusually slow. I closed the lid so it went to sleep mode, after 30 mins I tried to wake up but it didn't. Only LEDs were glowing.
After loosing patience, I forced shutdown by long pressing power key since then the laptop just glows LEDs for a second whenever the power key is pressed and doesn't turn on.
It was charged to 95℅ the last time I used it
The laptop is Lenovo Ideapad 330
It's 20 days old and removing battery isn't very easy and also it may Void the warranty
I would try a hard reset first:
1. remove the charger
2. hold down the power button for 30-40 seconds
3. some of the non removable battery models actually have a small reset button on bottom that you can press with a paper clip. If you have that, then hold it down for 30-40 seconds.
4. plug back in the charger
5. try starting it again
If that doesn't work, then you should call the manufacturer and have them send you a new one since it is brand new. You shouldn't have to troubleshoot a new laptop past that point.
