My Z10 will not boot; need to retrieve contacts. Any suggestions?

I have had it checked no water damage, drop damage just stopped working yesterday tried soft reset not successful
Thanks ned

You said no liquid damage and physical damaged(never been dropped) that's a good thing.
Can you still see the red LED blinking?
If you can no longer see it even if you charge or insert the battery then there is a possibility that the problem of the unit is the board itself and not just software.
But even if you can recover your phone using software reload there is still no way you can retrieve your contacts, you can only retrieve your contacts once you turn on your phone,

Remove battery. Plug phone into computer, then insert battery and see what happens. Also, you can try removing the battery, leaving out for a half hour, then reinsert. With the Z10 being as "old" as it is, you may just have a bad battery -- try a new one. Others may have more ideas. Hang in there.

Also try some of these suggestions:

If you get no LED at all when you plug in the charger, or remove the battery and replace it.... you have a hardware problem. If the light blinks, there might be life in there, that a reload of the OS can restore... but as was said your data is not recoverable.

Did you happen to save your contact to your SIM card? Or use a 3rd party app to save your contacts to an unencrypted SD Card? Or are your contacts synced to the cloud? Why not?

Thanks for feedback Maria, are you saying if I do a software reload I will be able to rtetieve my contacts?
Thanks

Darn I did not save my contacts silly but true. is there a recovery method outside of the reboot process to consider?
Thanks Ned

Thanks fro your comments and it may be a software issue but sad to say did not use sim card or other storeage silly but true
any other alternatives excluding rebooting it?
Thanks Ned
