Troubleshooting and Maintenance

Troubleshooting Your Notebook

Memory problems

If a message says you are out of memory

•Make sure drive C is not running low on free space.

•If you are having memory problems while running MS-DOS programs, use the MS-DOS or Application and Software troubleshooter in Windows Help. Select Start >Help and Support.

•The full amount of RAM in your notebook is not available for running applications. A certain amount of RAM is used for display memory. The amount of display memory is shown in the BIOS Setup utility.

If memory doesn’t increase after adding RAM

Make sure your notebook is using only PC2100 DDR 266MHz or higher memory (RAM) modules.

If the notebook beeps but doesn’t start after adding RAM

You installed an incompatible type of RAM. Remove the module.

Modem problems

If the modem seems slow

•Excess static or noise on a line reduces the overall transmission speed of the modem connection. 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.
