You turned your Acer Aspire One off a few days ago and when you went to use it again and turned it on all you got was a blank screen but power was going to the machine?
Are any of the little indicator lights showing on the front of the machine? If not, the mains cable may be disconnected, or a fuse may have blown.
Why does fuse blow in Cadillac?
Fuses blow, in any application, when the current in the circuit exceeds the limit preset by the fuse selection. It is also possible, if the fuse terminals are corroded, for heat to be generated, causing the fuse to melt, giving the appearance of having blown.
Can you use normal AC fuse link in DC supply?
yes, but you must derate the voltage as DC arc across blown fuse is not self quenching as is AC arc.
Why not replace a fuse with a steel nail?
A fuse is used for protection. If you replace it with a nail, you give up the protection. If the fuse blew, there was a reason, and the fuse protected you from the results of what would have happened if it had not blown, like such minor inconveniences as your TV set getting blasted beyond repair, or your house burning down.
If the function range switch is set at 200 vac what will the multimeter read if a measurement is made directly across both terminals of a blown fuse in a 120 vac line?
With the meter on the voltage scale you will read zero volts across the blown fuse. From the bottom terminal of the service switch fuse to ground you will read zero volts and from the top terminal of the service switch fuse to ground you will read 120 volts. The multimeter will read 0
