Laptop Power on problem

[Tirthankar Bala]

I have HP d15-103tx 

Few days ago my laptop won't turn on , so I send it for repair , then I try to change HDD to SDD , laptop won't turn on , then again send it for repair , today I got it , running fine then I try to install HDD via caddy , laptop won't turn on , what is the problem , can any one tell???

 

I tried basic troubleshooting like discharging , without battery , ram clear, etc.

Either problem lies within AC adapter or (more likely) AC jack inside a laptop, which might have loosen contacts.

At least it sounds like it.

Laws might variate in your country, but usually if the device is not older than 6 months (after purchase date stated on your recite), you can ask for your money back or a brand new device, especially after 2 failed repairs.

If it's older than 6 months, you might still have a shot for a brand new (or refurbished) unit exchange if you complain a little as it should not take 2 repairs to still not repair something.

HP & Dell use awful 3rd party repair companies most of the time, we got enough experience with both of them at work and it's very often a level of amateur incompetence on why the devices fail after being repaired.
-> Make sure that the battery &  fans are plugged in properly. In fact, unplug them and re-plug them in yourself.
