Dell :: Up And Downgrading Your 1645 BIOS

Jan 14, 2010

After a development version of the BIOS for the Studio XPS 1645 turned up, some people were concerned about reverting back to an older BIOS after flashing the X29 version. To solve this problem I extracted the WinPhlash utility from Dell's BIOS package and modified the settings.

Now you have several options:

- Simply backup your existing BIUOS
- Upgrade to any version you like
- Downgrade to any version you like

I compiled a package that contains the following BIOS versions:

A01, A02, A03, X29 and A05, A07, A08

This is as far as I know the order in which they were released. The X29 version was never officially released.

Just to be clear: I did not change anything to the actual BIOS files, just to the WinPhlash program settings. These are original, untouched Dell BIOS files, and the same program Dell uses to force-flash your laptop. I just changed a few settings (allowing us a choice of options).

Disclaimer:
I cannot and will not assume responibility of somehow your laptop is bricked during the flashing process. This can happen with Dells own updat packages as well. I myself have used the tool in my package, and others have too, with success. This is however no guarantee for succes.

Please also note that I do not have either a 1647 or a 1340, so I cannot test these files. The theory behind updating the BIOS is the same for all these machines, and the 1340 packages appear to use the same WinPlash64 tool.

The packages can be found here:

20100327_Dell_Studio_XPS_Bios_Tools.zip This package contains the flash tools and the crisis recovery bits.

I have put the different BIOSes in their own packages:

20100327_SXPS_1645_BIOS.zip contains the BIOS files for the 1645, including the latest A08.

20100327_SXPS_1647_BIOS.zip contains the BIOS files for the 1647, including the latest A05.

20100327_SXPS_1340_BIOS.zip contains the BIOS files for the 1340, including the latest A11. The BIOS files for the 1340 seem to be smaller (about 2Mb vs 5Mb) than the 1645/1647 files.


UPDATE: I added the A06 version to the package. Also included Andrew's crisis recovery kit (see this thread for details). I have moved the package to my own server.

UPDATE: A07 is now also included

UPDATE: A08 is now included, and added packages for 1647 and 1340.

Dell :: Xps 1645 I7 A07 Bios &; Speaker Problem! Solved!

Feb 16, 2010

Just thought I'd post some info on what I just went through. Ever since A06 bios release I was having internet connection issues (slow!) and a speaker problem. When I logged off, I got a message saying " waiting for logoff sound" and had to click the force restart/shutdown prompt. Then I installed A07 bios and after playing a mp3 file with windows media player and then restarting, I would have no sound at all!. I had to shutdown, wait a few minutes and restart and sound would come back, weird?

Anyway, I decided to try and solve these issues, so I uninstalled the IDT audio & driver and reinstalled from Dell download site hoping it was just a bad install. BAD MOVE, now my sound really went bad! All sounds played through only one speaker AND it was really muffled sounding. I tried everything to fix this with no luck until I rolled back to A03 bios and ta da, sound was normal again, no issues whatsoever PLUS, my internet connection improved significantly!

Now I am hesitent to update to either the a06 or a07 bios since machine is running better tha n ever on a03. My uneducated opinion is you need to run any updates released prior to a06 or a07 bios before you install these updates.

In conclusion, if you are having issues like me, roll back to A03 bios, reinstall or update drivers, problem solved.

Dell :: Warning About Studio XPS 1647 BIOS And 1645

Dec 5, 2009

today I bricked my new 1645 when I was examing the BIOS for the 1647. The BIOS release 1647_A00.exe released this month automatically begins flashing on an 1645

and does not seem to check compatibility or confirm with the user before it updates.

The BIOS is completely incompatible with the 1645 to say the least, so be very careful if you download it on to a non-1647 system.

Dell is building a new system due to this really sad event. Rip XPS 1645 - December 5th 2009.

Dell :: M1530disadvantages To Downgrading To XP

Jul 22, 2008

I have been doing some heavy 3D graphics work and found that if I turn off all the visual cr@p, it makes the machine run about twice as fast on these intensive processes.

I have been wanting to run another piece of 3D software that is not Vista compatible (Autodesk AliasStudio) and after I installed it, discovered it definitely doesn't run on Vista.

I don't see any dis-advantage to downgrading to XP. I have a spare copy (XP Pro Full OEM) laying around that I had recently loaded on the dead laptop my M1530 replaced. Legit serial and everything.

So do I lose anything by going back to XP? I'm mostly running 2D and 3D apps and occasionally games. XP could only improve performance, correct? Is there anything in Vista that makes it worth keeping?

