touchpad overheat?

[detailfreak]

hi,
i have a dell inspiron 1525, dual core, 1gb ram, 160gb hdd. a few weeks ago i did a clean install of windows seven x86 (before, it was vista). a couple of days now i notice that the touchpad is getting uncomfortably hot. the rest of the laptop is normal temperature. buttons aren't so bad, it's really the touch area. what could cause this?

Could it be the hard drive bay next to it? Check your temp
