The laptop does not turn on.
No recovery, no leds, no nothing.
If I take off the base, I can see the ssd M.2 starting for about 3 secs and the fans runing 1 sec, nothing else.
I tried the energy drain but still not working.
I'd really apreciate your help.
Could you please post the model number of your system? The following support page may help. You can also try removing the CMOS battery (coin cell) out of the system for 15 minutes. Then after 15 minutes reinsert it or better yet replace the battery.
Thank you for your answer.
I tried to remove the CMOS battery but not for so long. I'll try again for these 15 min.
The laptop is a Dell Inspiron 5577 with the i5 7300hq
