New Firmware -- Overtemp warning
Saw a new message and icon on my mr1100 since updating to the most recent AT&T firmware a week or so ago.
While it's good that the mr1100 now tells you why it is not charging -- due to battery/devi...
Does the Nighthawk MR1100 log somewhere that it had an "Overtemp" warning? Mine is plugged in 24/7 and feeds a SOHO router via Ethernet. How can I tell if the Nighthawk is experiencing this?
The only indication is the front screen, which will say "battery heat mode" plus words that charging is suspended. In this case, the web page indicators are stupidly wrong (see screenshot), because it says "battery charge status - yes" even though it's losing charge.
Will the Nighthawk overheat if you run it plugged in without the battery?
I've only ever seen over temp warning associated with the battery charging status. Though I've never run mine in direct sunlight for hours to see what would happen.
As I and others have commented. For stationary applications, remove the battery entirely, leave the back cover off to aid with cooling (and/or add a small fan) and power the unit with a quality QC2/QC3 power adapter and USB-C cable (I like Anker equipment).
The wall wart that comes with the MR1100 is garbage and not QC2/QC3 capable.
If you want "battry backup" for your stationary application power the MR1100 from a separate UPS. You'll need one anyway for your wireless access point(s) and other networking / security / camera gear. Or a large 20K to 26.5K mAh portable QC2/3 capable battery pack
Thank you
OH.
MY.
GOSH.
Two days ago, for no good reason I could articulate right now, I thought of doing something that I never thought would have the slightest interesting effect.
Today, I have a charged battery. In fact, I have one charging, and another (spare) charged.
Want to know what I did?
I turned off the @#$% screen.
That's all.
Apparently, that stupid little LED screen is what generates so much heat that the thermister hyperreacts and shuts down battery charging. Or perhaps the thermister is simply too close to the screen so as to make it too sensitive to whatever heat the screen generates. Don't know. Don't care.
See screenshot. Go to Advanced Settings -> Device and give it a timeout. It'll go dark shortly. Then it'll go cool. Then it'll go charge.
Let me say it again... Once more, with feeling:
OH.
MY.GOSH.
