Unit Doesn't Power Up When Switched On; System Gains Power, But Computer Doesn't Run. No Disk Activity Or Beeps; System Beeps But No Picture; Hard Disk Drive Controller Failure On Bootup - Kontron ETXexpress-WPM User Manual

Unit doesn't power up when switched on

a) Check the front panel switch.
b) Check that the power cord is completely plugged in and power is available at
the source.
c) Check if the power supply cables in the chassis have been crimped or pinched.
In the case of a short, the power supply will sense the short and shut off. It will
also automatically sense the removal of the short and restore operation.
System gains power, but computer doesn't run. No disk activity or
beeps.
a) Check the speaker connection.
b) Remove all cards except video card. Turn on system, watch for picture, and
listen for beeps. If there is no activity, remove video card, turn on system, and
listen for beeps. If there are no beeps, replace CPU or test it in another
chassis. If you hear beeps, replace video card.
c) If picture comes up, replace each card one at a time. Faulty card will prevent
system from booting.

System beeps but no picture

a) Be sure monitor power is connected and monitor is properly connected to the
computer.
b) Check switches on video card. If correct, replace video card.
c) Strip the system down by removing cards until the defective card is identified.

Hard disk drive controller failure on bootup

a) If you are using an IDE hard drive to boot, ensure that the power connector
and the ribbon cable are properly connected.
b) Check that the drive is configured properly as master or slave by jumpers on
the drive.
c) Check that the HDD parameters are set up correctly in the CMOS Setup. (You
can use auto-detect hard disk to set the correct HDD parameters.)

Non Plug-and-Play ISA card is not functioning properly

a) If this card uses an IRQ, make sure that the particular IRQ is reserved to the
'ISA' bus in PCI/PnP setup in CMOS.
