Question about Dell Inspiron E1505 Notebook

2 Answers

Screen goes black when power cord is plugged in.

Screen goes black immediately after booting up....except when just using the battery. If I plug in the cord, the screen goes immediately black, yet it is clear the computer is still working. There have been no hardware changes. Any advice would be appreciated. Thanks.

    Thanks for the quick reply. I have the computer running right now on the battery alone and it is working fine as long as the cord is not in. I tried running it on supply alone and the display craps out again. So, as long as the cord is not in, it works as long as the battery will last (not too long). So, it seems the problem only arises when the cord is plugged in. Do you think it could be the cord somehow? Thanks again.

    oh well, the screen went black even just on the battery....any other tricks up your sleeve?

    It definately not the power cord. I am having the same issue. I have tried that and it must be the power managemetn system

  • johnquinn288 Oct 13, 2008

    I have the same notebook and same problem. Not long after this problem starting happening, my graphics card (ATI 1400x Mobility) starting failing. I sent it into Dell twice. They replaced the motherboard and video card. Plus they sent me a new power supply. It still had this problem. I reduced the screen brightness when plugged in and the problem went away. Not a great solution but at least I don't have to run off of battery. As for the graphics card, I still cannot watch movies or play games without getting a blue screen of death. Dell's tech staff are useless.

    Same model Dell laptop--same exact issue. Guess I am going to have to send it back to Dell. Damn it! Should have just bought an ACER at Wal-Mart.

  • donnatwitty7 Oct 28, 2008

    Same problem. But in my case I just brought a new power cord for $65 and about 15 minutes after I plugged it in my screen went Black. I can say however that before that happened my screen was flickering for months like it wanted to go out and I guess it just finally gave way. I think I may just need a new backlight for the screen because you can see that it is still working underneath the blackness. Will update everyone after I take to the same place I brought the cord from. I have to say the next Notebook I buy will be a Mac or anything but a Dell or Compaq. I have had nothing but one thing after another with both.

  • decembermay Mar 09, 2009

    My Dell Inspiron 4100 is doing the exact same thing, I've replaced the battery, and the backlight inverter board, no improvment. Computer runs well on battery, but screen gets bright and then goes black as soon as charger is plugged in. Charger will charge new battery when power is off; old battery will not charge and battery light on computer flashes 4 orange and 1 green light.

    I am having the same problem and I've tried everything. I'm a college student with finals coming up and cannot afford to be without a computer anyone have any clue as to how to fix this?

  • mjhmail Apr 30, 2009

    My E1505 screen works fine on battery, but on AC power it goes black. I have taken my battery out and right now I am typing this using an external monitor. I can just barely see this screen image on my E1505. Is it the mother board? What does a new one cost. This E1505 is 2 years old.

Start by checking the power supply with an ohm meter for the proper output. Anything higher or low than one volt means the supply is faulty and will need replaced. This could also be a battery issue, if a fail safe in the battery has engaged. Try removing the battery and see if it works properly on the supply only, if so, then the battery will need replaced. If these two check good, then I'm afraid the problem is with the power management system on the motherboard, and unfortunately the motherboard Will have to be replaced.

    Yes, I do believe it to be the cord. Also, try an external monitor with the cord. It's unlikely, but the video cars may have an issue.

SOURCE: screen goes black with power cord pluged in...

Did you check your power management settings?

Have you tried cycling through the monitor modes (Fn +F8)? THere are three modes. If you're on the presentation mode, video is being sent only to an external monitor, not your laptop screen.

I have power and lights but a black screen


If it seems like the laptop booted up all the way except the screen is black try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

If it does not seem like the laptop booted all the way but the screen is black try the steps below.


When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power 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 the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot 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 the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

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

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.


Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.


Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Remove the battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of the memory 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 on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Screen won't come on.


Screen won't come on when? When you first hit the power button to boot it up? Does anything ever post to the screen when you hit the Power Button? Or does it seem like it booted up all the way (you hear the fan running, you hear the hard drive spinning) except the screen is black?

My eee pc 4G surf won't turn on. It started having problems when the power cord was bumped - causing it to immediately shut down. Then it just stopped booting all together. I replaced the power cord and...


Most likely, either the power jack inside the machine (jack itself or solder joints) or the plug on the power cord was damaged; obviously the plug is only a few dollars to replace, the jack also only a few dollars, but much more labor intensive. My experience tells me it's probably the power jack. If you have any way to externally charge your battery and, using it, find the machine operational, that pins it down pretty well. When the external supply is used, the internal battery is supposed to be switched out of the load circuit and into charging mode.
