Using with a laptop

try with an external monitor (connect an external via 15 pin's output of your laptop)
if it worked, monitor of your laptop is damaged and you can only take it to a guarantee center.
and if it doesn't work:
1- open back lid of laptop.
2- evolve the battery.
3- wait 15 minutes.
4- put the battery.
5- turn on the laptop.
and if it doesn't work, take take it to a guarantee center quickly.

Since you only have one external monitor port, you need to use a video spillter, this will allow you to connect two or more external monitors.

NOTE: This video splitter will only give you duplicated displays. Please check the link below:

Thank you!

try holding down the fn button and pressing at the same time the button with a small screen on it will do monitor switching

You have to connect the Dell to the Toshiba and then press the Fn key + one of the function keys eg Fn+F7(there should be a monitor symbol on it.)

Rate the answer if it helped you.
Thanks for using us.

Research to see if the tv is vga compatable. Not all tv's can be hooked up to a computer. Most tv's that can be will have a vga port, thus you will need a vga cable.(sorry don't have a pic, google it)

There are generic (well, platform-agnostic) and free utility programs e.g. indexed on VersionTracker, used for fan control (FanGUI, smartFan, etc.) and power management which should work without interfering terribly with that Toshiba utility. Even so, it's possible you'll need to take out a misbehaving power-saving daemon (using Task Manager or whatever.) That suggestion to fiddle with the sleep levels is reasonable; another component you might update or refresh to work in concert with those tools is the system BIOS, which sets the addresses for all those sensors where Toshiba's tools can get at 'em.
