My Lenovo Thinkpad SL500 is saying that no audio
- Is the mute button activated? Usually located at the top row of keys on the keyboard and has a build in light that lights up when activated.
- Do you have Realtek installed?
- Did you connect the speakers/headset and turned them on (if possible).
- After connecting the Speakers/headset, restart the pc while leaving them on and connected. If the driver is missing, it should be asking for one when it restarts.

Possible causes :
1, The most common problem is foreign debris interferring with the momentary contact switches on the keyboard. (95% of the time)
2. The next most common problem is the keys are just worn out but this would be rare since other keys would likely be affected
3. Keyboard membrane underneath is damaged and interfering with reliable contact
A. First, you can try a can of air to blow the debris out and then vacuum the keyboard and all grill openings in the laptop.
B. Second, buy a bottle of 99% Isopropyl Alcohol and with the power adapter detached and the battery removed you can flood the area with alcohol to clean underneath and let it dry overnight. I use alcohol as it cuts the greasy junk whereas water will not and water takes a lot longer to dry out. (Hair dryers will speed it up)
If this is not helpful then the laptop case needs to be opened and the keyboard assembly inspected for damaged switches.
This assumes you have checked the software driver for the keyboard and it is functioning normal otherwise.
