Windows 7 upgrade tips for Inspiron 1420

This question has been answered by


I just finished upgrading to Windows 7 64-bit from Vista 32-bit (which came with my machine) on my Inspiron 1420, by using the custom installation from a Windows 7 Home Premium Upgrade disc.  I was kind of intimidated about necessity of 64-bit driver since there is no 64-bit support option on Dell's website.  So having gone through it successfully now, I thought I would share how I did it for those who may be thinking about the upgrade.

Chipset, Audio and 3945abg Wireless:

Although Dell does not list support for 64-bit drivers for the Inspiron 1420 on its driver homepage, there are three drivers on that page that do support both Windows Vista 32-bit and 64-bit.  These drivers are for the Intel Chipset, Sigmatel Audio and the Intel 3945abg wireless card.  Note that the Inspiron 1420 booted fine for the first time after the Win7 OS was installed, and the wireless card and audio were functioning with the Win7 native drivers.  So the Dell drivers are not absolutely necessary.  However, I decided to install the Dell chipset and wireless drivers from the 1420 driver page in case they would be more efficient.

Touchpad and Quickset:

Now, Dell's 1420 driver page does not have 64-bit drivers that may be used for the touchpad, quickset functions (external audio buttons) or video card.  After booting Win7, I found that my touchpad lacked the scroll features and only the mute button for quickset worked.  However, no quickset graphic popped up when the quickset buttons were used either.  Fortunately, Dell provides touchpad and quickset drivers for Windows 7 64-bit for the Inspiron 1545.  I downloaded and installed these drivers with success.  As far as I can tell, the scroll features and external quickset buttons function fully with the 1545 drivers.

Video Card:

Finally, the video card.  I have the NVIDIA 8400M GS.  In the past, I do not believe that the nvidia website offered support for this card.  In any case, there is a Windows 7 64-bit driver on their website that supports this card and worked for me.  Note that the nvidia website recommends updating the bios of the computer to version, A09 (available on Dell's driver page).  I had updated to the newest bios, version A10, and the driver seems to be compatible with this version.

For what it's worth, I also installed 2x2GB (for 4GB total) of DDR2 RAM prior to the install, and the OS recognizes all 4GB.

I hope this helps some other Inspiron users who may be interested in upgrading their OS.  Although I have not used the OS a whole lot yet, the machine seems completely stable and functions well. Good luck!

    I have been using these drivers since a year and they are working great!!


    Please support my idea: More than 4GB RAM support on Inspiron 1420:

  • Nooooooo. I was searching for the Dell Quickset 64 bit version for a while. Dell have the link but it is broken and my emails are ignored. I thought I was lucky but the download link only downloads a small piece of the file making it corrupt.

  • Here you go...a working Dell Quickset for Inspiron 1420 running Windows 7 x64

  • Do you have another link for this file, that link is expired?  I just upgraded and I'm having a hard time getting all the drivers.

  • Suggest me a website where I can upload the drivers permanently. I have been getting a lot of requests off lately.

  • You can try  They have a free upload account.  Thanks for the respond.

  • Have you tried uploading the file yet, Ireally need to get this laptop working correctly?

  • Here is the new link:

  • Thank you very much for uploading.  I can finally get this thing running normally.

  • How much memory does Windows 7 64 bit report with 4gb of physical memory installed?  How much is free?

  • See later post for updated download links to the Dell ftp website.

    What to do is look at each of the Vista 32 bit drivers for you're system and look at the compatibility tab. These will tell you what systems the driver is compatible with. Look for an XPS system or Precision system as they are likely to have 64 bit equivalents which will work. And you already know 64 bit Windows Vista Drivers are going to work with 64 bit Windows 7 (there are a few excepts such as bluetooth, explained later):

    For example Dell Notebook Software R156592.exe

    Inspiron 1420 

    Inspiron 1526 
    Dell Precision Mobile WorkStation M6300 
    Vostro Notebook 1400 
    Vostro Notebook Dell 500 
    XPS M1730 
    XPS M1530 

    Going to the page for the Dell Precision Mobile Work Station M6300 we select Vista 64 bit and get Dell Notebook Software R160842.exe. Note on this compatibility tab it does not mention you're inspiron but it is 99 % likely to work as the 32 bit driver was common for both of them.

