Hi all, i have a P20 Lite which cannot be turned on. At first I thought the battery was causing problems, I found out that as soon as I plug in a charging cable, the power supply turns off and on again, which looks like a short circuit to me - anyone have an idea where I should start troubleshooting on the mainboard?

I powered off the phone last night and left on charge. Unplugged and tried to power on this morning and nothing happened.
Ive gotten to work now and plugged it back in and even with power connected it will not start.
Additionally the power light occasionally blinks off and back on twice in succession.
*UPDATE* insanely the problem i Had with both usb and mains intermittently not charging (or al least showing the red charging light) has gone but the phone still wont boot.
I have followed some of the soft reset advice holding in the power button for two seconds and the reset for 10 and apart from the power light flashing nothing else is happening

I am not sure Your battery was charging at the night. You wrote "and left on charge" but did You notice tg01 started to charge ?
Such effects with blinking leds are typically met on some tg01's when battery has been discharged too much. There is a problem to charge it inside tg01 then.
My advice is to charge battery a little bit in external charger ( to about 3.4V if You have opportunity to measure it ) and then continue and finish inside tg01.

damn i havent got an external charger
Yes the light did come on to show it was charging but it was still on this morning some 6 hours later which it hasnt been normally but you are right in your assumption that it had drained completely, it hadnt when i started trying to plug in the charger but by the 50th attempt it had shut itself down completely.
i was umming and ahing about getting one on ebay the other day and opted for the micro to mini usb adapter in the end which ironically has arrived today.
is there one in partucular you would recommend?

Unfortunately I do not know what models are available on the market. I even do not know whether such devices are available at all for tg01 battery.
I am electronical engeneer so for such purposes like Your ( one time usage ) I utilize anything I have at home . Colegues from the forum, having the same problem, utilized DC power supply with voltage and current limitations and it is cheapest solutions if You of course have such device. I do not know what are Your manual and electronic skills but as I mentioned You do not have to charge externally the battery too long ( to about 3.4V ) so other solution is possible but it requires any multimeter , any non regulated DC power supply and resistor to limit charging current. As DC source You can utlize USB socket . As You see You have some options.

here i find the link for you - http://forum.xda-developers.com/showpost.php?p=9587737&postcount=19 for external charge for ur tg01
Awesome - thanks - have seen similar mains powered items on ebay. will grab one of there for £4 delivered.
YAY
Universal charger arrived lunchtime, went home, brought it back to work and now have a 70% charged battery and working TG01
BOOH
Despite the fact that when the battery was dead every time the usb or mains charger was plugged in the red charging light came on, now the phone is ON the usb connection is again not working

using a mains charger works but its back to not connecting every time, i thought it was the usb port but now i really don't know. am starting to lose love for this device rapidly at the moment

Once again.
Mains charger works every time but You are not able to establish connection ( active sync or mass storage mode ) to PC ? ( not every time ).
If yes, maybe micro USB plug from cable You connect tg01 from PC is damaged or cable itself has any internal damage causing that one time connection is possible, other time is not possible.
Worse possible scenario is that micro USB socket in tg01 is damaged ( transmission lines or ID line ).

Just use a miniUSB cable and plug it into your computer. Any USB wall charger should work. I've used iPhone USB chragers with a miniUSB cable, Nikon camera chargers, as well as a Motorola one. You just need to plug it into any USB port either on a wall or on your computer. Leave the device off while it charges overnight.
Problem with charged
I use both ways but no result , phone indicates to charged but battery not charging.Charger is original and consists of two parts: the charger and mini usb cable .When i run it sometimes on the displays show this message : The charging current is not enough for device power consumption.Please shut down unused applications , or switch to AC adapter. And I do not use any applications. I tried to load phone in the off position , indicates that the charger is ON but the battery is not charging .Please help if someone has the same problem

