Laptop crashed for the 5th time in time span of one year

I had purchased the laptop in February, 2018. Then it started crashing as follows: 1st time, August, 2018 - the software had crashed 2nd time, October, 2018 - the software crashed, again 3rd time, February, 2019 - there was some battery issue due to which my laptop wouldn't start at all, no display, nothing 4th time, March, 2019 - the OS crashed right after the laptop came back from the 3rd repair 5th time, 17th April, 2019 - it crashed today morning and its not starting again like what had happened during the 3rd time.

My laptop isn't starting at all, sir. How do I possibly do that?

A crash is normally considered to be a BSOD.  If you system is shutting down and you are not able to restart, that is worse than a BSOD.

If you have had it repaired before, what were you told about the problem?  If the laptop appears to startup if you are listening and watching for light indications, have you tried an external monitor?

If it is completely shutdown, what exactly happens when you hold the power button for 1 or 2 seconds?

Can you think of anything that might be common to all the prior crashes?

The 3rd time when it crashed, it was a similar case to how it has crashed now. The laptop isn't booting no matter how many times or for how long I hold the power button. I've tried removing the battery and nothing's worked so far. When it happened the last time, they told me it was something to do with the battery. Now, I'm not an expert on the technical terms so I can't tell you more. All that's common in all the cases is me trying to turn on the laptop and the laptop not being turned on at all. I'm a student, sir, and I really need a working laptop at all times. No other laptop has caused me as much trouble as this one has. I would urge you to kindly either send a replacement of the entire laptop, its parts, or repair it as soon as you possibly can.
