Charching problems - Lenovo Yoga Book Questions & Answers

Hi, can anyone explain why my yoga book sometimes does not load when it's in operation? Is the charger connected and I start it then it charges and when I unplug the charger and reconnect then it no longer charges. Exactly when I plug in during the operation, it does not load! When it's out, it always loads!

Have you tried using a different cable? Or a different charger? Or a combination of both?
Mine does come with a substandard cable (from the box) and I have since changed it to an aftermarket one! The difference in input/charging times is substantial..

Now my phone won't charge

Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?
Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.
Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.
Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)
Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...
im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).
Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.
I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.

[Q] Charging issue!

I'm on a road trip now and every time I connect the phone to a charger it switches it self off.
I have tried different cables and chargers. This also happens if I connect it to my Mac.
Is anyone else seeing this?
Thank you
Funny you should post this, today is the first day at work with my DVP and I tried to use a USB cable connected to my pc that charges my HD2 and SE MW600 headset, connected it to the Dell and it turned off just like you say. Probably not enough voltage/amps, I borrowed a BlackBerry charger and that works fine.

I noted this in my "Nit-picky" stuff post. Needs a 1Amp charger.
Same here.
The only charger that worked is the one that came with the DVP.
I tried the 1A iP4 charger, 750 mA of the Kindle, a third party dual 1A (each) charger, 1A car charger, 2.5A iPad charger and finally my computer.
None of these works, but if it has like 50% charge then it charges with any of the above...

It wouldn't even charge from your computer below 50%??

No...thats not true....But I have seen several different combinations work.
I have the Nexus 1, one of the Jawbone headsets, the HD2, HD7, DVP, and have access to the Focus and LG devices. All of these use the same type of cable.
The HDx cables, the Focus cable, and the Jawbones cables all work with sync and Charging. The LG cable does not...only works for the LG. Some of the older BB cables will only provide a sync or a charge...but not both.
The different USB charging adapters have different results also.
The DELL and HD7 adapter will work. They will work plugged into a wall or a power strip. The jawbone and HD2 usb adapter will not work plugged into a power strip at home, but, both of them will work plugged directly into a wall.
All the cables I have will work when plugged into a laptop, EXCEPT the LG. Apparently the LG cable I have access to only works with an LG.
Now to be honest, the HD7 shows no such reluctance to charge with any combination. The DVP does. My DVP does NOT require DELL only parts, but it is picky about what it will play with.
-My overnight charger is connected directly to the wall. It is a jawbone wired charger, no adapters or usb. All phones connect and charge ok with this.
-My Work office charger is a HD2 usb adapter with the HD2 charger cable.( which is strange because this one will not work at home plugged into a power strip.)
-My HOme office currently uses the Dell adapter plugged into a power strip with a generic sync cable. I say generic because I don't recall where it comes from...all I know its not the DVP or the HD7, because both of those cables are still wrapped up in the box they came with.
-My car charger is an ATT dual USB charger. It has last years model adapter, plus a USB connection. All my phones and head sets charge off of this combination quite nicely. I also have a Tmobile care charger but have not tested it yet.
There is definitely something different about the DVP and charging. I'm hoping Nicolas Cage will play the lead when this conspiracy is made into a movie.
the DVP will only charge with a 1A+ charger. the ones that come with BT headsets don't feed it enough to charge. USB cable plugged into a laptop USB port is hit or miss. The USB port in my car is 1.5A, charges the DVP really quick. I haven't found the make of the cable an issue, the DVP charges with any I've come across so far, HTC, BB, the cheap extendable cable from an airport, etc. it is picky about amps.
The cable is not the problem. I didn't mean that when I plug different cables it does not charge.
I have a charger hub which I connected many phones to it, HD2, palm pre, nexus one and few more and all of them charge from it. When I connect the DVP it shows its charging but in the morning the phone is dead, no charge at all.
BTW, it does charge from my laptop and desktop.
I charge my phone overnight on my PC and never had this issue

It will charge from the mac from 0... then when its about half charged it charges from any plug and cable combination
Sent from my HTC Vision using XDA App
I can't get mine to charge now at ALL..
Apparently it drained and shut off in my pocket. Went to charge like I normally do.. and NOTHING..
I noticed a weird behavior yesterday when charging it would jump from charging to not charging to charging. While sitting on my table. NO MOVEMENT to the cord or anything.
Tried Dell charger, tried aftermarket one (that I have been using for 2 months), and PC USB no response from the phone at all. Even tried to swap to a battery I know was low but not dead. Still no response from the phone.
The connection looks good.. but I am thinking maybe I am having a problem with the connector in the phone ?
Took my sons battery out (He also has a DVP) and booted my phone. Plugged it in and it started to charge. Then hot swapped batteries while it was plugged in.. let the battery charge up to 25% and now it charges fine again..
FUNNY it won't boot or charge while plugged in with a dead battery.. but will stay on if booted up and you remove the battery in it..

