I received a (certified refurbished) XPS 13 9350 QHD two days ago.

On white backgrounds the bottom left corner of the screen (the whole area I mean, not just the corner) looks a bit warmer (yellowish) when compared with the other parts of the screen, like top left or center.
I can see it better when there is some text on the screen e.g. while looking at the search results on google. Just to be clear, this is not super noticeable, I can see it quite easily but a colleague of mine could not see it very clearly.

This is very hard to capture on photo so I ran the screen uniformity test in displaycal (with a spyder5) a few times, screen backlight at 100%, while the laptop was plugged to the power supply.

Link to report: http://i.imgur.com/sabTTWP.png

The test seems to confirm a big swing in color temperature (600K difference) between top and bottom left, but also the brighness/luminance seems to be quite low and non-uniform as well!

Are these values normal? I've seen measurements around the web showing higher values for this model (like 280-300 cd/m^2), but in my case it seems to range from 210 (top left) to 145 (bottom right).

Another question, is the Content Adaptive Backlight Control off by default in the QHD version? Do I have some way to know that for sure? When I tried switching between bright and dark images I couldn't spot any change in brightness.

Hi, I am using XPS 13 9350 variant for the last few days, However suddenly from today, sleep mode is not wokring, I turned down the lid and put the laptop in backpack. After two hours, when I took it out, it was extremely overheated as didnt went to sleep. I tried manually putting it to sleep, no luck, From power options it is already set to go to sleep when lid is off. When manually giving sleep mode, it turns down for 1 second and comes back again. What is the solution to this ? Feedback is much appreciated.Thanks in advance.

When I plug in the ethernet adaptecr, the network connections comes and goes, it never stays long enough for me to even run a diagnostic.  I have updated the driver for the USB- C  and the Anker USB-C to 3-port USB 3.0 hub with Ethernet adapter.

Does anyone have any other suggestions?

Hello everybody, 

I have a problem with a fan of my 15R SE 7520 Dell Inspiron. Generally a fan is loud. But sometimes it becomes very loud and then quieter again (but not as quiet as it was at the beginning I bought a laptop 3 years ago). It is very irritating as you can imagine. But, in addition to that hot air is coming out of the fan. 3 weeks ago I went to PC Repair and they cleaned a fan as well as CPU Heatsink and exchanged CPU Thermopaste. It did not last long and it is as loud as before again.

Should I exchange the whole fan and CPU Heatsink unit or is something different is broken in my laptop. 

Hope anyone can help me.

When I connect my Ethernet cable to my laptop, only some websites work and only some applications work. I'm not sure what is causing this problem but when I disconnect my ethernet cable everything works fine.

unbelievable - my 5-year old intel i7 n7110 cannot be upgraded to windows 10, so it's now obsolete www.dell.com/.../SLN297954. its not that old - i have an hp from 2007 thats running windows 10 fine. Coupled with the second-generation venue pro tablet hardware fiascos and price gouging, it's clear Dell is no longer customer or quality-focused. i am working through my last Dell products. Thanks for everything and nothing Dell.

I just bought a new Evo 850 mSata drive for my Dell M4500 Laptop. The Evo supports hardware encryption, and I would like to protect it via ATA password (NOT via Bitlocker). Unfortunately, I am facing 3 problems:

#1 The ATA password doesn't allow for special characters. Which is odd, because according to DELL's support article here, the problem has been solved some time ago:

www.dell.com/.../EN

Granted, the article applied to the E-Series, but I own an E6500 as well, upgraded it to the latest A29 firmware and, sure enough, it doesn't accept special characters either. What am I missing?

#2 After setting the SATA controller to AHCI and installing Windows in UEFI mode, the option to set an ATA password is mysteriously GONE from the BIOS (it is only available with Legacy BIOS, or with UEFI + ATA mode). After googling around, I dug up this old thread:

en.community.dell.com/.../19395511

I would hate to believe that that DELL simply "solved" this by removing the entire option from BIOS, rather than fixing the underlying issue - but then again, if that is indeed the case, I'd at least like to know about it so I can move on.

