Appears you have to have at least the HDMI cable in to be able to view the menu display. I assume it will work with the USB-C that runs power and display but only when you get your device to actually work with the USB-C cable.

To get Bitlocker to work on this laptop make sure PTT is switched on in the BIOS along with UEFI. Otherwise you can’t use Bitlocker on it.

If you need to make a bootable USB stick for Windows 10 it would then need to be Partition Scheme GPT and Target System UEFI

Using a Dell Precision M4800 on the domain was fine when not on the Dell PR02X E-port plus docking station. As soon as put on the dock, the laptop became sluggish and laggy.

Turns out it’s a power issue. If the dock and laptop aren’t getting enough power, the laptop will be clocked down to run at a lower speed. Confirmed this by unplugging the power to the dock while the laptop was on it (obviously simulates not being on the dock any more but still).

Anyway. Put a big brick Dell power supply on, and works fine.

If you have a Dell Precision 470 they can’t use more than 4GB of RAM because Dell annoyingly put in a setup that requires a RAM Fan be installed. Now this system is old, the fans are rare and are being sold for £150+

Now there maybe a reason for the RAM fan. As this is an old server system maybe Dell assumed the system would be under heavy load and could get hot and unstable without one. Or could of just been a money making scheme as they don’t come with the fan as far as I’m aware.

Anyway. Someone at work uses one as a desktop rig and recently we have to put 16GB in it and couldn’t due to lack of a RAM fan. Got round it by Richard reading this forum post

And creating this jumper switch, simply ripped off from an old machine.

Pins 1 and 3 need to be used, expose the top of the cable

Then twist the ends together

Then tape it up with insulation tape (Richard actually cut the wire down hence looks smaller than above images)

And that’s it

£150+ cut down to £1.19 (cost of the insulation tape).

Seems to work fine. System will be monitored to see if it causes issues or gets overly hot, but should be fine.