Dell :: Downgrading E6500 For Less Fan Noise

Nov 30, 2008

The fan starts after a few minutes when the machine has booted. The fan will start even if I only run simple HTML-webpages etc. Afterwards it never stops but keeps running relatively fast (and noisy).

My current config is:

* P8600(2.40,1066MHz,3MB)
* NVIDIA Quadro NVS 160M
* 250GB serial ATA HDD 7200RPM (Free Fall Sensor) (Seagate ST9250421ASG)
* Intel WiFi Link 5300 (802.11 a/b/g/n 3X3) 1/2 MiniCard
* Dell Wireless 370 Bluetooth
* Primary 6-cell 54W/HR LI-ION
* 15.4in Wide Screen WXGA+ (1440x900) with LED backlit
* Windows Vista Ultimate to XP Pro SP3 Downgrade SP1 with XP SP3
(Running XP currently on the machine)

Since I don't play games much and generally don't run 3D-software it was maybe a mistake to buy the E6500 with the dedicated NVIDIA-card, but I figured it was a nice feature to have in the future if I needed it.

I've tried various software to reduce the fan noise without much luck. Currently I'm considering returning the E6500 for a downgraded version without the NVIDIA-card, a lower clocked CPU and a slower HDD.

I'm considering:

* P8400(2.26,1066MHz,3MB)
* 250GB serial ATA HDD 5400RPM
* Mobile Intelģ Graphics Media Accelerator X4500HD

1) Does anyone for sure know if the fan will run slower or maybe not at all if the E6500 is equiped with the Intel X4500HD instead of the Quadro NVS 160M when I surf webpages etc. and don't run GPU-intense software?

2) Will the fan run slower with a 2.26 GHz P8400 instead of a 2.40 GHz P8600?

3) Will a 5200 RPM HDD generally generate less heat in the system vs. a 7200 RPM HDD? (and hence generate less fan noise?)

4) I would really like to know how the BIOS determines how fast the fan should run? Is it dertermined from the overall system-temperature? The CPU-temp? or the GPU-temp? HDD-temp? Maybe an average of these?

Right now the fan has run relatively fast (docked) for about an hour. According to PC Wizard 2008 the temperatures are:

- ACPI Thermal Zone: 31.5 Celcius
- Core 1: 25 C
- Core 2: 26 C
- GPU: 49 C
- HDD: 38 C
- Processor(s) activity: 1-3%

I have the fan-noise issue whenever the machine is docked or not. I like the E-port Plus very much, a digital S/PDIF-audio out would have been nice though. I hope I can use the E-port Plus with the integrated Intel X4500HD if I decide to downgrade. Dual-view is a must for me.

5) I'm not sure if DELL at all will exchange my E6500 for a downgraded version. Does anyone have experience returning DELLs when asking for a downgrade? My argument is to much noise from the fan to my taste, but I don't think DELL will buy this if there's no problem with the machine, so I probably will have to pay for the return of the first machine as well as freight for the new machine. It's quite expensive here in Denmark. Returns cost about $125 and Dell will pick up the machine, the only way to return here afaik. I have 3 year International Next Business Day On-site Response, but probably of not much use if the machine isn't broken or don't need repair.

I nice side-effect from downgrading to a slower system though, will be longer battery-life, but my ultimate goal is less noise.

Dell :: Downgrading From Vista64 To XP32/64 For Dummies

Sep 21, 2009

My dell studio 1555 has finally arrived with Vista Home SP1 64 bit and I'm absolutely hating it. I haven't installed crap on it and 1.5GB of my 4GB ram always remains under use. Don't know about the processor but that too I bet isn't loving the vista experience. Windows 7 is an option but prefer XP. I am pretty much sure XP will run faster and games will perform better eventually.

THE PROBLEM: I have NO F'ING CLUE WHERE TO BEGIN. I want to remove Vista completely and install XP. Is there a XP64 bit version? Because I hear downgrading to 32bit will cause driver issues. I've formatted/removed and re-installed XP on a laptop million times before but never have I went from 64 to 32 bit.. Is it possible? Could someone please show me a tutorial on how to get that done?

Acer :: Downgrading To XP

Mar 11, 2009

my laptop is an Acer I assumed I could just drop the question here. So, I got an Extensa 4630-4922 and it comes with -sigh- Vista. You all know how problematic is Vista, and just the UAC ticks me off to the point of smashing the laptop on the floor. After thinking about it for a while I made up my mind and decided to downgrade to XP. Now, the thing is that I have no idea how to do it. I downloaded a copy of XP off the internet and I don't know what to do with it, and most importantly I don't know where to get the necessary drivers to make XP function. So, I just want to know if there is any guide, preferably a step-by-step one, that can guide me through the installation and set-up of XP on my laptop?

