click Start, Help.

Not all third-party memory cards have been tested for use with the computer. Please
check the HP Notebook Web site (www.hp.com/notebooks) for a list of approved and
tested memory cards.
Test your computer’s memory with the DiagTools diagnostics. See “Testing the
Hardware” on page 113.
If memory doesn’t increase after adding RAM
Make sure your computer is using only PC-100 or higher memory (RAM) modules.
Modem Problems
If the modem seems slow
Check for excess static or noise on a line reduces the overall transmission speed. If
necessary, contact your telephone company about fixing this type of problem.
If you’re dialing internationally, line noise is often a problem that’s difficult or
impossible to eliminate.
If you have call-waiting, disable it—your telephone company can provide
instructions. It can cause symptoms similar to static.
Eliminate extra connections in the line. If possible, connect directly to the wall jack.
Try another telephone line, preferably one normally used for a fax machine or
modem.
If the modem doesn’t dial or no dial tone is detected
Check all cables and connections.
Connect a standard telephone to the phone line and make sure the line is working.
