Lenovo S90. Why isn't sound working? - Lenovo Audio Players & Recorders

how to remove sim slot permanently lock in lenovo s90-a

Is the ac plug loose? If you wiggle it does the light come on and off? If that isn\'t the case and it powers up then goes right off sounds like an issue with your motherboard. If the unit is under warranty I would contact Lenovo. If the unit isn\'t under warranty you should try to blow it out with can air to get all the dust out of it to see if its a simple over heating issue. If the unit still doesn\'t post, sounds like you have a bad motherboard. Let me know if you have any other questions. Good place to find more info: http://support.lenovo.com/en_US/



Just need to type in your model number which can be found on the bottom of the laptop. should be MTM:XXXX-XXX

It could well be the rubber billows in the engine compartment shows cracs, very often a replacement of this device solves the issue

Many of the newer models (if you purchased during the Week/1TB sale Lenovo did) they do no include back-lit keys.
I received mine around 9/19/12 and it did not come with back-lit keys.

Unless you have physically inspected the underside of the keys and you see the diodes, then you should contact Lenovo.

White smoke = water or coolant leak

Check any gasket loss or internal engine damage.

If it happens only on turns then its the outer axle cv joint.. If it happens all the time probably something stuck in a tire. Either way have the suspension visually inspected by a technician as soon as possible.

sounds like ignition coils may be bad

I would get the Starter Checked out. Sounds a lot like the Starter is not Catching on every Revolution Causing this Problem.
