Dell :: UEFI Firmware For XPS 15 (L501X)
Aug 28, 2012
Many of us have brought Dell XPS 15s (L501X) an year ago - they are working great.
However all recent laptops now are coming with UEFI as default, with a legacy fallback option.
I believe current bios (A08) is actually a locked version of Phoenix Tiano Core UEFI.
Does dell have any update or is at least planning to launch one soon?
We need it for full functionality of Windows 8 and get it boot from gpt..., otherwise l501x is a powerful enough machine with i7 & a hot nvidia gpu.

Yesterday I flashed the firmware of my XPS L702X to version A19, which enabled UEFI boot mode. I decided to go ahead and try to install Windows 7 in UEFI mode on a GPT disk. Installation succeeded, booting failed however. Then I read a message on the web from someone who succesfully installed Windows 8 on the same machine in UEFI boot mode on a GPT disk. So I decided to try Windows 8 instead. Installation failed. Using the recovery menu from the Windows 8 installation media, I wanted to try and see how far installation had come and more or less accidentally selected in some "Advanced options" menu to reboot to my USB flash drive (where the Windows 8 files were on). Rebooted fine. Then I shutdown, using the regular option.
When I turned on my machine again, I found out that pressing either F2 or F12, for the firmware setup and the boot menu, respectively, didn't work anymore. The firmware recognised my input, as the text in the lower right of the Dell splash screen became lighter, but instead of entering setup or the boot menu went straight ahead to boot my existing and working Windows 7 installation on my first (MBR) hard drive instead.
So, in short, I am locked out of setup and the boot menu. I have already tried reflashing the firmware, but without any luck. What to do now?

I have a HP 2000-2b19wm laptop. I bought this system. It came with Windows 8. After I got it I completely got rid of Windows 8 and IMHO upgraded to Windows 7 Ultimate. I deleted all partitions and let 7 configure the hard drive the way it wanted, got the drivers and so on and so forth. (not worried about warrenty, I can handel most hardware repairs and software fixes).
I looked to see if there was a new BIOS available and there was, However I also noticed that there are two things called HP UEFI Support Environment and HP Unified Extensible Firmware Interface (UEFI) Support Environment. I know they have to do with Diagnostics and recovering from a bad BIOS flash.Do I install HP UEFI Support Environment or HP Unified Extensible Firmware Interface (UEFI) Support Environment?

Dell XPS L501X USB Ports not working properly. My USB 2 port work intermittently and my USB 3 port doesn't seem to work at all.
In November I installed Windows 8 Pro 64 bit on a new Crucial CRM4256SSD 256GB m4 Solid State Drive. Everything seems to be working except the USB Ports. I know my laptop is an unsupported Windows 8 system. What USB drivers I need to install to get them working correctly.

The last few days I've been trying to replace the 2x 2gb RAM in my XPS 15 (L501X) December 2010 laptop by 2x 4gb (Corsair CMSO8GX3M2A1333C9).
This should be possible based on the processor (Intel 460M) and the chipset, but somehow it isn't. Both with Windows 7 and Windows 8 my laptop just won't boot. Both give an error just after the Windows logo appears. Replaced it with the old 2x 2gb and it boots normally.
Loaded BIOS defaults, didn't work. Erased CMOS by removing the battery, didn't work either. BIOS is updated to latest W8 version.
Also with just 1x 4gb in one slot, the problem stays the same: laptop doesn't boot. (Also tried for the other one of course to make sure the problem is not that one of them is broken.)

My XPS L501x does not accept the 130W charger from Dell.
The original charger (90W) was broken, so I bought a new 130W charger (Art-Nr. 450-12071).
With this 130W charger connected, the BIOS says "Unknow device installed".
When I use an old 60W charger (Inspiron 6000) then the BIOS says something about a "60W AC ..."
I have already installed the current BIOS version A08 !
So, what can I do to repair my system. The L501x will not not recharge the battery with any of the chargers.

I have a brand new Dell XPS with Model : L501X purchased in Malaysia hand carried to Philippines about 2 weeks ago.
Upon receiving I have noticed that a Blue Screen appears with nvlddmkm.sys error every time I play a video initially stored in the laptop hard drive or via youtube.
I have also noticed there were two video drivers installed which where Intel HD graphics and Geforce GT 420M drivers. I installed an updated GT 420M driver through driver downloads in dell support. Unfortunately it did not resolve the issue.
To relieve my doubts of driver conflicts, I have freshly installed a Windows 7 home premium but BSOD still keeps on occurring.
I am currently running this computer using only one video driver (Intel HD Graphics), I want to run this computer using Nvidia Geforce GT 420M.
How am I gonna do that without having BSOD recurring?
Is it also normal to hear some frequently very mild ticking sound coming from the right side of the keyboard and mildly grounding sting on the plastic aluminum colored frame around the keyboard?
BTW, here are some hardware info :
Model : L501X
Processor : Core i5
Ram : 4 Gb
Hdd : 500 Gb
VCard : Nvidia Geforce GT 420M - 1 Gb

I've just changed the hard drive from original to an SSD (cloned image) and changed nothing else.I've put it back together but when I press the Power button, nothing happens at all.
The battery shows fully charged, but there seems to be no power going to the system itself. When I plug in the power adapter, the light comes on for 1s then shuts off (I suspect that's just because the battery is charged) Is there a power reset somewhere if the battery has been out for a few days?

