Verifying The Repair - HP Omnibook XE4400 Service Manual

Swapping modules that might be defective with others known to be good is generally an ideal way to
find the module responsible for the problem. A failure symptom is rarely caused by more than one
module, so you will not usually need to replace more than one to correct a particular failure.
After you replace a module, the notebook will normally be in a confused state and lock up when you
apply power. If this happens, press the reset button: this turns the notebook off, so that you can restart it
in a known state.
