No Power after update

My sister has tasked me with repairing her school laptop

It is a Dell Inspiron 5755 (P28E002). Since she performed an update, it will no longer power on.

I tried battery removal power on. I tried Battery Only. I reseated the ram, I checked all connections. I have tried discharging flea power and rebooting. The power adapter is less than 6 months old, and is testing with the correct output.

I am able to get the fan to spin and get the power light to blink by holding END and powering on, but it goes no further than that. J

My suspicion is the motherboard is fried but I am really hoping I missed something. If I haven’t, then my follow up question will be whether someone has a motherboard at a decent price, and if the processor is removable on this model (Dell part number 1N0C6)

Answer this question I have this problem too

Is this a good question?

Some updates seem to kill electronics, best course of action after your diagnostics is to replace the MOBO and make sure every connection is seated correctly, very gentle and moisture/dust free. also test the battery and charger after the new MOBO install
