SERVICE NOTES

CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.

1.As of January 1, 1999, all 300-MHz and faster Celeron and Pentium processors are shipped with the processor speeds preset. This preset processor speed will override any switch settings on the system board.

2.Compaq Deskpro EP CTO units are shipped with Compaq PC Diagnostics 10.27D preinstalled. This version fails to recognize the 22.6-GB Ultra ATA hard drive and fails the drive test when the 22.6-GB hard drive is installed. To correct the problem, download and install Compaq PC Diagnostics 10.28A or later from the Compaq Web site at http://www.compaq.com. The problem appears only when running Diagnostics, and does not affect the performance of the unit.

3.After February 23, 1999, all Deskpro EP units with the Intel Pentium II and Pentium III processors will be shipped with a new system board and graphics controller. All machines with a date code of x908xxxxxxxx or later will use the new system board (spare part number 118053-001) and graphics controller (spare part number 402125-001).

4.Two gaskets are included in the Deskpro EP Series units to minimize vibration caused by the speaker when played at high volumes. The gaskets are located on the access panel directly above the speaker and on the bottom of the slot cover closest to the speaker.

5.With added LED support for more accurate field debugging, an LED Error Code Table label has been added to the inside hood of the machine.

6.If the PC contains what appears to be a fan intake/exhaust mounting area on the chassis, such as the long option card support, do not install a fan in this area.

7.A Creative Labs SoundBlaster PCI 128V Audio Board with Compaq Premier!Sound (spare part number 167984-001) and audio cable (spare part number 149806-001) will be shipped on 440BX units with Windows 98 or Windows NT 4.0 and:

•PIII 650/100 and 700/100 starting 11/15/99

•PIII 500-MHz and greater starting 11/17/99
