Specs for this laptop are here

Machine is used daily, has up-to-date MSE antivirus (complete scan 2 days ago = no threats), and Malwarebytes and SuperAntiSpyware paid subscriptions with real time protection enabled). I last used it yesterday and everything worked fine.

Today, when I pushed the power-on button nothing happened. I checked the voltage output from the a/c adapter and is has 19.66 volts at machine input connector (multimeter set to 20 vdc scale) and (which is within spec for this machine).
Also battery is installed and, although rarely used on battery power, battery has been performing fine.

What now? Is there a fuse I need to check?
I was going to disassemble it to check continuity on the power switch (if possible) but I figure I'd better check with you computer guru's before proceeding.

As always, thanks for any help !!!
