high cpu usage on an Acer aspire travelmate notebook

taskmgr shows about 50~60 cpu usage ...

use process explorer to check ... interrupts uses about that amount.

tried this and tried that,,,'

eventually caught glimpse of another user forum complaining a similar thing related to battery

pull the batt out, cpu usage dropped right away

interesting thing is the onbaord  kb/ mouse are not so responsive when cpu usage high, but external USB k/m are fine...
