[Q] Phone doesn't turn on - it only vibrates when battery is in

Hi to all,
2 days ago my phone just suddenly didn't want to turn on (before that it was turned on, with full battery, working normally - but after 2, 3 hours in a car /there was not direct sun, humid, etc../ it did not want to turn on).
When i put battery in the small light on the bottom of the phone starts to shine (it also changes colours to green, blue, yellow...) and phone keeps vibrating. If I hold power button for approx. 10 seconds than it stops vibrating. But the screen is black and nothing else changes.
I also did not install any updates or anything.
What could possibly be wrong?
p.s. when I try to connect phone with USB to my PC it recognizes that the phone is connected to the PC, but I cannot access to my personal data or do anything in Xperia PC programme..

Pc companion - repair? If repairing it doesnt work, you should ask sony service.

[Q] One S wont charge or turn on

Woke up one morning and the phone was stuck on the startup screen. Turned it off, and when I rebooted, it still was stuck on the startup screen. Then, after a day or two, it would not reboot at all. no red light when plugged in charger. also when its plugged to pc, pc is making sounds like its plugged and then unplugged many times. is it possible to fix it? or its dead motherboard?

Are you able to access the bootloader?? By pressing volume down and the power on button simultaneously while no cable is connected to the phone?

Is it bricked or just battery

So the Xperia z3 will not start and it seems that it doesn`t charge, furhther it wont turn on.
Tried VOL+\- + Power button and the little button behind the SIM-Cover - no reaction
When I connect it with a (working) charging unit the LED will light up red and the display shows a battery-symbol filled red on the bottom (10%)for a few seconds, then it turns off and shows the same things (led and screeen). Well it is some kind of loop. I charged it for over 24 hours with different charging devices (up to >2A)
When I connect it to a PC the LED is dark blue. PC Companion says that the phone is locked and I schould unlock it, which is impossible as I am not able to turn the device on
Connecting it to the PC while holding the VOl- the PC Companion can do a software-repair and it says it works, but it doesn`t change the behavior of the phone.

I once got hands on an old Z3 wich showed the same behavior, it was just the battery. I changed the battery and it is now working fine again.

Hi
I have a u11.
last week while i was working with my phone suddenly it hanged and i tried to soft reset.
after that phone showed me blackscreen and nothing happened even i connect phone to the charger and charging led not showing and phone cant power on.
i tried a lot of methods with power and volume buttons but they didnt work.
when i connect phone to the pc it shows qusb_bulk driver or qualcomm hs-usb qdloader 9008
What happened and what can i do?
thanks

same problems
wait for helps

Hi,
I had the exact same problem:
HTC U11 just dropped dead in the middle of a phone call
- Would not turn on again.
- Would not soft-reset (pressing volumeLow + Power button for 10 secs makes the phone vibrate and the screen backlight turn on but the screen remains black).
- Would not charge (screen stays black).
- When connected to a Win10 PC via USB, it is detected as 'qusb_bulk' but no drive is shown
SOLUTION:
I removed the Sim card (not sure if this is even necessary).
Then I opened the phone (see tutorials on youtube etc) and disconnected the battery, then pressed the Power-button (just to make sure the remaining energy is drained). Then reconnect the battery and: it turns on just fine!

Nothing will happen with this solution, ur problem was different u could just reconnect the battery and ur issue would have been fixed

My honor 4C doesn't charge and the led flashed Red Green Green 3 times but no power

When I connect it to the charger it glows red green green and repeats for 2 times after. If I connect it to the PC and turn it on, the PC makes a connected device sound but still it doesn't turn on. Anyone here knows what it is? Is it bricked?

No clue and found little on a Google search.
If you can easily disconnect the battery, try that.
Better if you can command it to do a hard reboot.
A hard reboot can sometimes resolve issues.
May be a hardware failure.
