Definitely need to do a cold boot. Shut down the pc and wait, then reboot. FYI, a cold boot often solves many problems. This allows the memory to adequately clear.i had the yellow bang, too. when i first installed, i was on battery and was informed i needed to charge the battery before proceeding, did that and updates installed.
after 3 restarts and system updating messages, it booted and had the yellow bang.
i tried disabling and enabling. i tried rolling back the driver. i tried uninstalling the driver and rescanning for hardware changes.
i tried stopping windows update service and deleting the software distribution folder, so all of the updates could be re-downloaded.
tried it with and without the keyboard.
finally, shut it down, went and did some stuff for 45 minutes, turned it on and no more yellow bang on the sytem aggregate firmware.
so. maybe leaving shut down for a while helps.
You probably need to pair it again.I had a number of problems after the update--especially inability to start screen after sleep--I did a system restore which I assumed got rid of all the updates--that fixed the re-start problem--but now it also knocked my wedge mouse out--cannot be recognized--anyone have a solution to that issue? tx
I had the same situation. If you click properties it will ask for a reboot : See Screenshot :I have downloaded and installed all of the updates, to include the Firmware update. When I look at Device Manager, I see the yellow caution flag under Firmware. Specifically the "Surface Pro System Aggregator Firmware" is flagged. The General tab states that "This device cannot start" .
A quick look at update history shows that this update failed. Have uninstalled, restarted, etc. no solution.
From what I have read there are many way to attempt fixing this and only some of them work and then only some of the time. The same as you I tried all the tricks I could think of. Roll back the driver, uninstall the driver, uninstall and delete the software, depress the on/off switch for 15 seconds, etc. Nothing worked so I just rolled it back to the previous driver and left it that way. This morning after I read your message I went into device manager, firmware, picked the third item down which was no longer called Surface Pro System Aggregator Firmware but just something like "Firmware Resource", and selected update driver, search automatically. In a fraction of a second it said "Update Complete" and I saw the name had been changed to Surface Pro System Aggregator Firmware, and there was no yellow flag. Not content to leave well enough alone and firmly believing that a reboot would bring back the yellow flag, I rebooted. The flag was still gone and the name was still Surface Pro System Aggregator Firmware. So MAYBE I am out of the woods on this one.meant for this to be in the above post. Sorry type cover is to blame, or maybe the operator and not having had enough coffee yet?
After I clicked finish it reset the Surface and gave me a b lack screen saying SURFACE under that "Please wait while we apply a system update." Then the unit rebooted and I was good to go.
