Power Surges using Expansion plate with Pi-Top Screen

Hi Everyone,

I am making a robot class and it was all going well until this morning.
The problem is that as soon as I start the code up, the screen goes white and interference appears (oddly at the same frequency as the servo jitter). The Pi-Top only recovers on a hard restart after which the screen has a ghostly white boarder around it for a little while.

The evidence would point to a power regulation issue; however, the fact that it worked well until now is strange.
Does anyone have any suggestions?

Hi,

to anyone who is interested, I believe the issue is one of Firmware. I detached the Servos and it seemed to work fine. Which is not ideal.
