- Issue
- Toshiba has identified that some notebooks manufactured in January and February 2000 may have a fault that could prevent the notebook from starting up. This fault has been reported on Celeron processor-base Satellite 4090 systems operating at 400 MHz as well as the Pentium II processor-based Satellite 4100 and Tecra 8000s operating at 400MHz only
- Procedure
PRODUCT NAME PROCESSOR MODULE Satellite 4090XCDT Celeron Processor Satellite 4090CDS Module at 400 MHz Satellite 4100 Pentium II processor Module at 400 MHz Tecra 8000 Pentium II processor Module at 400 MHz The over-voltage protection (OVP) on the mobile module daughter board (Rev504 only), shipped by Intel, malfunctions due to the narrow margin and sensitivity to noise, and makes the notebook inoperable. This issue affects logic external to the microprocessor. Affected notebooks can no longer be started and the DC-IN LED at the front of the notebook blinks. Intel and Toshiba have developed a resolution for this issue that has been implemented in manufacturing (Intel revised up the module to Rev. 505) and affected notebooks can be repaired relatively easily. Notebooks with the potential to show the no-boot issue would be in a serial range which begins with “Z9”,”10” or “20”. The serial number can be found on the silver product ID label on the base of the unit. Customers with queries regarding their Notebook should contact the: Toshiba InTouch Support at: 888-824-8674.
