yep tryed it .. theres a red light on the power button whats that about?

Have you tried removing the charger and battery, then plug the charger back in, wait a few seconds, then put the battery back in (with the charger still connected). This usually solves the ol' red light/no power issue on my hermes. I only normally have to do this though if I accidently let the battery run completely flat.
Other than that, a red flashing LED when the power button is pressed on a sony ericsson device usually indicates an error. The LED flashes error codes based on either hardware or flash problems/errors... though I don't know if this will apply in this case on the basis its completely different hardware/software to "standard" SE devices.

hmm now the red is on constant on the power button i tryed the few things you guys mentioned but no luck maybe it need s a good charge again.. DOHHHH!!
i flicked throught he manual there is no detail about what the red light on the power button means

Hmmm - on my Wizard when the battery went flat I couldn't use a USB cable from the computer I had to charge it from the Wall socket. Your Xperia should have come with a normal plug to plug into a wall socket (you attach your USB cable to that).

why not call the X1 support?

after overnight charging there was no change, so i manged to boot it in flash mode let it on charge for a few min then i reset the phone and bingo it rebooted.. woooohoo

I followed your instructions.
But I cannot boot in flash mode (4colour) even though I charged it for a while, then press and hold Volume Down + Power together.
The illumination lights just flash and turn off.

Is it always like that? If you leave your phone with totally no power in the battery you can not start it later, or you have problems starting it?
I ask because I saw a couple of topics for that issue in the forum. Does everyone have this problem or it's for some devices only?

Do you use the origin SE-charger? I had the problem once and used the charger of the diamond from my wife since I was too lazy going up into the arttic searching for the carton. But the charger of the Diamond has too few ampere, so the battery of the Xperia didn't received enough power. Even using the USB-port of the computer didn't worked well.
So try using the origin charger and also don't let the battery get too low.

aah, I use the original charger of SE X1.
The Cause of problem:
+ I set the alarm. After it had notified, it still snoozed and ran out of battery.
+ I didn't know the current phone without power when I woke up. I turned it on and it had to used little power left inside (the saved power - I guess). From that point, X1 cannot be charged even you plug it all day and all night - different with other phones.
(My Cingular 8125 can be charged after 24hours charging continously).
* Any X1 and other PDA using window CE can suffer that problem.
The Solution:
* For other phones: just plug wallcharge in, after 24hours, it can be charged.
* For X1: You have to come to BOOT MODE (4colours)
(but if doing like above posts, you cannot come to boot mode with no power inside battery)
1. Remove the battery.
2. Plug to wallcharge.
3. Hold the volume Down + Power buttons.
4. Still keeping hold those 2 buttons in one hand, another put the batter back inside.
5. Wait until it turns into Boot Mode, released them and charge in 15 minutes (to make sure that it would receive a little power)
6. Remove the battery and plug back. Restart in Normal Mode and charge it.
* It is my experience after many trials in 9 crazy hours

Thank you for that useful post. It's good to know that there is a way out of that situation.

yeah omg,
thx for this this should be a sticky
i was listening to my music and got an notification that my battery is low, not even 2 minutes later my phone went off
and couldn't put it back on. the weird part is that the 10 prcnt of power drains that fast my music isn't loud (via media xperia panel - phone volume was 100% but music player was full for 2-3 blocks)
but anyway, thx

pek, you're a star. flawless fix.

When my wife's X1i run out of power completely two weeks ago I also first tried to use the original SE charger. No effect after 6 hours charge.
Next I tried my lab power supply which can provide 5V/3A current. It took less than an hour to charge the phone making it fully workable.
My car's charger can fully charge X1 from 20% battery to 100% in less than 45 minutes. 2A maximum current restricted. Fast charge seems have no influence on battery's life.
Also if you have a wall charger for X1 battery you can charge it outside the phone for some time (20 minutes usually enough). Also works.

Thanks for sharing this. Should stick it.

Think my X1a is bricked... anyone had this before?

