Could i simply buy a chip and re Z9solder it any help would be appreciated
Keep Well be safe
Thanks To any one who reeds this
With the right tools, yes. But there may be more you'd have to do. The chips don't burn up for no reason, so before you replace the chip, you should get the datasheet, take off the old chip, then test all the powerlines first. It's probably not blown for no reason, so it's important you check out what caused it to pop.
That chip is what they call the Super IO chip, it does your keyboard interface, voltage monitoring, fan control etc. It's a multi-function chip.

It's a hacky way to do it, but can be used if you are REALLY stuck. Hot air station is the best way.
You'll also need a multimeter with decent probes, so you can test the powerlines with the chip off the board. Which may take some doing, as I think it needs that chip to power some stuff on. :-) You might be jumpering things out to test them.
But do try and figure out what caused it to burn up. Look for shorted caps, or regulators (LDOs) that have failed. Because if you don't find what popped it in the first place, it may just burn up a new chip.
I wish you luck in your repair adventures. :-)
