Thanks,
Now to get things straight in my mind.
To restart the up dates again I need a new battery. Will that correct the other problems eg security alerts to say my AVG needs up dating, and the invalid certificate, are they connected or 3 different problems.
I f I go to the computer shop what do I ask him to do. He has already quoted £99 to upgrade including setting it up, when I told him I could not afford it he said I could take the laptop in and he would give it a service for £30.
If the computer has 3 different problems it might be worth paying the £30, but if only putting in a new battery is the answer I'll go to another shop.
Another thing I have found another way into these sites by preceeding. How secure is this and how long can I use the laptop. What will eventually happen?
I must thank you for your help.
