3-4 Troubleshooting and Diagnostics HP Omnibook XT6050, XT/VT6200
Swapping modules that may 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 system-off switch: this resets the notebook, so that you can
restart it in a known state.
