I had to replace the mother board in one of my laptops
and now it will not boot up.
It powers up the fan and the HDD but a blank screen is all I see,
no beeps nothing.

Is there a procedure when replacing a system board other than just bolting it in?
Everything in plugged in tight and no extra parts are laying around. :throw:
thanks

Normally that is CPU is bad , BIOS will not post and no beeps , check to see if you have maybe inserted it wrong , ZIF (zero insertion force) sockets are fool proof usually or bad Motherboard .

Mother board is new and everything transplanted worked before.
Swithing back to the old board, everything works.

Dumb question here , then why are you replacing the Mainboard if it still worked ?
ESD is a killer , wrist band a must !
Bad graphics chip ?
All Mainborads I have done are just plug and play , of course setting things in BIOS (date/time ....etc) .
Those ribbon cables are tricky some times and can slide into the holder but not make contact , there is usually a couple of tabs on the side that you have to push down to hold the cable in .

The AC jack is bad.
I'm reading some articles about removing some drivers before switching boards.

If the Mainboard is a lot different it can pose a problem with drivers , but if it the same type usually not , like a Asus A150 (not real board numbers) replaced with a Asus A150 , no problem but a Asus A150 to a Shuttle C120 then yes .
Via versus Intel or Nvidia chipset yes for sure or Nvidia to ATI graphics yes .
Most of the time "post" will still show graphics , just Windows will balk at booting with driver issues or just do restart loops .

I removed the smaller memory chip and now it boots.
I find this odd because this is a factory part and the slot it was in is the internal one.
