If you don't have the Xperia Companion software installed on the relevant computer,

Restarting, resetting and repairing
You can force your device to restart or shut down if it stops responding or won't
restart normally. No settings or personal data get deleted.
You can also reset your device to its original factory settings. This action is
sometimes necessary if your device stops functioning properly, but note that if you
want to keep any important data, you should first back up this data to a memory
card or other non-internal memory. For more information, see
synchronising with a Google account on page 36.
If your device fails to turn on or you want to reset your device's software, you can
use Xperia Companion to repair your device. For more information on using Xperia
Companion, see Xperia Companion web site
