Editing Dell Precision 5520


== Notes for Installing Linux ==
You will need to disable Secure Boot in the BIOS. Repeatedly press F2 when turning on the laptop to get to the BIOS screen.

During installfest events, we'll use PxE booting (network booting) as an alternative to using so many flash drives/LiveUSB sticks. This will require some special configuration in the BIOS, see [[Installfest_PXE_Server]] for details. You will have to allow legacy boot &amp; decrease thunderbolt security (to unauthenticated access) to get PxE booting over ethernet to work properly. Installation of Linux via UEFI/PxE booting on legacy boot works well for these laptops. You will need Dell's specific ethernet dongle to do PxE booting on them.

The GPU is based on the [https://www.notebookcheck.net/NVIDIA-Quadro-M1200-Benchmarks-and-Specs.207414.0.html Maxwell architecture], which is not fully compatible with the FLOSS nouveau driver. You may need to install the nvidia proprietary driver or the bumblebee driver with nvidia for graphics to work. nouveau may not work well as a daily driver, but it is okay to have running during installation on a Live USB with a Linux distribution on it (it is the default of most distros to include nouveau instead of nvidia).

== Notes for using NVMe drives ==
First, enter the BIOS. When turning on your computer, press the F2 key.

Then:
Click the + next to "System Configuration", then click on "SATA Operations", and change from RAID On to AHCI.

'''NOTE: I have tested booting Linux and Windows (201909 version with June 2020 patches) after changing the setting from RAID On to AHCI, so you can _most likely_ ignore the warning.''' However, the worst case scenario is you may need to reinstall Windows - '''make a backup if you're concerned'''. Please tell us on Telegram if this has happened to you so we can help.

At the bottom-right corner of the screen, click "Apply Changes" and then "OK" (it doesn't matter if the settings are "Custom User Settings" - this only stores your BIOS settings so that you can restore them later if something goes wrong, you can either check it or uncheck it, up to you. You can ALWAYS restore to the default BIOS settings - this checkbox will not change that).

Then click "Exit".

Next, add <code>nvme_load=YES</code> to the end of your kernel parameters. This is covered here: [[HP_ZBook_Studio_G4#Installing_Ubuntu_18.04_LTS_via_Flash_Drive]] (except instead of <code>acpi_osi=! acpi_osi="Windows 2009"</code> you will add <code>nvme_load=YES</code>)

== Bumblebee for battery/power mgmt. ==

Bumblebee increases battery life on Linux by a lot. [https://wiki.archlinux.org/index.php/bumblebee The ArchWiki page] tells you how to install it.

If you accidentally install the nvidia or just vesa (NOT mesa, which is needed) driver (and maybe nouveau too) WITH bumblebee (happened to me on Manjaro Linux in the &quot;Hardware Configuration&quot; part of KDE settings when I got some weird dialog asking me to install vesa to uninstall an nvidia package, I forget what, or I might have just been experimenting), you'll need to uninstall them. In these cases, Linux may not boot to a login screen and you'll need to press Ctrl+Alt+F2 to get a shell (it says tty, that just means a virtual Linux terminal). Login as the root user/enter the root password you have set. You specifically need to install the bumblebee and possibly intel-mesa (?) drivers and uninstall the others using your package manager. See the page at [https://wiki.archlinux.org/index.php/bumblebee the ArchWiki page] for more detailed/better instructions/details on how to install/uninstall bumblebee/get the nvidia/intel drivers themselves back.

== Touchpad scroll gestures, etc ==

(Historical information from March 2018):

<strike>I uninstalled libinput and installed libsynaptics or something to get reverse scrolling/less touchpad force needed (FingerXLow/FingerXHigh, similar to that)  options using a config file. libinput is working on the issue right now.

You can also see if those options are in your distro's mouse settings. KDE is fixing this issue by making the descriptions more detailed/understandable.</strike>

'''UPDATE 4/22/2020:'''

Manjaro Linux still has issues with installing libsynaptics. It tries to remove libsynaptics and install libinput every time I update. I am using libinput even though there is currently no way to fix the trackpad sensitivity.

== Disassembly ==
https://youtube.com/watch?v=D4eCtHLRvVo or https://invidio.us/watch?v=D4eCtHLRvVo

You will need Torx T4 (it might be T3) screws to open most of the base (thanks Dell /s). Here is a link to a kit I use: https://www.amazon.com/Wiha-75965-Precision-Ratchet-65-Piece/dp/B00JQ753W8

The other 2 screws are Phillips head, and most screws inside the computer are also Phillips head.

'''Remember to keep your screws.''' Dell screws are special and you likely cannot replace them with other screws because they have a certain depth/pitch to them that most other screws don't. Another annoying thing.

== Updating the BIOS ==
AlphaCubed recommends updating to v1.18.0 as of 6/13/2020. The reason why is because the latest update includes these changes (according to Dell):

<code>
- Modified battery algorithm to prolong lifespan and minimize risk of swelling.

- Added charger parameter update for battery protection mode.
</code>

You can either use fwupd through your distro's package manager (firmware version information here):

https://fwupd.org/lvfs/devices/com.dell.uefi34578c72.firmware

or by downloading the Windows utility here:

=== lshw dump ===

This gives VERY detailed system information. It can come in handy. For Arch based distros, to install do <code>sudo pacman -S lshw</code> then <code>sudo lshw</code> and copy the output (or redirect it to a file like this: <code>sudo lshw > hwinfo.txt</code> then since it can only be read as root with sudo do <code>chown YOUR_USERNAME:users hwinfo.txt</code>).
