    Its up and running, THANKS.

    Needed to remove drives to even see memory cards. Only part that was even a little loose was the battery. But pulled memory out, then wiggled loose and reset every connection.

    Make sure all of your cards are seated properly. They can sometimes come loose during transit. Remove and replace video card and memory especially. Let me know if this works.

I have a asus x58l and it has a black screen. cant see anything


http://www.asus.com/Notebooks_Ultrabooks/X58L/#support_Knowledge

Don't know why I did that.

Asus Support. Those two words don't even belong in the same sentence. (Neither does Toshiba Support, or Acer Support)

Notice the large statement?

NEED SERVICE?

(In otherwords GOT MONEY?)

Rant over.

Janet,

The problem will be;
1) Graphics chipset
or,
2) Video Cable,
or,
3) screen Inverter,
or,
4) LCD screen

I'm betting it's the economical, and easy to replace - screen Inverter.

Laptop on, shine a bright flashlight at the LCD screen of the laptop; and shine at various angles.

See faint images?
Backlight is out, or screen Inverter is out.
90 percent of the time the fault is the screen Inverter.

Moving on........

A) Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
The VGA port is on the Back of the laptop.

This is a General example of a VGA port (Connector), and VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for VGA Cable example.
You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external VGA monitor.
IF not;

There are at least 3 display options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down, and at the SAME time; tap once on the F8 key.
The F8 key is the Display Toggle-Over key.

(User Manual indicates not all laptops, may use the same Function keys.
Whatever Asus.
The Display Toggle-Over key has LCD on it, surrounded by a rectangular line. Has a small monitor icon to the right of it )

Display on external VGA monitor? No?
Hold the Fn key down again, and tap once more on the F8 key.

No display on external VGA monitor, indicates a problem with the graphics chipset.

Display ON external monitor, indicates a problem with the;
1) Video Cable,
or
2) screen Inverter,
or
3) LCD screen

Perform the 'flashlight test'. No faint images go on to the external VGA monitor test.

Post back in a Comment.
We'll go from there.

Regards,
joecoolvette

(There are NO service manuals available, to the public.
Thank Asus for that. To procede though can be done.

This will require a partial disassembly of the laptop, to include removing the Keyboard, and Palm Rest Cover.

Together we can accomplish this if needed.

May do something I never do, and that is because of no Service Manual available. May ask you to buy a replacement screen Inverter, and replace it.
Need other information above FIRST.

Average cost is around $25 to $30.
The plastic frame in front of the LCD screen is the Display Bezel.

The screen Inverter is located behind the Display Bezel, and mounted to the bottom of the LCD screen assembly.

(Clip or a Philips head screw)

Average example,

http://www.ebay.com/itm/100-Genuine-NEW-Original-Asus-X58L-laptop-Series-LCD-Inverter-08G21VJ10107-/290873311574?pt=LH_DefaultDomain_0&hash=item43b9668156

Doesn't require removing Keyboard, and Palm Rest Cover.
DOES require removing all power. AC adapter (Charger), and Battery.

Acer laptop switched on light up on switch but no screen display


A blacked-out screen doesn't necessarily indicate a broken monitor. If the computer has run out of charge or is in hibernation or sleep mode,

if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.

To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.

Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.

Press the power button if the screen remains black. Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.

Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.

Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases. Some computers also use the "F6" or "F7" keys to increase screen brightness.

Hold down the power button for 10 seconds to turn off the laptop. Remove the AC adapter from the computer, close the screen, and then turn the PC over.

Slide the battery latch to eject the battery. Pull the battery out of its compartment.

Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.

Wedge the edge of the keyboard bezel off of the top cover. Work your way along the edge of the keyboard bezel to loosen it. Pull the bezel off the laptop.

Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.

Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken.
If the monitor doesn't work, the motherboard or video card might need to be replaced.

hope this helps

Have a new AOC 2436 VH monitor all hooked up and there is no sound. very frustrating can you help.


Vga does not provide sound over the cable. For sound to go to your monitor, you need to use the hdmi cable and only the hdmi cable. Also, make sure your computer volume is turned up.

Hi i just bought an acer aspire all in one z3731 and i dont know how to install the mouse and the keyboard


Welcome stoicacristi
You should just be able to plug them into a USB port which is located on the back of your Monitor/CPU. Unless you have a wireless version of a keyboard and mouse in which case you need to plug in the bluetooth adapter into the USB port. And don't forget to add batteries to your mouse and keyboard if they are the wireless type.

If this answer helps don't forget to give a thumbs up.

Cant display


need to find out if the issue is with the display, power chord, vga cable, vga card or the connectors...

1. disconnect all the cables from the LCD or the monitor, now just connect the power chord and power on the display and now see if it gives you any display

2. Try swapping the power chord with the tower (if its a desktop).

3. Try and change the VGA or the HDMI cable to test if the issue is with the cable or not, (the cable that usually goes from the back of the display to the tower)

If the issue is with video card then launch PSA on your Dell machine and perform LCD bist test.

To launch PSA:

1. Restart the system.

--------------------------------------------------------------------------------
2. At the Dell logo screen, press <F12>.
Note:
Some systems do not have an F12 key, to access the boot options you have to press the <0> (zero) key at the Dell logo screen.
--------------------------------------------------------------------------------
3. At the One Time Boot menu, press the <Down> arrow key to highlight Diagnostics, then press <Enter> to begin PSA.

--------------------------------------------------------------------------------
4. Write down any error codes listed.


Steps to perform LCD BIST after PSA is launched:

1. Watch the screen and listen for the color bar test prompt tones emitted by the PSA Diagnostics. If the screen is visible, one will see the PSA diagnostics draw a series of multi-colored bars across the screen. When completed, a prompt asking if the pattern was seen appears, accompanied by a brief series of tones.

2. Press <N> or wait approximately 30 seconds to fail the color bar test.

3. Watch for the LCD BIST color generation and listen for the beeps every 2 seconds that indicate LCD BIST is running.
LCD BIST runs for approximately 20 seconds, then stops. The 3-3-3 or 3-3-4 error code is then displayed when the LCD BIST is complete. If LCD BIST does not initialize, then the system may not have been upgraded to PSA version 3019.

I guess your computer is not booting.
  • Fix and tighten your RAM into the slot properly also clean the dust on the RAM with a soft cloth if any
  • check the cables for the HardDisk and CD Drive,they should not be lose
  • Take out all the USB connection [Flash/Pen drive,mobile,printer etc.]Try n change the Keyboard and mouse also.
  • Your computer Should Boot now.

Took cover off my tower and blew out the dust and when I hooked it all back up my monitor said no signal and light on my mouse just flashes


Lets tackle the monitor first: A no signal message indicates one of two things;
  • The video card isn't properly seated; (if the video card is on board skip to next step) just moving the video cable on the monitor to unplug it is enough to unseat the video card. Open the tower again and make sure the card is firmly in place.
  • If the video is onboard, the plug may not be firmly in place. Check the screws that hold the plug in place and see if they are turned as far as they will go; there's a chance the plug is only partially making contact giving you the no signal message
As far as the mouse goes, the only reason the machine won't recognize the mouse would be a faulty connection in the USB port. Assuming no damage was done while blowing the dust out, double check the USB port, maybe even changing ports to see if the mouse comes back. If your machine is anything like mine, space behind the tower can get kinda cramped and just putting it back into place and reconnecting the power cord can pull just enough on the lines to pull a line just enough to disrupt your connection.

Hope this answers your questions. Best of luck.
