The computer enters suspend mode immediately after POST (the suspend lamp turns on). Error 19 appears and the computer immediately turns off. The computer does not return from suspend mode, or the suspend lamp stays on and the computer does not work. The LCD is blank after resuming. Your computer does not enter suspend or hibernation mode. Action The computer enters suspend mode automatically when the processor temperature reaches a certain level. This is not a defect. Make sure that: The battery pack is charged. The operating temperature is within the acceptable range. Refer to Appendix A in the User's Guide. If these items are correct, have the computer serviced. The battery pack power is getting low. Connect the AC Adapter to the computer, or replace the battery pack with a fully charged one. The computer automatically enters suspend or hibernation mode when the battery power is empty. Do one of the following: Replace the battery pack with a fully charged one and then press Fn. Connect the AC Adapter to the computer; then press Fn. Check if an external monitor was not connected before the computer entered suspend mode. Do not disconnect the external monitor while the computer is in suspend mode or hibernation mode. If no external monitor is attached when the computer resumes, the LCD remains blank and output is not displayed. This restriction does not depend on the resolution value. With ac power, your computer cannot enter suspend mode if an IBM communication card is installed. A modem card cannot prevent suspend mode, however. Your computer cannot enter hibernation mode under ac power if either an IBM communication card or a modem card is installed. If your computer does not enter suspend or hibernation mode and IBM communication card or modem card is not installed, check if suspend or hibernation mode is disabled.
