That password blocks almost everything in BIOS. I tried few times un-plugging CMOS Battery and holding or pressing power button, command prompt lines, but completely nothing works.

Service tag is: CD0YX52

If you can help me with that i will be very grateful,

Dell Precision M3800: Why is my laptop not turning on?

Mon, 30 Dec 2024 05:38:08 -0700

Hi friendly fixers!

I got an annoying problem with my laptop not turning on, just thr light of the power button turns on when i click, turns on for 3 to 5 seconds then shuts down.

The last time when it was working, i always get a message that says such this: the performance will be adjusted to match the power. I think the keyword wattage is presented. Also i think it cant recognize the battery, and it was not working and not charging that period. Also the if i am can remember, it also can not recognize the adapter, but still working with very bad performance, then suddenly when i try to turn it on, it shut down the problem appeared.

Also i think the power jack got a problem, because when i last time turned it on, it suddenly shut down, then i turned it on, it started to the logo then shut down again, one last time then the wont start again.

I hope you would help me!
