Issues with booting Dell Precision M4400
I have this old Laptop that i started using recently worked fine (this one heats so much and i mean up to 95%) until today when it fails booting(well sometimes after a couple of tried it starts sometimes it takes hours).
The laptop starts for like 3-4 seconds nothing appears on the screen,the fan stops working and after a sec i hear a beep and everything turns OFF.
I notice that when i plug the charger and start it caps and scroll lock is always turned on and num lock flashes 22 times until it stays turned on.What does the flashing num lock mean in dell code and how do i fix it.

Hi PrecisionOwner,
The Num Lock key flashing with steady Caps Lock and Scroll lock key indicates system board failure.
Shut the system down, remove the battery and disconnect the ac adapter, press and hold the power button for 20 to 30 seconds. Now connect only the ac adapter and wait for 30 seconds and turn on the system. This will drain any residual charge in the capacitors.
If the issue persists, you may consider replacing the motherboard. Let me know the region you belong to, to provide the contact information to get the system serviced.

Can I get the current hdr bios file?
In Which USB port insert the stick?
If I "D" and "on" switch press does the display test
