Error 950.10 NVRAM mismatch. how do I fix or
The way that I have found to fix this problem is to replace the logic board but when you do that, this is where the NVRAM mismatch comes in. Once you change the logic you also have to change the display op panel. That is what is giving you this error. You must change logic and op panel at same time and it will not give that error.
My house roof has an
the area of your roof is equal to the base (B) times the hight (H) divided by 2.
A = ( B x H )/ 2 = 120
To get the Perimeter of your roof you need to sum the base plus the sides (S)
So P = B + 2 x S
if you have a slope degree of 30 then
B/2 = cos (30) x S
so P = B + 2 x B / 2 / cos(30)
P = B ( 1 + cos (30) )
we also know that
H = tg (30) x B/2
from this last one we can go back to the Area and get a value for B
120 = ( tg (30) x B / 2 x B) / 2
480 x SQRT(3) = B^2
B = SQRT(480/tg(30))
So:
P = SQRT(480/tg(30)) x ( 1 + cos (30))
tg (30) = 1 / SQRT(3)
cos (30) = SQRT(3)/2
P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

Why my Trifo Emma not powering/starting after press button Reset? The robot vacuum is dead.
Some times this is just the charging dock not communicating with the actual robot vacuum. What surface is the charging dock sitting on? It works best if it is on a hard surface and Not carpet.
Try this. Remove the vacuum from the charging dock and turn it completely Off. Unplug the charging dock from the wall outlet. Check inside the charging dock at the connection point the robot plugs into. Make sure it's clean. Next check the robot itself to make sure the connector on that is also clean.
Everything needs to be completely turned off for at least 5 minutes. This does a 'Soft Reset' on the Robot's electronics. After 5 minutes fit the robot back into the charging dock, gently but firmly making sure it is all the way in place. Next plug the charging dock back into the wall outlet. DON'T turn the robot back on. Walk away from it for an hour to let the charging dock put some charge into the battery in the robot. After that hour turn the robot back on and see if the issue has changed.
Hp 7500a "The following ink cartridges appear to be missing or damaged"
I figured out the problem with my printer. If none of your ink cartridges are detected (missing) then follow the install steps below.
1. Turn on printer
2. After printer declares cartridges missing open the printer and remove the cartridges (advise putting a piece of paper under the cartridges to catch any ink that spills).
3. Turn off the printer (keep the top of the printer open)
4. Turn on the printer (still with the top of the printer open)
5. After the printer declares the cartridges missing again install the cartridges (while the printer is powered on). Close the top of the printer.
6. The printer should begin to cycle the ink into the printer and back out to the ink reservoirs.
7. After the ink cycle the printer should display genuine ink cartridges are installed
8. Make sure paper is in the tray so the printer can perform an alignment.
9. Everything should be ok after that.
