Dell latitude 5420 dead

[oket]

Hi,

My Dell latitude 5420 suddenly died and wont turn on anymore.
Tried removing the battery and reconnect it, the keyboard led will turn on a split second when i press the power button and the caps led stays on.
It also smell burnt from the upper right corner.

What happened?
Can it be fixed?

Motherboard is GDF40 LA-K491P

No one here has the magic ball to tell you what happened.

You need to take out the motherboard and do physical check for any corrossion/burn marks first.

If nothing suspicious found, proceed to measurements.