    Thats you're first 64 bit driver. Then we proceed to chipset...

    1. Dell Notebook Software R156592.exe (Precision M6300)

    2. Intel Chipset R153997.exe (Precision M6300)

    3. Ricoh Chipset R168331.exe <ADMIN NOTE: Broken link has been removed from this post by Dell> (Precision M6300)

    4. Intel Video R180865.exe (XPS M1330)

    5. nVidia Video R200275.exe (XPS M1330)

    6. Conexant Driver, Utility, Diagnostics R150157.exe  <ADMIN NOTE: Broken link has been removed from this post by Dell> R147123.exe R148605.exe <ADMIN NOTE: Broken link has been removed from this post by Dell> (Precision M6300)

    7. Broadcom Driver, Diagnostics R185840.exe R151335.exe

    8a. Dell 1390 WLAN Mini Card R174292.exe (Inspiron 1420)

    8b. Dell Wireless Except US, Japan R151520.exe (Inspiron 1420)

    8c. Intel Wireless Intel Website

    9. Sigmatel Audio R171786.exe (Inspiron 1420)

    10. Touchpad  R157047.exe (Precision M4300)

    11. Dell Bluetooth 355 R226750 <ADMIN NOTE: Broken link has been removed from this post by Dell> (Bluetooth 370 Driver for Windows 7) - It will work with the 355 card. The Vista driver for the 355 card will crash windows explorer on 7 so this is a better drive.

    12. Webcam R173082.exe <ADMIN NOTE: Broken link has been removed from this post by Dell>  (Inspiron 1420), Skype 4.2 R272748.exe Dell Webcam Software R230103.exe - Note can get later version on skype website but I prefer 4.2

    13. Dell Quickset R182249.exe (Precision M6300)

    14. SATA Drives: Intel Turbo Memory R167146.exe 

    <ADMIN NOTE: Broken link has been removed / replaced from this post by Dell> 

    & R154164.exe (Inspiron 1420)

    15. SATA Drives: Intel Matrix Storage Manager R154198.exe <ADMIN NOTE: Broken link has been removed / replaced from this post by Dell>

    16. Dell Support Centre

    Then there you go, a complete set of drivers for use with Windows 7, 64 bit...

    For best performance ensure that you install Windows 7 Service Pack 1 Standalone and Internet Explorer 9 Standalone before installing the system drivers. Also drivers install in the order listed. windows6.1-KB976932-X86.exe & IE9-Windows7-x64-enu.exe.

    Ensure that you do a clean install and not an upgrade, full instructions for installing Windows 7 are listed in the link below.

    While this complete driver set

    should work, I don't have an Inspiron 1420 and so cnanot test it, if anyone has any problems with any of these drivers let me know and I'll try and find another.

    Finally I am pushing through on Dell Idea Storm for Dell to make downloadable .iso files of Windows that include the latest service packs and builds of internet explorer. I would appreciate if you guys sign up to idea storm to promote the idea (link below). That way the end user can effectively download everything off Dell to do a clean install of windows with optimal performance.

  • Loaded W7x64 onto my 1420, after lots of W7 updates and fiddling around everything seems to work (I have no idea about the modem).  However have one Base System Device with a yellow triangle.  Could that be the modem?  It sounds like the sort of very standard device W7 would include a driver for.

    It's listed as 'PCI bus 3, device 1, function 3'

    Could this be the modem?  Or something else?

    I might actually buy a W7 for this laptop but only if I can be sure all the hardware is OK.  Equally if I decide to sell it it would be useful to be able to say if I managed to load W7 completely successfully.  I haven't wiped the restore bit of the disk so can always put it back to Vista.
