A series of multi-day tests, which included attempts to restart and reconfigure the computer and the backup computer, were not successful, but the information gathered from those activities has led the Hubble team to determine that the possible cause of the problem is in the Power Control Unit (PCU).

Because no ground commands were able to reset the PCU, the Hubble team will be switching over to the backup side of the SI C&DH unit that contains the backup PCU...
The switch will begin Thursday, July 15, and, if successful, it will take several days to completely return the observatory to normal science operations.
The team performed a similar switch in 2008, which allowed Hubble to continue normal science operations...
Send up the Geek Squad they’ll NOT FIX IT
Did you try turning the Hubble Telescope off & on again?
Just send the shuttle up and fix it
Or banging on it.
Or Bugs Bunny. He’s great with gremlins.
I’ve had a theory about the Hubble for a long time. Remember after it first went up, there was some kind of imperfection in the huge mirror that made the images less than perfect? And the fix required a spacewalk and then the images were astounding. I always thought it was odd that (1) they’d send this multi-billion $$$ device up there with a flaw they weren’t aware of, and (2) this flaw to this huge, precise mirror was so easy to fix that it could be done with a spacewalk and the limitations that presents.
So I think they engineered a way to make the images imperfect, so that they could have a spacewalk to “fix” them, showing how important NASA was, when in reality, the fix was right there in the device already.
I think this is the same thing. This issue with the computer will be used to argue that they just have to have a manned flight to go up and replace the computer that failed.
What will NASA do when the backup power control unit fails and there is nothing left? Another repair mission to replace the entire control system? How, with no shuttle? SpaceX Dragon? Branson conduct a flyby and throw a swapout unit at Hubble as he streaks by? Bezos fly his Dr. Evil spacecraft to the telescope and fix it with Amazon private label replacement parts?
Maybe NASA will just return to its primary mission: Muslim outreach.
Oh no, AOC’s Green Energy plan! Hubble is doomed (as are we).
Maybe SpaceX can send a Starship to pick it up and bring it home
Probably the latest Windows 10 update.
Yes they actually did!

Except there is no such vehicle and; even the Shuttle, if it still existed, had some difficulty getting to its very high orbit.
What will NASA do?

De-orbit the Hubble and use the-soon-to-be-launched James Web Telescope
“I think this is the same thing.”

Unless you’re talking about vaccines, then sure!
If you’d like to know what happened:

Did they check to make sure the power cord is plugged into the wall socket?
The “coming out charge” will be kinda steep.
Parts and labor will be only $49.55 if NASA has extended warranty protection.
They may or may not fix it. But they will take all the media from it prior to trying.
We’ll have to wait for the book and movie I guess.
Since it was not taking any commands from the ground it has been difficult to figure out.
