   Before a computer can load its operating system and locate drivers for its components, it must recognize that it has been turned on at all. This task falls to a relatively simple device known as the power-on reset circuit. “In its very basic form, it’s simply a little capacitor and a resistor and a little inverter, something like that,” says David Blaauw, a professor in the Michigan Integrated Circuits Laboratory at the University of Michigan. The power-on reset circuit is hardwired to recognize a minimum voltage level. When voltage crosses that threshold, the circuit signals the processor to execute a set of commands that allow for the loading up of the system.

Very impressive Daniel. .. 🙂
Thanks it's usually between 12 and 16 seconds as I have 2 SSD's Drives and the 108 second one was during a Windows Update as you know it needs time to install the updates on reboot!

 

Daniel
Well Daniel that's an awesome setup so for my next Windows pc I'm going to get that laptop. ..Whoohoo. 🙂
Yea as I only use High End Laptops and I have no need for a Desktop anymore but you can get SSD's for Desktop Towers.

 

Daniel
Really Really. I haven't been updated with SSDs..so I'll keep my eyes on that for sure.. 🙂
It's just my opinion but I have 2 Muskin SSD's and made in the good oh USA for 3 years now without any issues I got them on newegg.ca but for you newegg.com
