No sound on my laptop after it rained on it

[Katycampbell]

Hi,

I lost the sound on my HP Pavilion DV7 after it rained on it. There is no sound through the speakers, no sound through headphones BUT there is sound transmitted to my TV when I plug it through HDMI. I hope this is a sign that it's not completely lost. What do you think ?

Is there an IT wiz who can give me some tips ?

many thanks

Katy

Katy, Turn your laptop off!! Take out the battery and leave it for a few days. It should dry out and if you are lucky no permanent damage has been done, having power running through it could fry the components!!

Hair Drier! and lay it face down.

These guys are right, if an electrical item gets wet, you need to take out the battery asap and dry it out thoroughly. Hopefully it's not too late!

Ditto...if you use a hairdryer don't have it on a very high setting, too much heat could damage an internal component...

It's probably moisture across a couple of points on the speakers and headphone circuit. Leaving it to dry out properly should solve the problem.

Leave it for a few days ahah ?? I am working with my computer all day, I can't have it off a few days lol. It's been a week now since that happened, and I am using it over 10 hours a day, I would think it had time to dry by now.

Firstly check what happens if you change the settings sound output to various other devices. It sounds like you use HDMI sometimes, but not all the time.

Some applications on my own laptop (principally browsers) have always been a pain in the arse when changing outputs. I sometimes need to restart applications after changing output devices to swap between HDMI and headphones for example.

In the worst scenario, I'm afraid your HDMI card and your normal sound card for speakers/headphones are very likely to be different hardware. This means it is indeed possible to fry your normal sound card with HDMI sound still working.
