I installed some drivers that should helped me with my Pcmia USB 2.0 CARDBUS plug in card. Anyway, after the install the system asked me ito rebot and I answere YES.

The system did not rebot it stoped when Windows XP try to shut down. I tried press the On buttom and even press the "thinkpad buttom" but nothing happen. Then I open the Battery. After I plugged in the battery again I try to start the computer. Now it only make 4 beep and the screen is black... It´s sound like the system rebot and winxp start but I do not know... I could open the CD-rom.... Please help me out... It´s 4 short beeps.
