Sorry to bring up this old thread. I was just too pissed off at the problem at hand so I just want to vent.
My M1210 bought at end of March 07, with the Samsung screen installed. The screen is washed out and overly bright compare to my co-worker's M1210 with Toshiba. He noticed there were some flickering on mine. Since I didn't really notice it, so I left it as is.
The screen started to make buzzing noise when I use battery and brightness was up to the 2nd from the max. As soon as I set brightness to max, the backlight buzzed and turned off.
This problem happens only when battery is used. Dell thought it was the motherboard issue, sent the notebook back, motherboard swapped. Came back, same issue happened. Call Dell again, they ordered a new screen for me. Notebook was returned again, they held it for 4 days, came back and NOTHING was changed.
Called Dell, they re-ordered the screen and dispatched next-day on-site service even my contract was Return to Depot. Screen was replaced with AUO, nice!! Thought problems were over... NOT!
My screen was buzzing again... with or without battery. It buzzed at pretty much all levels of brightness. I really did vent my frustration at the Dell tech (I apologized to the guy after). The guy nicely listened to me, and placed me on hold for about 20-25 min, he came back to check up on me once every 5 min or so. He ended up ordered a new system for me to replace this dreaded one I have now.
The new system will be newly built with the exact config, I just have to swap out whatever I upgraded to the new one, and send the bad one back. He estimated the new system will come in about 2 weeks like the usual time it takes to order a new system.
I will keep you guys updated on this problem here.
BTW, I am in Canada. Dell contracted Soletron as the service provider for Depot service. They are really bad... I just can't emphasize any more... The On-site support is contracted to Unisys, these guys are pros. They repalced my screen in less than 1/2 hour.
