| BACKGROUND: | Unfortunately, the T1100 does not have a POWER light. You can tell if the T1100 is powering on by either: - Text appearing on LCD; or - 'INT FDD' light turning on momentarily after about 20 to 30 seconds (i.e. motherboard trying to boot from diskette drive). |
| • | Discharged battery. If the battery voltage is below about 10 volts, then the T1100 will not power on. The T1100 will appear 'dead'. Not even the 'LOW BATT' light will work. |
| • | Faulty battery - cannot be charged above 10V. |
| • | Verify that the 'LCD/CRT' switch at the rear is in the 'LCD' position. |
| • | Try setting the 'LCD CONTRAST' control to it maximum position. |
| • | The LCD may have significantly deteriorated. Try shining a torch at the upper left corner of the display. You may be able to just make out some very faint text. |
| • | Via cable, the LCD plugs into a connector on the motherboard. Try reseating that connection. |
| • | Try the diagnostic procedure that is found in the T1100 Maintenance Manual. |
| • | Verify that the 'FDD SEL' switch at the rear is in the 'INT' position. |
| • | The internal diskette drive is a 720K one. You need a 720K sized boot diskette, not a 1.44M one. |
| • | Bad boot diskette. Verify on another vintage computer that your 720K boot diskette actually works as a boot diskette. |
| • | If the 'LOW BATT' light is on, then low battery voltage is a possible cause (results in low +12V to internal diskette drive). |
| • | The data connection between the drive and the motherboard is done via a short ribbon cable. Try reseating that cable. |
| • | The power connection to the drive is pictured at here. On both of my T1100's, I found that connection to be loose. On one of my T1100's, I also had to clean the pins (using a scalpel). |
| • | Faulty diskette drive. |
