Is there a sim slot on my hp 4520 s

there is no sim slot per se, the slot is a card reader. You need to install a WWAN to be able to use a sim card on your machine. Hope this helps

Pro-book 4520 won't boot. I switched on this morning. The windows (7) logo appeared, then blue/black screen and cursor only. Would not boot up. Ran diagnostics which said all OK. Still won'

The windows files are corrupted or the hard drive has issues, load cd installation disc if available, if that fails have the hardware checked for possible replacement.

Hell! I bought Hp probooks 4520 recently in early week it was runnig good but after a week its numpad is not working I don't know what happened to it. I tried so many thing but still not working anyone...


There is a key - Like Caps Lock - that activates the numpad, called Num Lock, and indicates that activation with light.

If not activated, the numpad will act as arrow keys.

Please, Tell us your results.
Good Luck
