Thanks for replying, merlot.
No he can't log on at all so made himself a new account. ditto his email account and none of his contacts are visible. He possibly had had to change all his passwords.
A local guy set up his new laptop and moved his files etc over but perhaps didn't explain properly how he could access everything. DH doesn't think this man is very bright so won't ask him back.
I just think he should be getting far more from both devices than he currently does and is too stubborn to ask for help.