#3 I am one of those who would like to encrypt their data with the purpose of actually keeping others from accessing it. From what I have read, that isn't as easy as it seems, because even after specifying a password for my HDD access, it seems like Dell is still providing various backdoors so my data can be accessed without my password, and these aren't properly documented. Therefore, I would need some sort of walkthrough so I can make sure my data is actually safe.

My concerns include, but are not limited to, the two following issues:
- I read it's possible to override the HDD password with some sort of master password. This leads to the conclusion that the Dell BIOS must somehow know my HDD password and store it somewhere outside of the HDD, because otherwise, it wouldn't be possible to unlock the HD without actually entering the password.
- Dell also seems to offer some kind of way to overcome the HD encryption by contacting Dell support. It seems like this can be turned off by enabling the "Secure Erase" option in BIOS (i.e. disk will be automatically erased if that recovery password is entered), but that still raises the question how the option to fully recover data from an encrypted HD is possible in the first place, when all that should really exist from a security perspective is a one-way hash that is stored on the encrypted drive itself. Details would be highly appreciated!

After spitting water on my keyboard in Dell Vostro 1320, I need to replace it.

My old keyboard layout was as following:

 [url=http://obrazki.elektroda.pl/5770746700_1457786109.jpg][img]obrazki.elektroda.pl/5770746700_1457786109_thumb.jpg[/img][/url] 

However, I cannot find any new keyboard to buy which looks like this. I can buy ones with longer Left Shift and smaller Enter or one with longer Left Shift and also big enter:

[url=http://obrazki.elektroda.pl/9761146500_1457786280.jpg][img]obrazki.elektroda.pl/9761146500_1457786280_thumb.jpg[/img][/url]

The second one, which I would like to buy has diffrent placement of some keys - for example: Home and End. Will these keys be available in Windows XP in the same place as in old keyboard?

I own a Dell Precision M4600 with a Intel i7-2920XM CPU w/ 32GB RAM

my m4500 allowed me to OC the cpu using the intel provided XTU utility, but the M4600 does not.  After searching the internet, it appears DELL blocks this feature in the BIOS.  Why offer the Intel Extreme Series of CPUs for this machine when other CPUs at a lower price point run at the same exact settings as my extreme cpu if dell is going to block the OC feature Intel gave us in the extreme series?

I have been having these issues since the laptop was under warranty, but could not get any help from Dell. Now it is having a serious issue and I am not sure what is going on. 

The laptop will not not power on with the power button but comes on whenever I plug the charger in. It will come on and I'll see the DELL splash screen with the options for F12 and F2 but then it instantly powers off. I am at my wits end. Last night, I reseated the memory and HDD and it came on with no issues at all. I was able to uninstall apps, add apps, update the PC, go anywhere online, no problem at all and I thought it was fixed. This morning, it is doing the exact same thing.

If I power it on with the battery removed, I get a loud beep and it shuts off. I am leaning toward a power issue of some sort, whether it is the ac adapter or power button or battery ... no clue.

Can anyone help me out? The warranty was over in December, I have 2 identical laptops purchased at the same time. When my wife gets bored, I'll try her battery.

Hi there- huge issue with my 2013 alienware 14 laptop going into "configuring computer" mode without warning often during an important presentation. The delay while it is in this mode is huge- often 10 minutes or more. Unacceptable that you can't delay this mode until presentation over. how do I rectify this issue?

EVERY time I start up, I have to do a hard shut down and wait a few minutes and turn the laptop back on.  It takes up to 5 minutes sometimes for it to load and go to password screen.  This has happened since loading Windows 10. Why is it doing this and how do I correct it?  I am not a techy person so simple instructions are appreciated.

Thank you,

LLong

My screen on this laptop had gone virtually dark, in the right light you could faintly see the screen being active. Without the availability of the screen, I utilized the SVGA option output to a flat screen tv which worked for months! Then that stopped, yet you can see and hear the hard drive working as if all in the world is right…. I promptly replaced the graphics card!  THAT DID NOTHING FOR THE SCREEN OR SVGA OUTPUT!!!  3 years ago I replaced the mainboard which worked awesomely. Now I'm stumped - I truly love this little machine, what am I overlooking?! Can someone shed some light on this scenario?!

Thanks,

Craig
