Dell Precision M4300 laptop, windows xp professional SP3, Intel Core2 Duo CPU T7500 2.2GHz, 2 GB Ram, NVIDIA Quadro FX 360M, March 2008
LCD monitor for the laptop dims to almost black after a few hours of operation. I can barely see that the programs are still running. When the laptop is connected to an external monitor through a Port Replicator - the computer and programs are operating normal on the external monitor. When I shut the cover and reopen the LCD goes back to normal brightness. I have to reset the display properties to relocate the multiple monitor positions. The frequency has increased from one time in two days to many times in a day.
My Dell service warranty has expired. Can someone recommend a course of action and share with me what the repair cost may be? Would it be best to have this service performed by Dell or a local service? Recommendations would be greatly appreciated.
Dell will simply replace the screen - probably on the order of $450+. Contact an LCD repair shop - the cost should be more like $100-150 to replace the backlight.
Do you know if it possible just to replace the backlights, or do I have to replace the whole screen? I tried searching in service documentation provided by dell, but there is no info about replacing the backlight, only the display panel.
Btw, this seems to be a LCD-inverter problem, rather than the backlight itself.
The inverter is easily replaced - just make sure you get an identical one as a replacement. The backlight can be replaced but the repair is far from a trivial exercise.
Here's what is involved:
Got a replacement from old M65, but I suppose those are pretty much interchangeable? At least the screen is working again. Thanks for the link!
