So I've had my zenwatch for about a week now and lastnight it was working perfectly fine but this morning I woke up and my screen was black. I placed it on the charging cradle (which normally triggers the screen to turn on) this time nothing happens, the white charging indicator light on the cradle lights up but the screen does not cut on. I've tried holding down the power button, cleaning off the charging prongs, even using the usb of a pc for trickle charging but nothing seems to wake the screen up. Has anyone else ran into a similar problem? Know of a possible solution?
Thanks

If the battery is totally flat it can take a while to show signs of life. Leave it on charge for half an hour and see what happens.
Left it on the chargwr for 8 hrs last night. Still no sign of life. Its so weird i have only had the watch for 1 week and its in perfrct condition. It just wont cut on.
Did you get an answer to this as I'm now in same position
Same thing has now happened to me!
Maybe they have a self destruct ready for Zenwatch 2 release! Will have to get my Moto out of hibernation when I get back home....
I am not sure but I think your watch is dead. One of my friends was using the Zenwatch and he has faced the same kind of problem. He couldn't get back his watch. You can contact with customer service.
Bug bug bug
Same problem happen to me... after 2 month of usage (updated to 5.1.1)
Accidentally my watch wont charge anymore until the battery running out
If I put my watch on charging craddle with original travel charger, the white led indicator of craddle turn on but my watch still won't charging and the screen just black... no vibration, no display, no sign of life... try to press power button as long as I can.. doesn't help...
Is this hardware defects or just software problem?
Anyone has solution or fix for this?
It is so weird..
Same issue. didn't charge it for a week and now wont show any signs of life even after leaving it on the charger for days. also tried holding the reset button for minutes.
Hi,
just recently I had the case with ZenWatch from Asus, which was shelved for one year. After connecting to charger screen stayed black and watch was vibrating (short vibration every two seconds).
This is typical fault of COMPLETELY discharged battery. Had such cases with telephones before. By experiment I found the way long time ago. You have to "initiate" or "ignite" battery. In case of telephone batteries take out battery, use old USB cable, clean wires from insulation from one end (opposite to male plug). Use black (-) and red (+) wires as 5 V supply. Identify + an - on battery. Prepare your phone, watch charger for charging. Touch end of + wire to + contact on battery/watch and - to - accordingly for about 20 - 30 seconds. After that quickly put battery to phone or watch to charger and normal charging will start. Be careful not to make any short circuit with wires or wrong terminals.
I made it many times and always successful. In case of Asus Zenwatch proper contacts are these corresponding to first two pins of charging cradle from the side of USB connection - outer one is ground (-) next one is +.
Good luck!
Happened to me recently after washing my watch. Turned out there was a little bit of water inside and after drying it, it powered up and started to charge properly again
I've recently had the same problem. When I connect the charger, the watch vibrates once then does nothing. Screen stays black no matter what I do, and I've left it charging for days now

My Note 8 only receives power when plugged in. I have replaced the power port but problem persists. Battery shows 100% but when I remove the power cord it dies. Any help would be appreciated.
Could be bad battery or needs a power reset, open the backside cover and unplug the battery connector and wait 2 minutes, and reconnect.
I did this while installing the new power port. I have ordered a new battery. I'.lol report back with the results. Thanks for your input
fwiw I got this off eBay for $15 so I have some monetary leeway as far as repairs go.

