When i turned on switch dell vostro 230 it give no display and led colour is red


No Display, so does it seem like the computer booted up and is running except that the Display is black? Do you hear fans running, disk drive spinning, blinking lights or beeps?

I'm going to assume that in your case since you mentioned a red light that it is not booting up all the way. Therefore your problem is probably with the memory, the video card or some other motherboard issue.

Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Blank screen


Did it boot all the way? Do you hear the fan running, disk drive spinning? If it sounds like it booted but the display is black, try this:
When you press the power button do you hear fansrunning, hard drive spinning, lights on the computer, hear any beeps or lightsconstantly blinking, hear the DvD/CD drive click and the light on the drawer ofthe DvD/CD turn on for a second or two? If so the laptop is trying toboot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

No disiplay on the screen of the laptop and on the external monitor


No display on either? Does it sound like the computer completed the boot cycle? Do you hear fans running and the hard drive spinning?

What happens when you hit the power button? Do you hear any beeps or see any blinking lights? Does anything post to the screen during the boot cycle?

If the boot cycle completed and you see no display on either monitor, then your video card is bad.

My screen is black


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.If it seems like the laptop is up and running but the screen is not displaying anything then the issue is with the screen. Take a flashlight and shine it on the screen and look very hard and you might see the icons or something very faintly on the screen. If so, your LCD Inverter needs to be replaced. It is located at the bottom of the screen and covered by the strip that goes around the screen. IIf you don't see anything on the screen then try plugging an external monitor to the laptop. I can be any kind of monitor, even the old big fat crt's as long as it has a vga cable that can go into your laptop's vga port. If you see the image on the external monitor, that means your video card is good and the screen needs to be replaced. Sometimes you might have to hit the FN key plus one of the F1 thru F12 keys to get the image to display. The correct F1 thru F12 key will either say CRT/LCD or it will have the icon of a display on it. Press and Hold the FN key then hit the correct F1 thru F12 key. This will toggle the the image to display either on the computer's screen, the external monitor screen, or on both screens.

No display after reboot windows


If it seems like your system is running whereas you hear fans running, hear the hard drive running, see lights, heard the hard drive click during bootup, but there is nothing on the lcd screen then try the following:
1) Try hooking a external monitor to your laptop. It can be any type of monitor even one of the old style fat crt monitors as long as it has a vga cable to connect to the laptop. There is a sequence of keys you might have to hit to get the display to show on the external. Most times you hit the FN (Function key) and hold it while you hit the corresponding F1 thru F12 key that is for display. Usually the correct key will say CRT/LCD or it might have a display icon on it. If the image displays on the external monitor that means the video card is good.
2). Remove the external monitor and reboot the computer again. Now when it is done booting take a flashlight an shine it on the lcd screen. You are looking to see if you can faintly see the icons on the screen. If they are there but barely visible then the LCD Inverter is bad. The LCD Inverter is located at the bottom of the lcd screen just above the keyboard and the Strip around the lcd screen covers it. You'll have to take the lcd apart to get to it.
3) If you don't see anything when you shine a flashlight on the desktop, then the lcd screen has to be replaced. However, sometimes the cable on the back of the lcd screen has come aloose or just needs reseating, so unplug the cable and put it back then see if it shows an image.


Read Below if it is not booting at all when you press the power button.
Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

Will not start the boot up process. Only the battery, ac, and power light on.


it might start but you may not see anything on your screen which may indicate a problem with your display, back light or video driver.
look for the hd light see if it is blinking, if it is blinking it is possible that the problem is the display.

do you get any image whatsoever at boot up? any message? any first screen? what does it say?

if in fact the pc does not boot up, it could be your motherboard, your cpu or your memory, if that's the case usually you should hear a secuence of beeps, do you hear any? what secuence?

can you try booting from a bootable cd? dowload knoppix and try to see if you can. if you it might be a problem with your hd.

post back with your findings.
