Dell XPS 15 L521X :: Graphics Chip Is No Longer Recognized
Sep 19, 2012
So I updated to Bios A09 hoping it would improve either my Wifi issues, my throttling issues, or my battery life issues.After the A09 update, my nVidia Graphics chip is no longer recognized, and therefore have lost my dual external monitor support. That may improve battery life I guess since the nVidia chip is now worthless and I'm forced to the Intel 4000. Not the change I was hoping for.
Is it possible to revert the A09 bios back to A06? Is this isolated to me, or was it just not QA'd at all by Dell?I worked around the wifi issue with a USB dongle, and am living with the battery life issues by getting less work done on airplane flights.Losing my multi-monitor support is killing my productivity. Also losing my patience with this machine and Dell in general.

the 3650 ATi graphics chip on my Dell studio 17 is on the way out
I have had an offer by a company to reflow it, and install a copper shim

I'm hoping this is in the right area.
I have a Dell Inspiron 9300 It's upgraded about as far as it can go. I use a desktop for the occasional gaming or rendering but this is my daily driver.
The issue. I took it apart the other day to see if my screen hinge could be replaced and to install a DVD burner. Now it no longer recognizes the onboard/integrated keyboard. It still recognizes the touch pad but not the keyboard. I went as far to buy a whole new OEM keyboard. Still nada.

I just went to the Dell US site to configure a 15 Studio laptop and notice when you go to configure the laptop the only choice for graphics is the integrated 4500HD!

Recently purchased the new i7 XPS 13 model (L322X). It's a lovely machine, but I have two problems with it.
Firstly, I can no longer enter the pre-boot setup screens. It did work originally, but now it simply doesn't load. I can still switch between different boot modes (Legacy BIOS mode, UEFI+SecureBoot, UEFI+No-SecureBoot) but I cannot actually get into the setup screens any longer.
If I switch to Legacy BIOS mode, then I do get text on the screen (bottom right) suggesting I can press F2. If I hit the key, the text changes colour slightly to suggest the keypress has been recognised, but then just proceeds to try and boot the machine (which fails as expected as there is no legacy bootloader).
Is there some kind of EFI variable that affects this - perhaps locking me out? I can still use the machine fine, but this is obviously disconcerting.
The second problem is manifested when I enter the Diagnostics utility in the EFI bootloader.
It reports all is well, except the Graphics:
It states:
Error Code: 2000-0332
Validation: 80763
Msg: Video memory - Video memory integrity test discrepancy
Please record the above Error and Validation codes
Further details are:

I have installed a 6gb/s ssd into my l521x; however, I am getting 3gb/s speeds (~250mb/s read and write)
Is there a setting to enable 6gb/s speeds on the l521x?
It appears the l521x has the HM77 chipset which does support 6gb/s throughput ?

Can someone tell me what this chip is? Is it the CPU? I want to buy a thermal pad for it as it's cracked. Btw I replaced the thermal paste under the large heatsink on the left.

I have an out of warranty 15" XPS that will just shut down at random intervals, doesn't seem to be heat related as it will sometimes do it immediately after turning on, doesn't seem to make any difference if its plugged into the mains or on battery either.
Run dell diagnostics at start-up and no problems were found.
Machine will usually turn back on fine, sometimes the battery needs to be disconnected first though...
Other notes:
Currently running Windows 7 64 x and tried with fresh Windows 8 install too (feels more like hardware really)
Currently running the A16 Bios
Fan works correctly...

I rebuilt my new XPS 15 with Windows 7. I didn't build any recovery media before I wiped the hard drive. Where can I download the recovery tools to restore to factory build ?

I have a Dell XPS 15 (L521x) laptop. While gaming my GPU heats up to temperatures ranging from 73 to 77 degrees Celsius (NOTE: This is with a CM Storm SF-19 cooling pad).
My question is how else can I reduce this heat because I know as it gets hotter it throttles back to avoid crashing, thus decreasing performance.
Here are specs of everything:Model - Dell XPS 15 (L521x)OS- Windows 7 64-bitCPU - Intel Core i7-3632QMBIOS - A13 (Up to date)SSD - 128GB (OS is on this, 30GB free)HDD - 1TB (300GB free)RAM - 16GBGPU - Nvidia GT 640MDrivers for EVERYTHING (including my graphics card) are up to date.CM Storm SF-19 Gaming Laptop Cooling Pad with two 140mm Turbine Fans (1200-2600 RPM's, I always keep it at max blast)
Using software program, Open Hardware Monitor (and having my cooling pad on max blast), I have retrieved the following data:~ My CPU idles around 60 degrees Celsius and can max around 70 degrees Celsius~ My GPU idles around 44 degrees Celsius and can max around 77 degrees CelsiusMy room temperature varies from 10-20 degrees Celsius (50-65 degrees Fahrenheit)I had this laptop since July of 2012 and I had just had my motherboard swapped (GPU was integrated), heat sink re-seated, and cleaned of dust (wasn't really any in there). It was under warranty (and still is).

Dell announced, a few weeks ago, a new replacement for the 57XX and 55XX Mobile Broadband MiniPCIe cards that they are installing as integrated WWAN in select notebooks.
The new Dell Wireless 5600 Mobile Broadband card is based on the Qualcomm Gobi chipset, and therefore supports all major NA carriers (CDMA and GSM/HSPA), and all global UMTS/HSPA bands.
As a result, you can theoretically use this one integrated device on AT&T, Verizon, Sprint, O2, Telus, Rogers, Fido, T-Mobile, or any other EVDO or HSPA service globally, just by activating with the provider (CDMA/EVDO) or using the providers SIM card (GSM/HSPA).

