Hello,
I've just bought a new XPS L421x with windows 7, intel i7, 8GB RAM, and 1 GB dedicated NVIDIA GeForce GT 630M. I have been using it for a week and this laptop is not what i've expected at all.
First the screen is pixelating the images and videos. I ran the same movie on a Samsung laptop (which has same resolution) and also connected my Dell with the TV to compare the screens. The difference was so obvious. My Dell is pixelating the videos and images. Also, there is problem (figured it out by comparing the 3 screens). When there is scene played in dark conditions, the image is simply absolute black. The actors shadows moving around are not apparent (and the fame video file runs perfect on the other two screens). And when i played with contrast and brightness till the videos became (stupidly) bright, the dark scene are still abnormally black. As if the pixels that should be dark and the pixels around them just turned off.
Second, it's overheating. I ran the laptop on the balanced power plan while just browsing on wifi and the CPU temperature (according to My Dell) is 70-72 celsius just after 30 mins from turning on the laptop. and when i am installing any software or copying files from the portable HarDisk it reaches 90 degrees. I am having it on a flat desk. Also, it's not just the processor that's hot, the outside case is extremely hot too. Like it burns when i tried to have the laptop on my lap. Not to mention that the fans are running at full speed and extremely annoying. And i am even more annoyed knowing that they are not even cooling the laptop down.
Third, the battery works for max 3 hours on the balanced power plan and 4 on the power saver plan with just browsing on wifi. Now Dell claims that the battery lasts for 11 hours and i know it's marketing <ADMIN NOTE: Substitute character removed as per TOU> . But i thought it would at least survive for 6 hours with normal usage on the balanced power plan. I am sorry but if the current lifetime of my battery is normal, then DELL is lying and misleading it's customers by it's false claims in the ads.
There is something terribly wrong with my laptop and this is my first purchase from Dell and it will be the last unless the technical support people (thankfully) save me. Please help. I've updated the Bios, two graphics drivers, audio driver, and the chipset. Still no change in any of the previous mentioned problems
Thanks,
Hani
