Device maintenance and repair

7.1

Maintenance

To maintain high system availability, we recommend the preventative replacement of those
PC components that are subject to wear. The table below indicates the intervals for this
replacement.
Component
Hard disk drive
Fan
CMOS backup battery
SSD
The interval for replacement of the flash drives (SSD) depends greatly on the type of use. A specif-
1
ic interval cannot be given.
All drives are monitored with the software tools DiagBase or DiagMonitor on the basis of
their SMART status. As soon the SMART status of the HDD or SSD switches to "Not OK", a
message is sent in DiagBase or DiagMonitor, or when you start up the PC. You should then
back up your data and replace the drive.
