SOURCE: dell deminsion 4700 when i moved it,monitor,mouse,keyboard quit.monitor briefly displays power safe mode.pressing any key don't help

When you moved your pc you probably knocked the graphics card loose. You can open it up and try re-seating it. Make sure you unplug the pc first and then press the on button for 10 seconds to clear out all the power from the power supply before opening the computer up.

Also, If you are using a KVM... Unplug the KVM's power cord for 30 seconds and plug it back in. That will reset it.

Acer pc and lg monitor blank screen says power save mode on start up, anyone know how to fix this?


Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU.
It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.

There are some things to think about when you install this.

1. Is the sub a dual or single voice coil?
2. What ohms are the voice coils?
3. Is your amp 2 channel or mono?
4. What are the ohms loads allowed by your amp?

I am going to assume your sub is dual 4 ohm and you want to get as much power out of your amp as you can. I am also assuming the amp is a mono channel amp. (if it's a two channel amp, you can bridge the channels)

Go from the positive of your amp and wire to both positives of the voice coils. Then go from the negative of the amp to the negative of both voice coils. You will have 2 sets of wires to your sub. This is called a parallel set up. This drops the load of one dual 4ohm sub to a 2 ohm load. The lower the resisitance, the more power is able to flow from your amp, giving your more sound. Make sure your amp is 2 ohm stable.

Hope this helps

Brand new volfenhag 15 1500 wattsblew on 1200 watt amp why


There are a couple of reasons why this might have happened. Subwoofers are finicky. I always recommend to my clients that you don't apply full power to your sub until you have had one week of playing it at low volume. This helps to condition the voice coil. When at full power the voice coils heat up rapidly. To go from cold to heat fast will warp the coil. The bad news is that this would fall under the "abuse" category for refunds. Then again, you might get lucky with a return unless you bought it from an individual. The other thing might be how it was wired. If your amp is 4 ohm stable and you wired to a 2 ohm load, it may have shorted something. But you would think that would be the amp. Not sure this answered the question, but just a few ideas to think about.

My monitor is in low resolution even i put it at 1440x900


Hello, maybe you haven't got a driver loaded for your graphics card. Windows reverts to low resolution by default if it hasn't got a graphics driver loaded so at least you have some display to enable you to see what you're doing whilst installing the relevant driver.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:


Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.


Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)
