Y500 Static Electricity/ Grounding Issue

This topic has been discussed before, it might even be in my Y500 sucks thread but here's another one for you guys to experiment with. There is a grounding issue with my Y500, the cause of the touchpad issue and perhaps even the keyboard. Try this and report back: With the laptop laying on the table, without touching any part of the laptop with your body, run your fingers back and forth through the top part of the aluminum cover, in between the speakers and the power button. Use the tops of your fingers, not finger tips but the other side with the hair, more sensitive. Do you feel that static charge? Now do it again with your other hand touching the palm rest and now you are grounding the laptop so you don't feel the charge. An even easier way to see the issue is to run your fingers/back of hand through the top cover itself (the one the display is attached to). Crazy amount of static charge, even with the laptop off. Unplugging the AC adapter will remove the issue. So, is this a power supply issue? Who knows, but this static charge can't be healthy on the laptop I would think since the SanDisk 16gb msata took a crap a few weeks back. I haven't really been following the forums here recently, pretty happy with the Y500 overall but so many little nagging issues with this thing. Long live the Y500 Sucks Thread! And no, I have not been following that thread but I see it's gotten pretty big... LOL

 

I do not have such problem with my Y400. However, just a thought, plug it directly into your power socket and not in an extension (if that is the case). I had this problem with one of my alienware systems. I thought it was something wrong with it, ended up that the extension I was using didn't have proper grounding made. Another problem could be the cable between your power brick and power socket, try another one. What you described, shouldn't happen with any system, doesn't matter how crappy they are...

 

Yes, it is quite possible that something on the socket end is not grounded properly. I am running the laptop off a 220v socket with a 110v to 220v adapter. The adapter does have the 3 prongs on the 110v end, but maybe it is still not grounded.

 

You do not need a power adapter converter. The Lenovo adapter itself converts from 110v to 220v without the need of a power converter. Now almost every item in the market supports this feature; before this was the worst problem everyone could get. Read on the adapter what it says under input (100-240V). If you are just using a 'socket' converter that is a different story. You are better in getting a local cable with the proper connection to your socket instead of all those adapters, sometimes the wiring does not match.

 

Yeah, we are talking about the same thing. Guess the proper term is socket converter.
