You need to do a bios update, I had the same problem with mine right after unboxing it. Go to Lenovo's website. The old bios is locking the cpu speed to 0.49ghz. +1 if it worked for you.
you may need to sodder it back on, if you broke the connector it self then heres the site to buy a new one.....and if you scroll down you will see how it looks like on the mother board....hope this helps............samething happened to me..............http://ziquexwholesale.com/en/sony-playstation-series/psp-3000/replacement-part/psp-1000-backlight-socket-repair-part.html
