The monitor connected to the system is set to receive video signals from the DVI port on the video card and it is not getting a signal.

Possible Causes:

  1. Monitor is connected via VGA (Blue Connector). Fix by using the input select button to select DVI input)
  2. The video cable is not connected to the correct port on the system (Or not connected at all)
  3. The monitor is on, but the tower is not powering on or failing to complete the Power On Self-Test (POST). It the power LED on the tower is NOT on, or solid or flashing Amber then the tower is not posting. Flashing amber is normally a bad power supply, solid amber is the motherboard.

How do i turn off the HDD


What happens when entering the sleep mode is the drives will be turned off and the present state will be kept in memory until awakened. While the system is active the power scheme will prevent the drives from idling down after so many minutes with the never turn off setting applied.

With the turn off drives after the default 20minutes of inactivity that doesn't mean all drives turn off at the exact same time. I've never come across any reference for changing the power plan option for individual drives. But I can point you at the guide for the power plan settings with one instruction on drive settings to apply prior to entering the sleep mode.



hope that helps if not let someone here know.

Bluetooth & sound


Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
