Troubleshooting and Maintenance
Troubleshooting Your Computer
120 Reference Guide
Memory problems
If a message says you are out of memory
• Make sure drive C is not running low on free space.
• If you’re using Windows 98, use the Memory Troubleshooter in Windows Help: click
Start, Help.
• If you are having memory problems while running MS-DOS programs, use the
MS-DOS or Application and Software troubleshooter in Windows Help: click Start,
Help (or Help and Support).
• 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 e-Diagtools diagnostics—see “Testing the
Hardware” on page 133.
If memory doesn’t increase after adding RAM
• Make sure your computer is using only PC-100 or higher RAM modules.
Modem problems
If the modem seems slow
• Check for excess static or noise on the line, which 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 difficult or impossible to
eliminate.
• If you have call-waiting, disable it—your telephone company can provide
instructions.
• 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.