Your tablet only runs when plugged in even when battery is full, possibly the battery connector has some open pins. Re solder the black battery connector may fix it.
Open pins can fool your tablet the battery capacity. For example, disconnect battery cable from battery connector, plugged in and press the HOME button, it will show the green battery icon is charging, then within 30 seconds, it will show the 100% battery icon. When sensor from the mainboard doesn't see any drawing charging current , it will send the signal to charging circuit the battery is full and it should disconnect. This behavior you can test on any Samsung tablet to see if charging port is drawing current to battery connector or it's working.
Any repair shop or anyone knows how to solder can help you, this re solder only takes under 5 minutes and you only need to disconnect battery cable.
Here what it looks like when I fool my tablet by disconnected the battery while charging:

This can be bad battery or open, cracked battery connector. When change new battery, don't put back the rear cover, test if your charging port is working without battery. Then connect the battery, press the HOME button to see the flashing green battery icon. If it's OK, waiting for at least one hour, press the power button to turn on. If it's turn on, you have a bad battery.
If it doesn't turn on with new battery, then the battery connector is the source of problem and need to be re soldered.
This is the battery connector you should look for, I already re soldered this black connector by adding more solders to 6 joints:
Beut, installed new battery today with no change. I did as you suggested and the device did register 100% battery even though one was not present. The area around the battery connector appears to either have corrosion (slight) or maybe a power surge. Just doesn't look right.
I only paid $15 for this and the fact that it runs fine while plugged in I'll probably take it to work and use it to watch the EPL games on Saturdays. Maybe at some point I'll come across a working unit with a bad screen.
Thanks again for your help. Keith

I think you should re solder this battery connector, it takes only few minutes for who knows how to solder.
Any repair shop can assist you with little charge as it's only a 5 minutes work.
Cracked battery connector is very common in Samsung tablets, not just this tablet.
Maybe I'll give that a shot at some point. I guess I can't make it any worse. The connector looks a little odd near the two red wires coming from the battery.
Hello,
I have several Tab Pro's that are all having the same problem. I have charged the devices to 100% then when it sits for a few days it will not turn back on. I have plugged it back in and it show 0%.
This is what i have done to try and find the issue...
1. I have reset all cables
2.Tried different batteries (USED)
3.Re-Rom with ODIN and Factory reset
4.Checked the pins on battery terminal for bad solder contacts
5.Waiting on new batteries
Now the interesting part. I charged 2 devices to 100% then disconnected the battery from the Logic board so I could check to see if the battery is discharging on its own. After 3 days I reconnected the battery terminal and tried to turn it back on. They will not power on, then I plug in the charger and battery icon shows up with 100% and then I'm able to turn it back on. Any ideas what the issues with these are I have about 8 of them all doing the same thing?
Thank you,
The battery doesn't discharge on its own so fast like your description. I have a Tab Pro 12.2 , which is off almost 3 months, when turns on it still keep the charge at 99%

The problem is from the cracked battery connector, it will cause intermittent connection. Trust me, remove the back cover, use your hand to press directly on the battery connector while turning it on, it might work depending how bad the crack is. All you need is resolder the battery connector.

I have tried to resolder a few of them and they still do not turn on or they discharge the battery. I have a few that I charged the batteries up to 100% and disconnected them from the battery terminal on the logic board over the weekend. They all still do not turn on, then I connect the charger and the battery icon shows up with 100% then I can turn it on. I have tried what you said and pushed on the terminals on all of the ones I have and not one will turn on. I'm starting to think there is a issue with the power management chip on the board. Has anyone tried to replace any of these?
I have had issues with SM-t/p900 12.2 pros that had the issues you are talking about, not charging, flickering screen, and the terminals needed to be resoldered. I could actually push the pins up and down. The SM-t520 pins are solid and do not move.
My battery gauge got stuck at 100% Tab will die without ever going down at all. Anyone have any ideas? I have rebooted several times, wiped the cache, and did a factory reset.
It is not rooted 8.4 inch Verizon LTE.

The battery shows 100% but immediate shuts down indicates your battery connector's joints have cracked, not connected to mainboard.
The same thing if your battery disconnected from mainboard, plug in your charger, press HOME button, it will briefly show the green 100% batttery icon

Bring it to a repair shop or anyone who knows how to solder, to resolder the battery connector.
It takes no more than 5 minutes

You can try to power on while pressing directly on the black battery connector to help closing the cracks.
Another case: the white battery connector with 6 wires has loose connection, try to disconnect and reconnect the battery may help.

