Hi,

Did you do anything special when this happend? You can always try to hold down the ON/OFF + volume up(+) button for 5-10 seconds to force a shutdown of your device to see if this can help.

i tried this and nothing works

i dont know what you mean when you say anything special!!!  If you mean that i did bad use of the device i didnt 

7 months old device and doesnt work

No, I did not mean that you did something bad with your device. For example, if you installed any application, changed a setting or similar. But if there are no respond at all when you try to turn on Wi-Fi, I suggest that you perform a software repair via PC Companion:

http://support.sonymobile.com/global-en/tools/pc-companion/

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

Note that your personal data will be lost when doing this software repair, don't forget to make a backup.

Connect the tablet to a wall charger > press and hold power & volume up for 10 seconds > let the tablet charge for 3 hours > even if it doesn't seem to be charging, let it charge for 3 hours > then report back.

I apologize about the Wi-Fi part, I got confused by the title. But follow uliwoolys suggestion to see if that can help.

Finally My tablet wanted some rest!  when i put it on jack today it started to charge

immediately. I made a fully charge of the tablet and now it seems that works fine.

Thank you for your usefull advise
