Hello,
To the one who offers help god bless.
I own an HP Pavillion DV1540ca laptop that is just under one year old. At about 10 months of age, I started noticing a high pitched, irritating humming noise. What sparked it, I do not know. It is a piercing high pitched toned that is very consistent and the same note every time. It turns on when the laptop is operating at a higher level (eg. running a movie and an audio file at the same time). It is possible it is related to the harddrive spinning or the fan spinning.
However, I do not believe the humming noise is a result of the an inefficient fan or rattling of the casing because when I plug my laptop into my sound system, the humming (unfortunately) comes out of those speakers too, almost proving it's not a rattling and maybe even a software problem.
I sent it in 3 times through staples, 2 of which went to HP, none of which fixed the problem. Staples said they couldn't hear it (although upon start up I showed them the problem), HP replaced the fan the first time (and probably didn't test it...), and lastly, HP replaced the bottom casing, and the main board. All to no avail. I gave specific instructions on how to obtain the hum and I have gotten my laptop back 2 months later in the same condition in which I sent it in.
Now it is Canada day weekend so contacting HP is out of the question, and I think I will talk to some real people who can help me out.
Please offer any advice you can give. I'm beginning to wonder whether or not my laptop will be fixed before school begins again...