[Q] AC charging grinds phone to halt and prevents charging

I'm running:
GEN2
Rooted
ClockworkMod
Swedish Spring Android 2.2 with Gingerbread theme and circle battery
Suddenly after a few weeks of everything working fine, AC charging stopped working. USB charging still works perfectly, and when I plug the phone in it says it is AC charging, but the charge level barely changes - it can be plugged in for 12 hours and not gain or lose any charge. Also, sometimes but not always, the phone becomes very very slow, and sometimes the screen won't unlock - I have to unplug it, unlock, then plug it in again.
I've tried different chargers and cables and combinations thereof, I've tried turning USB charging off or on in Extra Settings, I've tried debug mode on USB or not, hardware acceleration on or off, I've tried charging with the phone off or on, screen on or off, I've tried charging it for 48 hours, the charge level never moves.
This is the closest thread I can find on the issue but it is a mix of problems, and they never find a reliable diagnosis or solution:
http://android.modaco.com/topic/336...rs-stopped-working-but-usb-charging-works-ok/
I don't care if it charges slowly, I'm thinking of trying to mod a USB cable to force it into USB charging mode. Anyone know how?
I far prefer this to re-installing because whenever I connect my phone to my laptop it immediately bluescreens, (despite a fresh Win7 reinstall), and I am lost on my gf's Mac.
These posts describe how to do the opposite (force AC mode) on HTCs:

Thanks enormously for any tips

Since I lost my charger and had to use a generic micro-USB charger, I have the same problem. USB charge works fine.
May be a problem with the USB cable, have you tried using another one?
(I'm on Ginger Stir Fry, but I don't think it is ROM dependent. )
Thanks for the thoughts. I've tried different cables and chargers and combinations thereof to no avail, hence suspecting something software and looking to mod a cable to force USB mode.
Please anyone know what PINs indicate laptop USB rather than AC USB?
How does my phone know to go into the (disfunctional) AC mode?
Thanks
I think D+ and D- pins (2 and 3) are connected. You would have to mod the charger. Or just use generic USB charger, like those from dealextreme...

Charging problems - only charging over USB

Hi there,
I have a big problem with charging my Galaxy S4. It only charges with my notebook USB Port, my AC-adapter does not work.
In the battery menu I can see that AC is connected, when I plug my adapter in. But charging does not work with my device.
Over USB I can charge slowly. This isn't a software problem, I have done some resets and firmware changes since the problem.
Maybe my phone got a little bit wet earlier. Could this be the problem? Can I fix this with changing the USB port part of the hardware?

Yes, I tried another cable but had no success
I dunno if I can ask it here, but i don't charge over usb, i mean it just "hold" the power level for me. Is that normal ?
Is your AC outlet working ?
Having issue where S4 only charges with USB and vibrates when using AC charger
I've been having some issues with my S4. I did recently get it a little wet, but it's working fine in all cases except charging. I have my phone next to my bed charging every night. I noticed it was dead one morning, but I figured I didn't connect the charger properly. The next night I noticed it was vibrating every 5 seconds or so, but the phone had turned off due to a low battery. Very strange behavior.
I realized that it would start charging, but it would stop between 1-3 minutes. The the phone would vibrate and not charge.
I've ready MANY posts from others with the same issue and someone mentioned their phone charges over USB. Seemed odd, but I tried it and voila, my phone charged perfectly. I have many samsung cables, none of which work. It's definitely not the cable. I can plug a samsung cable into my phone connected to AC and it doesn't work. I pull the USB portion out of the AC charger and plug into a computer and it immediately and consistently charges. The battery holds its charge as expected, so it doesn't appear to be a battery issue.
I've tried the developer mode options - no luck.
I've tried bending the charging prong - no luck.
I've tried blowing out the charging port with compressed air - no luck.
I recently got an update pushed to my phone (Sprint), but I don't think it was happening right after the update. Seems like a likely software issue.
I did get my phone a little wet recently, actually it was my young children throwing water at me.
I've read so many posts and nobody seems to have a good answer for this issue. Any suggestions are appreciated.

Please Help me - my cube-i7-book wont charge (Wall charger & Usb-c charger )

Hey guys
First, I hope I'm asking at the right forum. I searched at xda and it seems to be closest that fits. If there is a need to transfer it to different forum please do or let me know there to.
Than, I have a big problem and I do hope you can help me with- my Cube-i7-Book don't charge not by the Wall charger nor by the Usb-c charger.
I read a lot about the coube-I7-book and just before they started talking about the new one I bought it (+original keyboard). It arrived and I start using it about 3 moons ago.
1. Last moons I bought a Aukey fast USB desk charger (charge other devises ) and try to charge my cube-I7-book with the USB-c cable I got with my LG smartphone. It looks like the charger is connected but it doesn't charge (I try again and again).
2. Last night my cube-I7-book buttery was very low. I connected it to the wall charger as I always do and went to sleep. In the morning I took a look at the cubeI7-book. I was surprise to see it was still charging. I let it to continue charging. At the evening I checked again. It got 61% and stop charging. I re connect it to the charger and to a different wall socket - there was no reaction. I restart the cubeI7 book -nothing.
3. Could the problem is in the wall charger? If so what different charger l have to look for in order to check?
4. If it's not the charger, what can it be and what can I do to make it work? It is a new device and I really want it to work.
5. What about the USB-c charging? Why isn't it working? Can I do something about it?
Thank you for your help,
Did you manage to fix your problem. I have the same issue. Did you try to use a macbook usb-c charger, instead of a phone usb-c charger?
Only just seeing this, sounds odd. USB charging works well for me (although sometimes I need to unplug and replug the cable if charging doesn't start right away). You need to make sure that your USB c charger provides "power delivery " and in particular, I think, 12v charging, maybe 9v is also OK, but the standard 5v that some USB chargers provide is definitely not enough.
You may have a look at the forum on techtablets.com, there's a subforum for the i7 book with wire a few people active.
