acpid causes cpu overload when lid is closed

Hi to all.
I've got strange problems regarding acpi stuff.
In fact, when i close lid of my laptop, cpu percentage and temperature suddenly increase, although no apps are running; when i reopen lid, values returns normal.

Some info:

Laptop Model: Acer Aspire 1641 WLMI

When I reopen the lid values of top command returns to the first showed above, and I see that temperature has arrived during this time at about
56°C (also fan has activated in the meantime)

If I stop acpid daemon (/etc/rc.d/acpid stop) problem disappears.

Any suggestions?

Thanks in advance,
