m15 R6, not turning on

The light in the adapter is ON

Hi @PUgalde welcome to this free user-to-user Alienware laptop discussion forum. 

Not opening system up in fear of breaking something, limits your options. Dell expects users to upgrade their system and removing the Base cover does not invalidate the Dell warranty. 

If Alienware m15 R6 has extended Dell warranty, please click on Contact Technical Support and request home visit by their designated local-to-you contractor. Dell guarantees 100% the work undertaken by their designated contractor and installation of Dell replacement parts. If there is a local Dell repair facility they should be nominated by Dell Support. You can request that system is returned to Dell for repair, you must wait for Dell to collect the notebook in its as delivered configuration. Dell will reinstate all drives to their as delivered configuration (all your applications and data will be lost). If you have another PC, clone (copy) your drives. Macrium Software Free software is suitable, Macrium Software | Macrium Reflect Free Trial.

This work perfectly, but a technician did it, I don't have the confidence to open the computer!! Thanks though!! 

I was about to use my computer and I went to turn it on and nothing turns on. No fan sound, no lights and power button remains blank too. I drained the power by unplugging the battery and that help to turn it on again. The problem is that the computer is keeping doing the same thing many times and is very difficult for me to keep doing that in my job. In one single month it happened at least 5 times. What can I do to permanently fix that problem??

Does the same thing happen even if the battery is disconnected?

Yes!! Not just me but also a Dell Technician and is still happening!! 

Follow the reset process that you followed a few weeks ago:

1. Disconnect all peripherals: printers; USB devices; media cards; USB hubs and extenders; etc.
2. Disconnect the AC adapter.
3. Disconnect the battery.
4. Press and hold the power button for 30 seconds to discharge any residual electricity.
5. Reconnect the AC adapter (without connecting the battery)
6. Reboot the laptop.

Run Dell Diagnostics:
Immediately after pressing the power button to turn on the laptop (or after clicking the Reboot command), press F12 repeatedly to enter the One Time Boot Menu, select Diagnostics and press Enter. The Dell Diagnostics will test all your hardware.

Run it like that, without the battery, for a while, including shutting down and powering up multiple times, to see if the problem occurs without the battery connected. If the problem does not occur, then the battery may be the problem.

Once you reconnect the battery, test it:
Open an Administrator CMD prompt (CMD, run as Administrator).
Paste this command, and then press Enter:
powercfg /batteryreport

And run Dell Diagnostics again with the battery connected.

That will show a figure for the designed battery capacity (when new) and the current ("full charge") capacity.

Did you do everything that I suggested?
Did you run it through many power-off and power-on cycles without the battery?
Did you run the full diagnostics, both without and with the battery?
Did you run the battery test?

I have done that before many times, but why is still happening??

Not a solution, I needed to send the computer by mail for a whole check out!!
