The ac adapter. Does it have a light on it, not one on the laptop? Plug in just the adapter to the wall not into the laptop. Hold it to your ear. Is it making any humming, clicking or high pitched buzzing sounds?

My laptop charger, after about 1 and a half years of use, has begun to make a strange, high pitched noise and refuses to charge my laptop.


In most modern laptop chargers, this high pitched sound it emitted when a "safety switch" has been activated in the charger. It is possible that there may have been damage to one of the components in the charger. The only solution is to replace the charger.

The sound on my new LG M227WD is very tinny(high pitched). Have gone into MENU and AUDIO but cant find anything to help increase the Bass sound. Thanks for your help


That's funny, I always complain when things are too bassy. What ever happened to FLAT audio, full spectrum, where you can hear EVERYTHING? I think perhaps your monitor might be defective, 'cause I've not heard tinny audio for years. Can you listen to another monitor at the store where you purchased it to see if they are all this way? Anything in the instruction book to help guide you? Perhaps you can find reviews online which might give you some hints as how to proceed. I hope I have been helpful.

Dv6120us power button dont work


None of the buttons will work untill the power is turned on and no sound will be heard.
You might want to try charging the battery by connecting the AC adapter to the laptop and plugging it into the wall outlet.
With the AC adapter connected, try powering up the laptop.
I hope this helps.
Good Luck.

High pitch pulsing & picture now


I would check the set for bad connections. The high pitched sound you are hearing is the high voltage section. If the convergence IC has completely failed, that can cause this as well. Try using STK392-150 or STK392-180. Either one will sub since they are pin compatible and they both can handle more power, thus should last longer. Also, make sure that you use plenty of the heatsink compound when mounting these.
