Xperia U not turning on

[#1]

Hello

My sony xperia u wont turn on, i've not done anything that could harm the phone.. I used the phone yesterday, and it went empty of battery so i left it on a table..

Now, when i've charged it for like 2 hours, the phone wont turn on again, what's wrong?

Take out the battery. Keep it out for 10 mins. Put it in. Charge for an hour. Start.

Do you get any response from the phone at all when you try to power it on?

Different case.

MyXPERIA U shows 50 % in the battery.

Left the phone for a while. Check the phone and it hanged.

So I remove the battery and put it back but it won't turn on.

Plug in to USB it show the red indicator for charging.

Remove the battery for 10 mins.

Plug in AC and SONY logo comes up.

And shows it was drained.

Since today my phone died because of my battery. I have tried the 10 min method above but didnt work. When i try to turn on the power it vibrates very quick + left led bar flashed yellow. That's it nothing else happenes.

Anything else i can try? Because  this phone isnt even 4 months old

I have similar problem here.
I had problems with connecting to pc companion, i tried reinstall usb drivers, pc companion, reconnect, and restart many times.Then windows bliped again for no reason it poped up the usb connection sound again, and here i had enugh, and i disconnected the phone.
It had just a dead clen screen, and the bottom was glowing.
Then i waited, then i removed the batery, since that i can not turn it on.
Btw, the batery was quite low. And here we do not have AC charger, the phone is a gift to my mom.
So we need to solve it via USB charging, and we need to solve it fast, i am flying back to london in 8 hours.
Thank You!