I have just purchased an XPS15. I understand that the mSata drive (a Samsung 841 512GB) supports on-chip encryption, however I'm struggling a bit to understand how to enable this. I have read some posts which seem to suggest that it's as simple as going in to the BIOS and configuring the "HDD Password", option in the security section, however this seems just a little too easy (I was expecting to have to create a public/ private keypair or something to that effect).
How to authoritatively confirm whether this is indeed the correct way to configure encryption on the disk? Or is this just a basic BIOS level password which somehow protects the disk simply by virtue of the fact that it won't allow the machine to boot unless the correct password is entered?

I broke it connecting a wrong power adapter and now a need a small piece that is inside ; i think its a MOSFET transitor, and there are two of them in the motherboard (only one is break). In the surface I can read : 4835d X860 . I am searching since some days ago and i can´t find this piece or similar to replace.

I have a DELL XPS L521X running Windows 10 technical preview.
I have been having an issue for a while that the computer automatically resumes from standby at seemingly random times. As of late, it is also staying on indefinitely (or until a low battery event at least), despite my settings in Power Options that specify standby after a given amount of time.
This happens when it is plugged in or not, and is (of course) particularly annoying when it is unplugged and in a case that isn't ventilated.
I have checked the system and application event logs, and don't see the kernel-power event when the system resumed, but I don't see any information on why it did so.
Also worth noting: I checked my LAN and WIFI adapter power management settings, and the "allow this device to wake the computer" box is greyed out.
specifically what hardware or software is causing a resume event? Do you know how to ensure that the computer sleeps after a specified period of time when on battery?

I've got a XPS 15 L521x that was running Windows 7 for weeks with out incident. I decided I'd like to try Windows 8. I installed (after changing Sata to AHCI) without incident. After the install completes I reboot and it crashes. The OS goes to "attempting repairs". I can run a "refresh" of the OS and it will fix the issue and then crash again after a reboot.

I love the hardware design of the XPS 15, except that the touchpad is unusable for scrolling. My old Latitude 6520 at least could use the scroll zones well, but with the buttons on the L521x being part of the touchpad, the horizontal scroll zone impacts button usage and isn't worth it.The big issue is the multi-finger scrolling jumps significantly when lifting fingers. I've tried every version of the driver I could find, and they all have this issue. If you make sure you completely stop scrolling before lifting fingers, then lift one at a time, I can usually avoid the jump, but that take more time than just using the keys to scroll.
Is there a way to either disable horizontal scrolling using scroll zones or fix the 2 finger scrolling to not jump? Except for that issue (and some sporadic wifi issues that my be fixed with newest driver), this laptop would be perfect for me.

The L521x drivers clearly have a problem when any two finger scrolling can cause the document in any program to immediately skip to the very beginning or the very end.
This issue has come up in the thread [URL] .... but that has been incorrectly marked as answered and I'm concerned that the issue will be buried because of that.
Synaptics have released several driver versions since the 16.3.7.0 driver, up to 16.3.8.8, fixing many issues including a BSOD, whereas so far for the L521x we have just had A03 and A04 variants of the same driver (16.3.7.0), neither of which solve this problem.

I currently have a XPS 15 (L521X, Mid 2012) that I use at college, and it's "p" key has been getting harder and harder to press. It's at the point where hitting it does not register any action unless I press down on it. Do I have to open the laptop up/take the key out? And how do I do this?

I found a good deal on an E6400 which is perfect except that it comes with Dell Wireless 1397. I want the Intel 5100 for Linux compatibility, but I'd hate to pass up a good opportunity just because of the wireless chipset.
I have a few E6400s at work, and it looks like the whole underside needs to be unscrewed (and I won't test on them for obvious reasons)?

I tried upgrading my Latitude's RAM using a 2MB chip first in the rear slot, and Win 7 didn't read any additional RAM (showing only 1GB). So I moved the 2MB chip to the MB under the keyboard and now it won't reboot. I tried to put the original RAM chips back in their respective slots (each 1MB RAM) but it still won't boot.
I guess I can't update the BIOS if it won't boot.

I just received my XPS 15 and plan on dual-booting Win 7 and Ubuntu. I'm trying to install both, but I have no disk drive boot option in UEFI mode, only in legacy mode.
How can I boot from a disk using UEFI mode?

I'm in the process of upgrading my L521X/XPS 15 to Windows 8. The A09 BIOS introduced UEFI booting, which I of course intend to use. However, I can't get Windows installed when Smart Response is activated in the BIOS. The installer simply doesn't show any disks - even when loading the correct drivers. Changing to AHCI allows me to install - but of course without the benefit of Smart Response. Now, the question is: is it possible to use pure UEFI and Intel Smart Response Technology on the L521X?

Brand new laptop idles at 55° C, but at least the fans are quiet. Casual web browsing, listening to music, and/or downloading files and cpu temp rises to mid 70° C and the fan starts humming pretty noticeably. If I try to do any gaming, PC hits 85°+ C, fans go crazy, and the laptop starts beeping. I really like this laptop, but I need it to be able to handle my day to day activities.

My computer will (most of the time when a browser is open, it seems to happen most frequently when I'm watching a video) begin making clicking and beeping sounds. I'm able to switch tabs and sound will play from the videos for about 20 seconds. After that the screen will freeze (I won't be able to switch tabs or close anything). I usually try to open task manager, but even that isn't an option. After waiting for my computer to shake itself out of this state, I hard shut down and then reboot. The computer has only "shaken" out of this state 2-3 times in 30 total occurrences.
