Why: can you explain?

[BeSiege82]

As of late, I've really had to wonder about my dell laptop. Here is my question: When I touch my touch pad, it tingles. Why?

What might be causing my finger to tingle when touching the touch pad, because this seriously doesn't seem right...

Re: Why: can you explain?

More or less, we can narrow that down to two general areas.

Mechanical causes:
*Electrical short
*Broken touch pad contacts -- Broken-off pieces under the pad might give the illusion of a "tingling" sensation under the fingers.
*Location of the HDD -- Depending on the location of the HDD, you might be feeling it spinning.
*Static build-up -- If your laptop's power supply is insufficiently grounded (basic check: does the plug/adapter have two or three prongs?), it may be building up static inside the case and discharging through you (should not occur--but still can--when unplugged and running on battery).

Medical causes:
*Beginning stages of Carpal Tunnel
*Poor wrist posture over extended period of time (basically putting your finger to sleep//cutting off the blood supply)

The two mechanical causes I put in bold are the most likely of anything from my list (I'm pretty much 90% certain it's probably static build-up from an ungrounded plug/adapter with ~9.9% chance of the HDD's spinning and <0.1% chance of the rest combined).
