Technical Problems

[Gabriel]

Hi,
     Im using ubuntu 11.10 Oneiric Oncelot, with one Hp dm1 3200sp  
laptop for a couple weeks now and i have been with a problem without 
answer until now. For some reason, when i`m on battery power and 
multitasking with my laptop, listening to music, browsing the web ( 
trough wireless connection ), reading mails and writing, my laptop just 
freezes after some time and my caps lock light start to blink. I read 
about that on the ubuntu foruns but couldn`t find where`s my laptop`s 
problem. Please somebody help me fix that issue.

     Best regards.