Can he downgrade the OS to Windows 7(64Bit)? as he has some issues with certain software, which according to the developers won't work on Windows 8. Will the warranty be void if the system is formatted and Windows 7 is installed.  Is there any option to go in for a dual boot with Windows 8 and Windows 7.  As per the support center, they do not recommend dual booting on a Windows 8 system.

Acer :: Downgrading 7735Z From Vista To XP

Sep 12, 2009

I've just got an Aspire 7735z, which came with Vista. I plan to use the machine for music software. Another machine I got a while back also had Vista and I had problems getting the software to work, so I eventually gave up and installed XP. Since then it's been working perfectly.

I planned to do the same with my 7735, but I get the BSOD when I boot with the XP disc.

The research I've done (and understand) suggests that I need the SATA drivers on the XP disc. I've spent a long time trying to find SATA drivers for the 7735z but I'm more confused than ever.

HP Envy 17-g0721av OS/Software :: Downgrading From 8.1 To Windows 7?

I am loading up Windows 7 on my new HP Envy 17 laptop. Naturally, we are missing all kinds of drivers.
 
However, I still need to find
 
-Ethernet Controller (tried a few here but didn't work)
-Network Controller (same here haven't found the right one yet)
-PCI Simple Simple Communications Controller
-Universal Serial Bus Controller (USB) Controller ( tried a few here too)
 
 Then I have two unknown devices still ; probably the camera and the fingerprint scanner.
 
I understand that HP directly is not supporting this downgrade. I am not liking windows 8.1 so I want to go back to Windows 7. I have the base system installed and as I said I did find a few drivers but not all.

Sony :: Downgrading To XP And Brightness Settings For Newer Models

Mar 25, 2009

I've been busy downgrading my FW31ZJ (european model) to windows XP SP3.

I have found and installed the drivers for all components and things went smoothly, up until the point where I wanted to get my Fn-keys working.

This is where I got stuck initially and after much forum lurking I found the right Sony utilities to install, the order to install them in and so on (it is all on this forum).

Basicly you need the following components for your machine.

- Sony Firmware Extension Parser driver
- Sony Programmable I/O Controller driver
- Sony Shared Library
- Sony Utility DLL
- Sony Utility Settings
- Vaio Event Service

You also might have to copy the VESConfig.ini from the original Vista install.

I read here that for most this has worked well and offered full fn-keys functionality under XP. Unfortunately I'm not of you...

HP/Compaq :: Downgrading Windows Vista To XP On Mynotebook DV2799EA

Mar 27, 2009

I read a subject about downgrading vista to XP here which is quite helpful and the bewlow link is the subject, but I think this sort of downgrade does not have a straightforward process to do it and get rid of all the frustration you will face, therefore; you always get a problem which is different from some one else.

DV2799ea - How to install XP and all drivers (Yes it is possible)

I have followed the above link and managed to almost install winXP but not completely yet, I have managed to to install the SATA drive from a USB floppy disk just to enable me to go ahead installing the XP, but during the xp installation process it also asks for the Intel Matrix Storage Manager driver which I have it and have all the necessary drivers, and this is where I have been stacked because I don't know how to instal this driver, because obviously it's not possible to use flopy disk to load this driver as it's more than a few MBs, I put it on a USB flash drive and it did not detect it, I even copied it into a blank disk and inserted it into the CD ROM, but still does not pull it and detects nothing, so I don't really know how to load this drive and the rest of the drives, because it does not give me any other options apart from F3=QUITE ENTER=CONTINUE.

Dell :: XPS 1645 Vs. MBP 15.4''

Dec 27, 2009

I'm currently deciding whether to buy the XPS 1645, 6GB RAM, i7, 500GB model of the XPS.

Or a refurbished MBP for the same price. (The one with 256MB DDR3 VRAM)

My main focus is video editing in HD. I've been using Windows 7 and OSX so am familiar with both systems.

What it comes down too right now is the build quality and the potential out of both machines.

I've read numerous reports of "Heat" problems from the XPS1645 which kinda scares me from buying it, however the 1080p and i7 kinda interest me.

Dell :: No Bluetooth 1645

Mar 28, 2010

All of the sudden, bluetooth stopped working on my laptop.

I installed the Dell driver when I first got the computer and everything was going fine. I was listening to music through some blue-tooth headphones this morning, when suddenly they unpaired.

Now, the BT light is on on the front of the computer, but the icon disappeared from the task bar. I tried reinstalling the driver, but got hung up when it asked to turn on blue-tooth with wireless button. The button doesn't do anything for turning on/off bluetooth that I can tell.

So now I'm stuck.

In Device Manager, there is no bluetooth 370 card. But I do have errors in the USB category and the "other devices" category.