I was just listening to music from TF3D and all of a sudden the screen turned off, music stopped, and the power button at the top was glowing red for a few seconds. I tried turning it back on, removing and reinserting the battery, but nothing happens. I can't turn it back on at all!
One thing I do notice is if I remove the battery, and plug in the usb cable connected to my computer, the power button glows red, but I can't turn it on. If I insert the battery, and then plug in the USB, the button doesn't glow red.
How would I recover the phone?

Try charging your phone for about an hour. The red light under the power button happened to me when i had used up all of my juice.

yeah i had the same problem and i had been very frightened of it...
just charge it...

Ah ok. Weird! Because when I was listening to music I had just taken it off the charger and it said 90% battery! And I had only listened to one song. I guess the battery meter was telling me false info =(
Thanks all

well maybe your battery was still kinda "new" so it wasnt showing correct data

a red light?
cool ... is this a phone or a light-generator?
it was the first pda with making so much noises by optical... but is good ...

Can anyone explain me how is the red light under the power button? The light doesn't come out from the illumination light, does it? I wanna see how is the light. Screenshot will be better.

It doesnt come out form the illumination light. It's by the power button. Usually it blinks when your battery is at 5% or close to total drained.

It´s a light that´s gives you battery error. I spent 2 days trying to figure it out because my phone wasn´t turning on and the red light was continuissly showin off, at the end it was because of a cheap wall charger (5V and 500ma, when SE uses 5v with 700ma) I just charged with SE wall charger and everything went back to normal.
In your case maybe one of you battery cells broke and that´s why it´s was at 90% giving you that hateful red light.
Here is a post conserning your problem:
http://forum.xda-developers.com/showthread.php?t=452402&highlight=red+light,+button

i think the battery is low quality fake..

i found out that the fasted way to charge your empty battery is:
1. remove your battery
2. insert you mini usb charger (NOT usb>mini-usb from your computer)
3. watch if the red light is on. (underneath your power button)
4. insert your battery.
5. after 5/10 minutes your X1 is working again.
you can do it by just plugging your charger on when it's empty but then it can take up to 2 days (YES, i have experienced it) to make your X1 working again.

another way is, just plug the wall charger to your x1 then leave it there. the x1 do not wake up that quick because the charge voltage goes up grandually/slowly for protect your battery and phone after the battery voltage same as charge voltage, then it can be charge normally*

Thank god that I read this topic yesterday. Otherwise I would have pissed my trousers because I had the same light today.

Battery is not charging

Hello, I have a problem with my HTC Kaiser. It is almost 2 years old and also a little bit battered, so I don't think, I have chance to get a warranty repair.
So, my Kaiser stopped recharging it's battery. When I plug AC adapter or USB cable, it is not charging, although USB is working (ActiveSync is synchronizing, internet sharing is working ...).
There are three scenarios: If the phone is ON and I plug in the cable, the display backlight switch into on-external-power mode, but the orange "charging diode" is not lighting.
If I turn off the phone and connect cable, charging diode starts lighting for about 20 seconds and then switch into blinking mode.
But when I quickly press power button, the diode stops blinking and starts permanently lighting, when I wait for a hour and then turn on the phone, the battery is still not charged (not even by a 1%..).
Do you have any ideas, where is the catch? I don't have second battery, so I am not able to test, whether the problem is in battery, or in the cellphone.
Uh, sorry, I forgot some details:
R 1.71.09.01
G 25.75.40.02
D 3.5.ROMeOS

Ehm. Yep. I bought new battery and now it is OK.

Dead phone - need help

hey guys,
I left my phone to download a few Mb of data for a game using Wifi. The phone was connected with PC thourgh USB cabel. When i came back red light was on and now it´s dead. I can´t turn it on anymore, everything it does is blink red light 3 times when i press the Turn on button.
Bootloader is unlocked.
Can i do something or is it really dead?

It seems i overheated the battery ... i cleaned arround the battery connector and now it works again - charging from 0%

Hi,
Could you add the [SOLVED] tag to the title?
Thanks,
~Lord

XT890 doesn't start at all.

Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?

Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,

Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?

Try opening and disconnect battery for a bit.

I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?

Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?

Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.

I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:

Did You enter medfield mode using combination with camera button??

By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.

Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.

Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?

Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.

Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.
