Yet another problem with my laptop

[David DEMELIER]

Hello,

I always have problems with my laptop, this time is a lot of messages
while running on battery :

Jun 20 14:29:51 Melon kernel: ACPI Error (uteval-0318): Method
execution failed [\_SB_.BAT0._UID] (Node 0xffffff0001537760),
AE_AML_NO_OPERAND

There is a lot of these message in /var/log/messages, but I can't see
any troubles with my battery.