Thanks but the battery works, just the gauge stays at 100% until it dies. If I charge it unplugged the gauge will start at 100% then slowly goes down then goes back up. But when I turn it on it stays at 100% the whole time.

The battery capacity goes up and down is an obvious sign of cracked battery connector. It will cause intermittent connection.
You need to read this threat to understand which is causing the problem, not only this model but other Samsung tablets as well.

Hey all,
I'm helping a friend out here. They had the phone on a nightstand in a hotel room and it fell a few feet (onto carpet). No physical damage, but after that happened the phone won't boot.
If it isn't connected to a charger, nothing happens. No response what so ever. When you plug in a charger the orange light comes on and the phone displays a battery symbol with a lightning bolt. However, after a few seconds the phone appears to reboot (screen goes black) and then return back to the same screen.
Things I've tried:
- Holding Power+Vol Down for 2 minutes.
- Holding the phone's light sensor to a bright light, then holding down Power+Vol Down.
- Different USB cable and wall ac adapter.
- Holding down Power, Vol Down, and Vol Up.
I disassembled it a bit to take a peak at all the connectors from the usb port and battery. After reseating them, I get the same result. I also tried leaving the battery disconnected, and powering it on via just the charger. Interestingly enough I get a battery symbol with a "0%", but it still doesn't boot.
Any suggestions? They just returned from a trip over seas and would like to get their pictures off the phone. They've already purchased a used M9 to replace it, but I'm just trying to get their data.
Picture of the screen I'm receiving:

Thanks!
P.S. Ignore the missing speaker grills on top and bottom. Those had to be removed (gently, of course) to remove the screws underneath which allowed me to take apart the phone.

It looks like the phone had been through much more than just a drop

Including the very weird substance on the speaker. Had this phone been in the water?

I love the A6 unit that I have but last week it lost the fast boot feature. At key off it shuts down and loses some settings and the time. I pulled the dash and the yellow wire has power when the key is off. I had installed the new firmware several weeks ago so it's been updated. Any suggestions? I emailed them but have not heard back.
I'm having basically the same issue. When the car has been turned off 80% of the time the head unit does a complete boot up. Sometimes it does it if the car is turned off and immediately turned back on. I also have lost settings suck as time. Everything else works perfectly and I haven't had any other issues as of yet. Had it for about a week now.

Just make sure the yellow wire has constant power even when the key is off. They made me jump through a bunch a hoops to get any action. I had to submit several videos and then they sent me a power adapter that plugged into a wall outlet to bypass the truck wiring and I had to video that also. They finally agreed to replace the radio with me sending the old one back first. I ended up keeping it and they gave me 20% off a Pro unit with the gestures. The day after I bought it they dropped the price on it 20.00. If I had it to do over again I'd just trade it for another and save the money. I doubt I'll be able to sell this old one with the problem it has. Let me know how it goes with them. It was probably a month of emails back and forth before I had a remedy.

I'm pretty sure I connected the yellow wire to the constant power correctly because it will work fine and boot instantly when I turn the car on but sometimes it won't. It's a bit frustrating but if that's the only issue I really have then so be it. Over all it's a decent head unit in my opinion. I guess that's just aftermarket BS when you install yourself.
Hello yall, well I bought atoto A6 and each time it was booting long, like the first time. So it the problem with the wires that goes with the mmc.

so the yellow and red wires are messed up. Or at least look for the right position of all wires. On the picture they are messed up so if U have wire same way than u need to switch em betwin and it will bot up crazy fast
Can you explain a little bit more about the process?
I have the same problem when I switch off the car, do I have to invert the yellow and red cable in the connector?
My iso harness had red and yellow swapped wrong. I had to use big paper clip to swap cables on the iso plug. Now it works like it should. Yellow is battery and also fatter cable. Red one is thinner. Google: iso harness pinout for reference.
