How to Access the BIOS
Press the power button once. Then hold down the Volume Down button until the Dell logo disappears. You don’t need a keyboard – it has an on-screen mouse mapped to the touch screen. Cool, eh?
To access the Advanced settings of the BIOS, follow the instructions through Step 7 below:

Getting Back ~5 Gigabytes of Space by Removing Recovery Partition
The Dell Recovery Partition is essential for restoring your machine should something catastrophic happen. To add insult to injury, Dell often runs out of stock of recovery media, and won’t send you such after a year or two has passed. That’s hit me before, and it’s not fun. So, make sure you’ve backed it up!
Once you’ve backed up that recovery partition, there’s no point in keeping it. Get those gigs back!
NOTE: Make sure you have at least 50% of your battery left for this process. I wouldn’t do this when hitting the lower ends of the battery spectrum.
- Go to All Applications and scroll all the way right to the Dell group. Tap the My Dell application.
- Click Backup, even if it says no backup software is installed.
- Click the Download Local Backup button. This will provide a link to download Dell Backup and Recovery, which you should download and install. Basically, once you click the Download button, select Run and wait for Setup to do its job. This process can take a long time. Even the download appears to be huge. It’s probably downloading the latest recovery data, but that’s just a guess.
- After the software has installed, it will request a restart. So, restart the tablet.
- Go to All Applications and back to the Dell group. Note the new Dell Backup and… option. Tap it.
- Wait a few moments for the cool clock animation to complete, then agree to whatever terms are presented, or not.
- Tap the Reinstall Disks option. This is the equivalent of a Factory Restore partition backup.
- Tap USB Flash Drive, which is probably the only real option you have with this unit. This includes use of the Micro SD card, which is what I used, since I didn’t have a USB adapter handy. If you decide to use an external burner, that’s cool, too. But… why?
- Select your USB drive, or the MicroSD card. I backed up to an 8 GB MicroSD. Dell estimates the backup at 4.03 GB, so 8 GB should suit you just fine.
- Tap Start, then tap Yes when asked if you’re sure about wiping out the USB or MicroSD drive. Of course you’re sure! (right?)
- Wait until it’s done.
- When it’s complete, click OK, and put the backup media in a safe place. I put it in my Venue Pro’s box.
- Go back to Start, then All Programs, then Desktop.
- Hold down on the Start button and select Command Prompt (Admin).
- Type diskpart to launch the Disk Partition manager.
- Type list partition to see the available partitions.
- Type select partition X, where X is the number of the approximately 4 gigabyte recovery partition. On my Venue, it was 6.
- Make sure you see “Partition X is now the selected partition”!!!
- Type delete partition override and hit enter.
- You should be greeting with “DiskPart successfully deleted the selected partition.”
- Type exit to quit DiskPart, then exit again to quit Command Prompt.
- Now that the partition is gone, we need to expand the size of the main partition.
- Open an Explorer window and long press This PC, then select Manage.
- When Computer Management appears, select Disk Management under Storage.
- You should see the 4.64 gigabytes or so we freed up showing as Unallocated.
- Long press your C: drive and select Extend Volume….
- The Extend Volume Wizard appears. Click Next.
- You’ll be asked where the space to extend the volume should come from. Everything should already be filled out to assign the maximum unallocated space. Simply tap Next or adjust as desired and click Next.
- The wizard will confirm the extension settings. Click Finish.
- There you go! Your C: drive is now almost five gigabytes larger!
UPDATE: You can also back up to a USB drive by acquiring a USB OTG, or “On-The-Go”, adapter. Pick one up from Fry’s, SKU number 7582626, here. This will also enable you to use thumb drives and such on your Dell Venue 8 Pro.
Disable the Annoying Backlight
Dell’s power management settings for the backlight are wretched, making the display dim almost all the time. Let’s get around that, shall we?
- Swipe out the charms menu, then select Settings, then Change PC Settings on the bottom.
- Select PC and devices.
- Select Power and sleep.
- Set Adjust my screen brightness automatically to Off.
