Using Support Tools
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 computer or on the
Dell Support website at support.dell.com).
No timer tick interrupt — A chip on the system
board might be malfunctioning or motherboard
failure (see “Contacting Dell” on page 53 for
assistance).
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.
