In fact that's how HP ended up killing my laptop as they tried to fix it. Long story at http://www.cnet.com/forums/discussions/laptop-buying-advice/#post-da7ca992-025a-4773-9086-f1d443e405ef
I strongly suggest you go for a full refund since HP seems unable to correct product flaws like this.
Ok, so my laptop doesn't wanna turn on when my keyboard is plugged in via usb port. So far I've been unplugging it every time I turn off the computer but it's getting quite annoying actually.
So IF I forget the keyboard connected via usb port, computer makes black screen and it doesn't go through that so I have to restart. (The black screen is not frozen though)
Informations about laptop (In case you need them):
HP, Windows 7, Service Pack 1
Intel Core, i5-4200M, CPU @ 2.50 GHz,
RAM 8 GB
So, does anyone have any ideas?
