Replace laptop motherboard

HP laptop seemed to get zapped and is now dead. Power cord/transformer seems fine though. How to go about researching a DIY solution? For example, how could one tell if a motherboard replacement might be all that is needed, or if there are other components that might have been damaged? Trying to save $$ and not pay to send it in anywhere for determination of what is bad.

It's unusual for them to fail to that extent but it does happen.

Check the voltage from the transformer with a multimeter or get somebody to check it for you. It might be working but it might not be supplying the correct voltage. Do this before anything else.


First, plug it out and take out the battery for a couple of hours. Put back in the battery, plug it in and try again.

Next, try plugged in but without the battery.

You can also try removing the memory and trying a startup as well as disconnecting the hard drive and trying a startup to eliminate both the memory and hard drive. You're looking for any sign of life at all.

If you're not getting any life at that stage, it's pretty much down to the motherboard and you could do a quick search on eBay for a replacement first. This is generally a pretty good way to get cost effective parts... just read the reviews before you order.

By the way, what make is the machine? I tend to fix a good few and failures can run through makes and models.

As far as a laptop goes.....all other componets are normally part of the motherboard (On/Off Switch etc.)  If you are sure the Power Adapter is good.... it should be tested using a Volt/AMP meter to verify it is good.   Then replacing the motherboard should do the trick.  However if you have never done this with a laptop before......I would suggest sending it to a pro.  This is not an easy repair.

Thanks! Is it possible CPU would NOT need to be replaced? Easy way to find out?

How can I get the OEM version of Windows to work again if the motherboard/CPU are successfully installed? Will Microsoft support allow activating it if contacted?

If the power is fine, should the CD work once plugged in even if the motherboard is NOT working? That seems to be the case. If the CD is not working of course loading drivers, OS, et al from CD would be a problem.

I'm basically assuming a new CPU and new license for Windows will be necessary...

Unlikely the CPU would need to be replaced. They rarely fail.

Just contact Microsoft re Windows. They will not have a problem when it's a repair. You may need to contact them by telephone to them but it will not be a problem.  You'll get the number if there is a problem activating.

The CD drive needs the motherboard in order to have anything to do... it is a peripheral.

A new CPU will be unlikely and Microsoft will not have a problem... just explain to them that it's a repair. I have been there many times.
