Can anyone help?

I have a Dell Latitude 5511 laptop, and lately, a faint but clearly audible electrical (crackling) noise comes from the motherboard, similar to the random clicking coming from a mechanical hdd's heads moving inside it.
The laptop shows no signs of malfunction, and clearly this is electrical not mechanical, so my suspicion goes to a dodgy component in the power rails (a capacitor or a coil?). I fear this could develop into a serious damage.

Any advise on how to narrow it down?

Hello smart friends,

After making bios dump of my Dell Latitude 5510 with service tag 54FD593 and flashing back original dump, my laptop only shows amber ligth when pressing power button.
Please can somebody help me with good BIOS file and tell my what is wrong with file? Thanks a lot!...

hello masters,

i have got a dell latitude that posts only few times, and shutdown itself sometimes too.

i think it is a bios corruption : when i unplugged de bios battery and reset bios, the laptop posts fine, several times. but when i put the battery back, it fails again.

i tried a bios find elsewhere, the laptop boots fine every time but the bios is locked (it was just to test)

here i send you original dumps avec the laptop with chips name
the serial tag is : VD453


can you create a functionnal bios with this ?
