Tell him to try that:

1) Click START->ALL PROGRAMS->ADMINISTRATIVE TOOLS->LOCAL SECURITY POLICY. -
This will open the Local Security Settings screen.
2) Click the + next to LOCAL POLICIES and you should see USER RIGHTS
ASSIGNMENT. - Click to highlight this and on the right-hand screen you
should see a long list of items. One of these items should be INCREASE
SCHEDULING PRIORITY.
3) Right-click on this and choose PROPERTIES. This should open the Increase
Scheduling Priority Properties screen.
4) Click the ADD USER OR GROUP button to add the account of the Power User.

Edit: it means he needs to put you in the power user group, too, if it's not the case yet. Otherwise replace 4) so that he adds your account.
