Using Support Tools
No boot device available — No bootable partition on hard drive, the hard drive cable is loose, or no bootable device exists.
•If the hard drive is your boot device, ensure that the cables are connected and that the drive is installed properly and partitioned as a boot device.
•Enter system setup and ensure that the boot sequence information is correct (see the Dell Technology Guide on your hard drive or at support.dell.com/manuals).
No timer tick interrupt — A chip on the system board might be malfunctioning or there might be a system board failure. Contact Dell (see “Contacting Dell” on page 74).
USB over current error — Disconnect the USB device. Your USB device needs more power for it to function properly. Use an external power source to connect the USB device, or if your device has two USB cables, connect both
of them.
CAUTION - Hard Drive SELF MONITORING SYSTEM has reported that a parameter has exceeded its normal operating range. Dell recommends that you back up your data regularly.
