Do you know what to do if the USB cable is fallen into the water?
What if I accidentally dropped the data cable into the water
If this happens, first blow the water with a hairdryer and put it in a dry place for a period of time. Do not charge it with water. It is prone to short circuits and burns out the data cable.
Secondly, it is necessary to see whether the copper on the plug interface is oxidized or not. If yes, you can scrape it with a sharp object to avoid affecting the power supply.
At last, please make a pow-on test, pay attention to whether the cable is overheated or not, if yes, we do recommend to replace the new USB cable.

The VCC and GND are very near each other on a standard USB 3 or 2 cable. If dropped into water with some sort of impurity (and usually it has) the external shell and contacts are prone to oxidation in the form of rust.
With how cheap cables are, the pragmatic solution would be to simply replace the cable.

Hi,
I have a kaiser with either a mainboard/usb fault. HTC wanted £250 to fix, so a repair is out of the question.
If I charge the battery on another Kaiser and stick it in my faulty one then my faulty one works fine for a few hours (it discharges more rapidly than it should - I assume due to the fault, but works for probably 4 hours) there is no way of charging via the faulty phone mini usb connector (it lights up amber but doesn't charge, nor does the USB connection hook onto the computer).
Luckily I had hardspl on the phone from new and can easily update via the uSD card if any need.
My questions are these: How can I hard wire my kaiser to a power supply so that I can leave it on in my car at all times? (it doesn't need to be moved)
The battery is 4.2v, can I hook a 5v supply onto the 2 outer pins?
What are the other 2 pins for?
Do I need to connect the 4 copper pads in the battery compartment together?
Thanks for any help that you guys can give!

check out the service manual
Hi,
Thanks for that, I scoured through the service manual but I couldn't find anything about the voltages on the battery compartment terminals and therefore how to hotwire power straight into them, I don't know much about this and didn't want to screw it up worse than it already is by sticking 5volts onto them. Looking at the markings on the battery power to the outer 2 terminals would do it but i'm sure there's more to it than that.
Dan.
Many angles to this.
Battery is 3.7 volts. You'd want to supply that. But there is a battery charging circuit inside the phone. How that will effect things? I don't know.
There is a circuit in the battery that gives you battery % I believe. Unless you feel like reverse engineering that, you're in a tight spot.
I'd say save your cash, and buy a new phone. this probably won't end well.
on second thought. If you're already willing to hardwire contacts, why not just hardwire 5V to the USB pins?
Keep your battery in there and you'll have 5V on the usb port keeping everything happy
Hmmmn, you might be on to something with that, the problem with the phone is that it doesn't charge when hooked up. The power light glows amber but it actually makes the phone DISCHARGE faster than when not connected. Once the battery gets completely drained all I get is a RED led.
When I sent it back to HTC they said water damage right away. I know for a fact that it hadn't been wet in more than 2 months (it did get wet but only a few raindrops, just enough I guess to wet a detector strip) from when this fault occurred so perhaps it's not a mainboard fault and is in fact the USB connector failure another thread is referring to....Hmmmm.
Gonna give it a bit of thought and then either get the soldering iron out or just bang it on ebay for spares. Should think the screen assembly would be worth a fair bit!
Perhaps I misunderstood.
If you're getting the magical amber LED while the USB is plugged in, I'll say you have a good connection. I wouldn't screw with any soldering. It does sound like you have a short somewhere.
I only had my phone drain faster than it could charge when I setup a bittorrent client on my phone. Got warm!
Inspecting the board for damage might be the best choice. I've seen a motherboard on a laptop that went out with visible water damage. I scraped off an area with "ick" on it that was shorting out two contacts.
If you can't solve it that way, I'd try to disable 3G/bluetooth/wifi and see how low you can get your power consumption.
Help guys. Do appreciate a little help here. I have a phone cover for Galaxy Note and it covers it perfectly except a little problem with the opening of cover at the microUSB area. The hole over the microUSB area is not properly cut. It means that whenever I would plug the microUSB wire into the port during charging, it wouldn't fit perfectly. However, the battery still indicates that it is charging eventhough the microUSB charging wire is only plugged into the microUSB port halfway.Battery always charged to a 100%. My question is could plugging the microUSB wire halfway into the port damage the phone in anyway while it's charging? Thanks.
Not likely, but there is a chance it might damage the phone. Since it's not properly inserted, some connectors might hit wrong pins, especially when moved.
Probably best to just take the case off for charging.
Hi, 3 days ago I decided to clean my micro usb port from my moto G, there was dust in impurities gathered inside and the cable woud pop out. after that the phone refused to charge anymore.. THe port looks fine. However, when I open the phone is fastboot mode, It does display that I plugged in the usb cable into the computer, but its still not charging. Anyone has a familiar experience or advice. I decided to come to you guys first before taking the phone to the bin, I mean to the serivice.
How did you clean the USB port? I mean what did you use? You have to be careful as you don't want to damage the connections inside. Best way usually is very gently with a toothpick first for larger particles. Then try using a dust buster to hoover up smaller dust particles and finally a cotton ear bud(dry) and don't ram it in there otherwise some of the cotton fibres can come loose and stay behind in USB port. I sometimes as an extra measure might take lid off bottle of my computer monitor cleaning spray and quick dip the earbud in the solution so its barely damp. The reason I recommend the PC monitor cleaning spray is that it is designed to be used on fragile surfaces and creates minimal or no static, which is one of the last things you need in a charging port, lots of static!
Ok folks, buckle up. This is a weird one. So, my phone is in perfect condition, I've never dropped it, it's never been in or near liquid. About four or five days ago, when I was about to plug it in, I received the "moisture detected" message. Well that was impossible, because I had it on my desk the entire time, and there has been no liquid anywhere near it. So I assumed it was a glitch, and plugged it in, only to wake up to a dead phone. I then discovered, that it WILL charge, but only if the USB-C cable is flipped a certain way, which makes no sense to me, given that they are supposed to be reversable. The OTHER insane thing I've discovered, is that it will work BOTH ways, when plugged into a tablet with a USB port. So it seems to only be doing this with wall chargers. Any ideas?
It's very obvious your phone's jack is defective, and probably shorting out causing "moisture detection" errors. Tablet even on USB3.0 mode do not have the same electric potential (aka Volts) as a wall charger. It's usually 5x5V versus 1x120V maximums for wall chargers usually. This makes sense in your situation. The jack is for lack of better words crapping out. Use your warranty rights. Other case scenario (minor chance): your USB-C cable is bad which would explain the reverse issues.
This really isn't that weird in my opinion speaking purely from a Physics level.
Well it has only shown that message once, and not again. I just thought it was odd that it WILL charge with the USB-C inserted one way, but not the other. That's what was throwing me off.
Yeah not that odd assuming the jack is damaged or the cable. As then that can change electric flux around the magnetic field of the connector randomly (not necessarily side-specific). Try another USB-C cable just to rule out the cable and file for a warranty

