@Tim136 Have you attempted to connect the device to an alternate power cord or adapter?

Or check with another wall outlet, excluding any surge protectors to check if it works?

The following conditions can be helped by the hard reset:

I have removed battery and tried restart. I have 19.5vdc to the board inside, but still no power to switch or fans. Suspect mother board has crapped out.

@Tim136 You may be right about the motherboard, and you've got two option, since the device is out of warranty:

you may order the replacement parts on the HP Parts Store, If you've already looked for it and couldn't find it on the HP Parts Store, you may want to get it locally at the online store such as Amazon or eBay, etc...as the part numbers are universal.

Or, If you have an HP authorized service center near by, you should be able to take it to them and have it checked,