Try it with a different miniUSB cable. If you don't have one handy, miniUSB cables go for pennies on Amazon or eBay. You can find them in retail stores for about 10 dollars or so as well. If the cable isn't the problem, then it is either a problem with the charge port on the device, or the battery. It's far cheaper to trouble shoot the cable, so let's just start with that.
Sound like the charger is insufficient power, even though it says 1A. Try charging from a computer USB port and see if it charges. HTC don't list TP2 as suitable for this charger.
I am also facing same problem. LED shows charging but phone does not charge. And when I insert charger "USB TO PC" page shows up, Like I have connected the phone to PC.
Please Help...
I just had an issue charging which turned out to be an easy fix.
The led would come on and the icon would show charging but it wasn't increasing the battery %. Then I would get a message about the power not being enough and to plug it into a charger. I tried several chargers and was getting the same thing happening. I blew a few puffs into the charging port which looked clean and it was still happening. I wiggled the cable/plug in the port and occassionally the charging light would go on and off. The charging led even started to go on and off with the phone just sitting still on my table. I feared that my charging port had gone bad so I ordered 2 spare batteries and battery charger from ebay for $10 (works well and battery life good).
While waiting for the ebay purchase to arrive I did some reading up and saw that pins could be bent etc. In my fustration I used a pair of tweezers to gently scrape the charging port pins/contacts (in a straight direction). Then I used an old toothbrush and firmly brushed out the usb port - a whole bunch of lint and stuff come out of the port even though it had previously looked clean.
I plugged in my charger and bingo! My charging issue was gone.

That was the biggest problem with MiniUSB was the width and height of those ports. It's a haven for stray dust and dirt. They need to be brushed out every so often, especially when you just drop it in you pocket.
hi buy and it schould work
buy a new charging cable

I was facing the same charging problem and was looking for a solution. And i found this forum and read it and did the same thing and my problem is fix.. I can charge my mobile now. Thanks a lot for the great help.

All of these dumb charges, ie bricks in the wall, use the unused USB pins to communicate how much power they can provide. There are some resistors they put on the D-/D+ to say this is a 700ma charger or whatever. Trouble is that there are limited standards on these resistors so it's more than possible that a phone will charge but not enter high current charging when attached to a new brick in the wall. The cables however are more universal.
Hey all,
I run a P760 with stock JB rooted. I also tried out PACMAN before on the phone, but came back to stock.
One day, when I plugged in the charger of my phone (wall), the phone went off and could not turn it on again until I took the cable out of the phone. The behavior is the same when plugging it in USB. The strange thing is that the phone, while off, charges and runs normally otherwise.
Also, if I plug in the cable without connecting it to the computer, the phone does not turn off.
Anybody knows why this happens?
Thanks!
I was having the same problem with this phone. After searching around on the Nexus forums, somebody mentioned the charging port was bent. Somebody also mentioned that the pins connecting the battery to the logic board were also at fault.
I recently purchased an aftermarket replacement battery, so I thought it might be the latter.
Here's how I fixed it: I took a tiny screwdriver and straightened the charging port connector slightly. I also pulled the battery out and pulled on the connectors near the physical battery a tiny bit with some tweezers (be careful not to rip them out!)
After doing both of these, I plugged my phone in and it stayed on.
Hope this helps.
Hello, my Huawei y300 (u8833) only turn on and works while I plug in my usb cable either (charge). My phone doesn't turn on when i press the power button and I'm on just my battery, amazingly it turns on instantly after i plug in the usb charger and remove the battery. So i got a little tired of having to plug in my phone all the time and not use it on battery. Any help? I dropped my phone 9 months ago and it didn't work back then but i never tried the usb cable on without battery. But now after 9 months i plugged in usb cable and no battery and *boom* it works. Any advice as to what is going on? Can i ever get it to work from my battery? (BTW there is a red notification light (not blinking) if i put battery in along with usb cable. Thanks for any help.
Update: Somehow its charging my battery!
Update: (PS:I'm rooted and have cwm)
Update: I'm fuc*ing stupid, its now working on battery! Sorry to have waster your time
Since last days, my POCO F1 don't start charging sometimes I connect the cable. Cases when it start charging or don't charge are randomly. I bought the phone in November 2018 and since now it was charged with the original charger and cable. I also tried to charge it with another original Xiaomi charger and cable from another Poco F1. The behaviour is the same. I don't use to let the phone charging overnight.I have performed a factory reset on the phone, I even installed the last Beta ROM, but the problem is still there.
The interesting part is when the phone is turned off and I connect the cable, it start charging every time. For example, if I connect the cable when the phone is ON and it happen to be the case to not start charging, if I turn the phone OFF, it start charging.
I also tried to gently clean the usb-c socket from dust, but the behaviour is the same.

Does anybody have an idea about what to do? Thank you very much.

The fact that when you turn the fone off it's starts charging leads her to believe that the ambient temperature where you are is quite high, 35°+. If this assumption is correct then you'll need to let things cool down before charging the fone.
same issue
i have same issue do you found any solution ?
Anybody found the solution? My phone charges at very slow rate (1%-2% per hour).
Had the same issue,just do a complete fastboot flash,it will get fixed...???
HELP!!
I am facing the exact problem you faced. If you found a solution or anyone finds one please tell me. I'm facing this problem for the past 5 days.