I have bad luck with type c plugs noticing the trap much more dirt and pocket junk in them than type bs You might a bright lite and a sewing needle or something and make sure there is no debris in the port and or cable....
I use magnetic cables just to avoid wear and lint or dust in usb port, besides, where I live the ambient is very humid
question.... are you using the original cable that came with the Note 8, if not, try that and see if you still have the problem.
The moisture detected notification could be caused by the cable or it could be a software problem, I had that issue and phone was sent in for warranty to get it fixed.
if you get the moisture error again you can still charge the phone by turning it off and then just as you switch it back on you plug in the charging cable

What adapter do you use? As in what brand magnetic tip sits in the device?
Hi,
a few days ago, my good old Nook HD+ stopped charging and my PC won't detect it as well. When connected to powerbank/PC, only green light shows on besides charging connector.
It's most likely caused by corrosion in connector. I've bought two replacement cables, both of them don't work.
I've dissasembled my Nook and measured resistance between USB wires and matching pins on connector on motherboard. Power pins seem to be fine, but one of data lines had about 0.5 higher resistance than the other. I've tried cleaning the connector carefully with IPA and toothpick, but that didn't help.
Question is, what are the options? Is it possible to buy replacement connector?
If not, has someone tried replacing connector with microusb, that is by cutting and rerouting traces on motherboard so that it matches micro USB connector? I don't really care about HDMI/audio functionality, all I need is charging and file transfer.
I've placed motherboard into cheap ultrasonic cleaner with IPA for a few minutes and that fixed the issue. Connector works as before.
Only side effect of repair is, that my nook stopped booting CM 10 from SD card. But that another unrelated issue.
