700m thermal reset?

The LCD on my 700m quit working after I dropped it. But OK on external monitor. Got new screen on eBay. Part # slightly different but that's moot now. After hooking up the two cables to new screen and putting battery back in, I pressed START button. The light would come on for a few seconds and then blink off, accompanied by a faint click. The data cable to screen got very hot in just a few attempts to start up.

Now nothing works (no more blinks and clicks) with either LCD, on either battery or mains. At this point I would be happy just with external monitor. Had I tripped an thermal overload device, and is there a reset button?

no reset, more likely you fried the GPU,

if you remove the cable for the display - you still get no Video to the external monitor?

Does the laptop come on at all - As in post power on, hard Drive, Power LED, Etc (even though the dispay is dead)

Removed two cables from LCD (didn't yet attempt to disconnect the data cable from under the kbd). Still dead. Haven't bothered to hook up monitor.

On the several start attempts after initial LCD changeout, the power light would come on and HD or maybe the DVD drive would whirr. Then the light would dim and there was a distinct mechanical click -- making me think overload relay -- when light went off completely.

As far as I know there is no overload relay, the click was most likely the hard drive heads parking in the safe position prior to power down.

If the laptop is totally dead now, some thing has fried, at this point your most likely looking at a new main board, as I believe the GPU is intergrated into the motherboard.

You don't have any basic warranty left on the latop do you?

Still dead after removing other end of data cable. Beyond warranty, and had already been back to Dell once for an intermittent problem with the display (which started happening again soon after warranty expired). Crucial files had been backed up elsewhere, and in the morning I'm off to Fry's to get an adapter so can put the HD in my AirLink NAS housing with hopes I can retrieve other data.

DVD doesn't work and WiFi has to be within a few feet of the base unit, so I'm ready for something else anyway. For overseas travel I've got an early model EeePC running Linix (did Skype video from Zanzibar with it), and Office Depot today had some newer netbooks with more capability than my 700m -- for ridiculously low prices.

Tnx for the help anyway.
