I was using my friend’s Acer Aspire 5540 notebook (mine went to service center). One strange thing that happened was his notebook making a long one second beep like every ten minutes.
I am pretty sure the beep was coming from pc speaker because the main volume has been set to lowest setting.
At first I thought it was from the battery full indicator, but after using ac adaptor directly, same beep still coming out randomly.
CPU usage is not high and so as the temperature , so ruled out overheat problem.
Searching in the Net for similar problem I found the following:
It’s just 1 beep for like 1 second, and everything still works after it beeps, and it seems to only do it when I’m running Windows :confused:
and it is not battery (it’s on AC) or windows finding anything, because i’m just running outlook and a few apps for work
Anyone facing this strange beep problem on your Acer notebook?
One thing: Acer notebook keyboards flex! The keys went down too much when I typed, nothing to complain… begger can’t be chooser..
