Hi to all masters,
I've just bought an O2 Xda Exec from ebay. I'm so happy that day when the device was delivered to me as this is my frist VGA screen pda. As i opened the box, i found out that the USB cable was missing, so i emailed the seller and he promised to send me the USB cable soon. Having no USB cable, I borrowed an USB 2.0 cable from my friend.
When unboxed, the battery was inserted into the device so i thought it can be turned on but i realised that the device doesnt turn on at all. Thinking that this might be caused by the drained battery, i pluged in the charger and the RIGHT LED illumates in RED instead (Amber indicates charging). I waited for 5 hours and tried to turn it on again but the problem is still there.
I'm thinking that the charger might be a problem so this time I used the USB cable and plug into the device. Surprisingly, the RIGHT LED now turn Amber and was able to turn on but showing critical battery level at 2%.
However, after a few minutes, the Amber light went off and the device stop charging. Then I turn off the power button and the Amber lights appear again. I realised that I can only charge the device by using the USB cable and that the device will be charged when it is turned off. Here is the summary of my device problem:
1) The device will not charge instead the battery will be drained when using the charger.
2) When using USB cable the device will ONLY charge when it is turned off.
3) When turn on the device and connect to the PC, the PC does not detect the deivce and the charging went off.
Ok, somehow i can find a way to charge it but the big problem now is i cant even get it sync to my PC.
When i turn on the device and connect it to my PC, there was no respond. I could only get the PC the detect the device in a split of a second when my device reboot at the beginning but it was detected as unknown device then it will dissapear.
My pc couldnt detect my O2! I've tried a few ways stated in this forum which are:
1) Hard reset device
2) Reinstall Active Sync
3) Using the software FixASRunAt.exe
4) Changing USB to IR and click Start and Stop
All these methods could not solve my device issue. Now I'm not sure if its the software problem or the hardware problem.
This is a weird problem for a pocket pc and I felt like I'm being cheated that i bought a faulty O2 Xda Exec. If there is someone who experienced this problem and know how to solve this problem please please please please help me. I really like this O2 Xda Exec and i wish it can be function as normal. Thanks.
This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.
you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?
What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.
Next time dont power off ur X1,
if same happends then your battery is suffed.

1) This was accidently
2) Why? I dont like it when mobile phones are on standby while I'm asleep. Charging the device when powerd off should make absolute no difference? Worked everytime but the one where it was connected to a powered of laptop.
Why will the Xperia been drained?

Do you mean standby or powered off? Why should it make any difference? And why does the battery getting drained?

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc
I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it
I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.
Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.
I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.
Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .
I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.
But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )
Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...
Help
seemed to have killed the battery on my HP614c ->
battery was at lowest point ( ie last bar) but had check my email for something urgent so i hooked the HP614c up to my laptop and used internet sharing,
the power from the usb was keeping the fone alive - phone tried to switch off about 5 times but usb power was keeping it from doing so, eventually the phone auto powered off but by that time the battery was left with no charge in it what so ever !!
If i start in sd loader the charging light comes on (ie it seems to be charging the battery then), but when phone is off or if phone is switched on in normal mode, the battery does not charge at all - i think I have killed the battery totally. If i switch the phone on the charging light would come on but there is not enough power in the battery to be on for more than one second .
Is there any other mode like bootloader that will enable me to only charge the battery up ?
or does it look like I have to buy another one
have you tried leaving it charging all night with the AC adapter?
I had same problem with a blueangel...
Solution? Buy a new one battery.
ok , strange one ...
got another hp 614c handset, but both batteries charge on the new fone
(so it wasnt the battery)
basically on the old phone what happened is that when the battery was at its lowest , i connected it to internet sharing via usb port
( it kept trying to turn off but stayed on - which i though was due to usb power keeping it alive ) - that was the last time the phone was able to ''charge''... it was charging perfectly before that.
so i 2nd presumed i had damaged the usb part of the old phone
however when i connect it to usb the phone connects via active sync perfectly and as a storage device ! it is fully operational apart from charging of the battery ?
surely if the usb port was damaged it would not connect via active sync etc ?
I am confused ..
anyone shed any light on this?
FOUND THE PROBLEM
MY 64 GB USB STICK (WHICH WAS PLUGGED INTO THE SAME PORT ) IS DEAD ALSO !!
LOOKS LIKE A PROBLEM WITH THE DESKTOP COMPUTER - MAYBE A POWER SURGE
..... ARRRRRGGGGHHH ( APOLOGIES FOR ANY WASTED TIME )
STILL SEEMS STRANGE THAT THE USB TO PC PART OF IT WORKS FINE STILL BUT NO CHARGING? WHY IS THIS?
Solution (for me anyway) for battery problems
Hi!
I had this problem some time ago.
If you use 220v charger connected to the phone, the red light will probably be on.
Try to take out the battery. Connect the phone to your charger (without battery in it) and wait for the light to go green. Then put back your battery and wait.
If this doesn't work, you can use an external charger.
I had this problem 3 times. This fixed it every time for me.

Hi all,
my 614c can be only charged when turned off.
(currently 61x_21888 beta 31 rom, but happenned on previous ROMs too)
When turned on (device booted, display active or standby), after connecting either usb cable from computer, or AC usb charger, device won't charge, LED is off.
To charge it, I must shutdown the device (usually i just remove and re-insert the battery) and connect the charger while powered off. The led turns orange, device starts charging and after few hours (i have extended battery), the led turns green and device is fully charged. Then I can boot it up and start using it until the battery drains again.
This means quite a problem for me, as I use my 614 for network access and being not able to charge while using it reduces worktime.
Has anyone observed same symptoms? Any solutions?
From my point of view, this must be some software problem, otherwise I wouldn't be able to charge it at all.
Thx in advance
Stan
