or try hard reset.

Looks more like you have a dead battery than anything. Check and make sure your battery works and has power, with perhaps another phone.

Unit powers off but wont come back on (Have to soft reset?)

Hey Guys,
Using 2.06 SE ROM, 1.18 Radio and whatever extended rom you like (even a blank extended rom), whenever I press the power button on my device, or if it turns itself off after the default 3 minutes, it wont turn back on!
It turns off, the green light keeps blinking every few seconds...but when I press the power button the screen stays black and the green light stops blinking. I have to soft reset the device to turn it back on.
Strangly enough if someone rings the phone it will wake itself up.
It doesnt exibit this problem when in the cradle.
Regards,
Jez.
Hi! i have this same problem:
http://forum.xda-developers.com/viewtopic.php?t=13789
i hope this weekend correct it.
Hmm...this is so weird.
Ive just taken everything out of the extended rom, and hard reset. The problem went away (i can power off/on fine, with or without cradle. I can now leave the device for 3 minutes so it powers itself off, then power it back on with no problems).
I then put all the cab files back in 1 at a time until my extended rom was identical to before (when I had the problem)...and guess what...still no problem. I dont get it...

Blinking Green light and cant turn phone off

When I start up the phone it blinkes green all the time, and when i press the power button nothing happens, I cant turn it off. Also the screen doesnt turn off itself so its basically on the whole time. How can I fix this?

Hi!
Try to reset by pushing the small button under the battery cover.
Other way:make hard reset.(First try to make full backup all of your data via Activesync connection).
Have you tried to connect via Activesync?

[Q] My Tablet Screen Is Blank.

Suddenly my tab is not responding , I tried to press ON/OFF button but the screen does not respond. The screen is blank and nothing comes out. I tried to plug the charger and no respond. I never or change anything since I brought the tab. I tried to google also but I cant find the solution. Is there any solution? My tab cannot turn on and the screen is blank and nothing to appear. It's like my tablet running out the battery but I plug the charger still no respond..

Can you try holding Power button for a about 10 seconds or more, release it and try turning it on again normally?

How to switch on Xiaomi Mi4i without the power button

Hi,
My phone has a faulty power button and I'm unable to get it fixed. I've found easy work-arounds for it for locking and unlocking the phone. However, I'm not sure how to turn on the phone if it's switched off.
When I connect the charger, even if the battery is 90% it won't turn on on its own...

Nope, the only way I could turn it on was to open the back cover (very painful process) and then press the button area with a pin.
Couldn't get it fixed, so I had to change the phone.
I think there are possibilities in rooted phones, but otherwise the best thing to do is to keep a battery alarm at 30% or more, and keep it on charging whenever you can to avoid a power off. In power on, there are many ways of locking the screen in the MI UI.

Thanks. I installed Blocco Schermo - Simi Studio v.3.21 , a simple app to lock the screen...and when i flagged the option "show in notification area" , the problem magically disappeared.. The Power On/Off button started to work again. I think it was an hardware problem (because the problem has come up after the phone was at the sunlight for hours in my car and went very hot) but now i think it's obviously a software problem.
Hi guys, I got the same problem too. Unfortunately, I drained my batt while playing games. So the problem now is I can't turn it on. Any idea how to turn on the phone without using the power button?
I solved it
Hi guys i solved a problem! You should hold main button + down volume button for 10-20 seconds. Then, when MI Remote opens, stay on the reboot and wait about 3 minutes, then stay on the reboot systems as well. Great work!
just change the volume flexible. its also not took much cost.
