At my notebook I use UBUNTU 10.04 after regular updating I have got version ...37 and yesterday I update the system to the version ...38

Every day I switch off my notebook and for the last 2 version I have got the following problem:

  • when I switch on the notebook I must type the password and very
    often my keyboard is not active now ! i.e. I cannot type password
  • click RESTART does not help - the same situation
  • when I shout down it - it helps but yesterday I had to do it 5 times before I could type password

how can I solve this problem?

So I guess you mean Linux kernel, something like

Linux YOURHOST 2.6.32-37-generic #81-Ubuntu SMP Fri Dec 2 20:35:14 UTC 2011 i686 GNU/Linux

with version 37.

Did you remove the old kernels? I guess you're using grub. Does it silently boot up, or do you have an interception moment? If so, hit the key in grub, and move to version -36, as a first workaround, and boot the old version, until the problem is fixed.
