**Dell XPS 17 (L702x) - DO NOT FLASH to BIOS A14 - (Updated 1/5 - see post 1)**

Bios A16 on Dell site.

1.Update BIOS and EC to fix AC adapter can't be detected with probability. -Add re-try mechanism between EC and adapter PSID.(Re-try 3 times every 500ms to extend detection time for Adapter plug-in)
2.Disable Div2 spread spectrum for error or failed to copy files from external USB 3.0 devices.

 

Hi,

Does the bios have any issues? I usually install updates as soon as they come out, but after the issues with last dells bios i'm a bit reluctant

 

Yes, there was reported an issue in this thread, but for me it works stable, same as all the previous bios I had - A10, A11, A12, A14 and A16

 

tbh I'm kinda worried that a16 is geared towards the new hardware revision (with the gf116) so am likely just going to stick with A12 to avoid any possible conflicts

 

thanks for your replies. I will stick with A12 too for now.

This is my 1st dell laptop, and honestly I don't like the way they deal with this (disappearing older versions, incompatibilities). I guess i'll have to wait a month or so and see where it goes. If anyone with A12 and the old revision decides to upgrade, please let me know

 

Does the A12 allow for 2 8GB RAM with the non-3D screen? I guess I'm trying to figure out at what BIOS update this because doable.

 

hey iv readed the bios is UEFI capable, and so does hwinfo says

so why hasnt been enabled ? or do i need something ot enable it ?, its also raid capable but i cant find anything about it in bios why ?

 

Hi Bill, I got a xps 17 with a14 and tried everything to flash back to a12, but the error i get is: an unexpected error occurred while running the flash application. please reboot and try again. if the error continues, please contact technical help. application error return: 0x00000207
i googled the error, and they say it is related to the system not recognizing the battery, i deleted the "dellbios" folder in the registry as they say, but still get this error.
I'm unalbe to install any version of nvidia (from dell or nvidia) driver updates on my system. My computer works but most older apps use the intel graphcs instead the nvidia geforce 550m.
can the a12 be installed using a bootable usb with dos? or is it a winap?
Please help me on this.
thanks

 

Ok, I resolved the issue. The problem related to updating the nvidia drivers on dell xps 17 with geforce 550m was my issue from the beginning. Some games wouldn't detect xps original driver, thus running on the intel graphics one, which results in bad gaming experience.
Now, I wasn't able to step back to former bios versions like a11 or a12, I'm stuck with A14, but I was able to advance to a16 with no problems. But that didn't change anything. All dell or nvidia drivers where denied cause of "No compatible hardware detected".
But there is a simple workaround to make nvidia driver 290.36 (get it here NVIDIA DRIVERS 290.36 BETA) work. Just download the driver, install it. Now download nvam.inf.txt at http://forum.notebookreview.com/del...nvidia-will-update-time-goes.html#post8160266.
Paste nvam.inf.txt into C:\NVIDIA\DisplayDriver\290.36\WinVista_Win7_64\International\Display.Driver, rename the original, then rename nvam.inf.txt to nvam.inf
Start the driver setup, it works. The only thing is that you'll get a windows complant about "Can't verify driver origin", but just click on "install anyways" and your done.
Works like a charm on gta 4 and fsx, increased framerate enormeously.
My problem was that the original Nvidia driver shipped with the system didn't get detected at all by the older games. In the settings of FSX it stated "Intel Graphics", thus I only got quite low performance.
Enjoy

 

is theere any ocing for this gt555m ?
