Re: W510 Left Speaker Not working

Hi All,

 

I got my W510 last Friday, the speakers work fine, but the keyboard doesn't work well ...

Anyway, back to speakers, I checked the wiring of W510, see the picture:

As you can see, I marked those wires which tied to CPU in yellow. The cover of those wires could easily melted by the heat from the CPU. That may cause short circuit.

 

I'm just guessing


 

 

Do you have a link for the rest of that document, showing what's needed to get to that point?

 

Thanks!

See the link to the Hardware Maintenance Manual listed in the following message (the message explains how overheating may be melting the insulation on the wires feeding the speaker, causing the failure of the left speaker, and tells you what page to look at in the manual to find the above diagram -- thanks to ThinkpadT400s for clearly highlighting the wires that feed the speaker):

Re: W510 Left Speaker Not working

I experienced a similar issue with my W500.  I disabled sound enhancements and then reset everything to defaults.  It worked.