I'm having the seemingly all-too-common issue charging my laptop. I'm trying to update the BIOS bus as the battery is below 10%, it throws an error.
Upgrading from DOS doesn't work either as the updater cannot be run in DOS mode. I've tried all the usual stuff (reseating, etc)
The laptop is the XPS 15 (L501X).

My laptop is refusing to accept the charger cable so I cannot recharge the battery or power up the laptop. The original charger broke but I have tried a new Dell charger and it will not work.

My XPS L501X laptop shuts off completely and without warning. What happens is the cursor freezes. The computer does not respond to anything. After about 15 to 60 seconds, the screen goes black and it completely powers down in an instant. It does not restart on its own.
After it shuts down I can re-boot, but sometimes is shuts off during re-boot. Other times it runs for 5 minutes or so. Usually it acts this way for a day or two, then it's "OK" for a week or so before it starts acting up again.
I have run Dell diagnostics and found no problems. I have taken it to the local computer shop. They ran diagnostics and found nothing wrong and were not able to get it to shut down. Yet when I brought it home, it shut down on me within the first hour of use. It seems to run longer in safe mode, but I did have it shut off unexpectedly today while it was in safe mode.
I suspected there might be a problem with my video card as it seemed to be worse when I had an external monitor hooked up to it. Then I ran it for several weeks without the external monitor and it seemed to be OK. Until today when it started shutting down again with no external monitor attached.
This has been an excellent computer until this started happening about 6 months ago. I"m on the verge of giving up and buying a desktop (another laptop like this one is just too expensive). My laptop is out of warranty.

L501X, working fine until this morning when I was unable to connect to the internet via my wireless connection. Two other laptops can connect as normal. If I hardwire the laptop the connection comes back. When I looked further into this I saw that the wifi was turned off. The problem is that the button in the Windows Mobility Center to turn the wifi on is greyed out and so I'm unable to turn it back on.

I have the Dell XPS L501x and am now getting a failed message when the SMART Short Self Test is run. The message says:
"Your drive indicates that a failure may be imminent. Backup all important files and replace drive."
The hard drive is SAMSUNG HM640JJ.
A couple of questiions please:
1. I take if that this is a legitimate error message as opposed to some system glitch.
2. If I buy another SAMSUNG HM640JJ drive how can transfer the data from the old to the new.

I recently purchased a new XPS15 laptop. Everything works fine so far except I am having problems with the USB ports. I have tried multiple flash drives including some with activity lights. None of the drives have been found by windows and there are no other hardware problems. The drives with activity lights just flash continuously.
I have checked online and can't find any newer drivers to try and Dell PC Checkup finds no problems.

The battery light on my XPS is blinking all the time (orange 4 times, white 1 time).
I have updated BIOS, run PSA Diagnostics and Dell PC Diagnostics and nothing appears to be bad. But the problem is still here.

I have a screen problem on my Laptop, on start-up it shows a white screen with black lines (Picture below) only happens once every 5-10 start-ups. Only happens for 5-10 Secs & sorts itself out before it boots up.
Other time it happens is when I'm using the internet, the screen just sticks, but then when I move the screen, it stops.

I have installed new Seagate firmware DE 17 for HDD with 7200.3 RPM and WEI drop down from 5,9 to 5.8
But HD tune reports still the same tests results.
Do u think that this firmware could cause performance digression.

I have an E4200 with the standard SSD. CrystalDiskInfo shows it as a Samsung SSD Thin uSATA 64GB M running firmware VAM05D1Q.
Seeing that Windows 7 has been out for a little while now and TRIM support is showing up on more and more SSDs, I was looking for a firmware update for my SSD. Anyone seen one?

I tried installing the R206231 Firmware update from Dell for the Seagate drives listed on the support site and it would not complete. I get an error. I noticed that my firmware is DEA2. Is this a newer firmware than the fix is trying to update to? I noticed that the software is trying to upgrade to DE16.
I own a ST9250421ASG in a E6400.

So I am trying to update the firmware on the DVD drive that came with my e1705, the Philips SDVD8820 (Terrible drive I might add) but the new update (AD20) will NOT let me update it.
Anyone I try to run the executable it tells me.
FwFlash
You don't have administrator right to process.
or NO device is recognized.
I then tried to go to Run as... then chose the following user (selected myself again, w/ password this time) and I got the same error.
Once it loads up, it says
FwFlash3M v5.8
Update F/W to AD20
Can't recognize device!
Did some Google searches on the problem and came across this registry edit that seemed to solve the problem for a couple other people .....
