Dell inspiron N5010 blank screen at boot Solved/Closed

Question

Hello, 

I have an issue with my Inspiron N5010 screen, it doesn't turn on at all when switching my laptop on, even when I try several times (maybe 10 ~ 20) switching on/off my laptop the screen never turn on but everything else is working like (Led indicators - Optical drive - the Fan) but I the processor indicator is led for 1 sec and then it turn off and the Power light just remains on.

I've tried the old method of Removing the battery/AC and holding down the power button for 60 secs and turning on the laptop by AC, but this method doesn't work in my case.

Now the only working way to get my screen to turn on, is to do the following:
1- I just turn on the laptop and leave it for 5 mins to warm up. then I switch it off and turn it on again. that's the only way I can get my screen to work.

Please if anyone encountered the problem before and fixed it. please I really appreciate any help you could do to me. because I cant just go in a meeting with my laptop turned on all the way in the bag to make sure that It turns on in front of my clients.

Thanks.

Hey buddy all are crap whatever the others are telling you. I had the same problem and only reason is your RAM. check them. one of them is not functioning properly or may be gone thats why it is not giving beeps for RAM failure as there is working one and due to failure one it is not able to start. remove or replace the defective RAM and your lappy will start function properly again and all dell technical supporters are only looking for money in your pocket not for help. Dont trust them. and really had a very bad experience of dell laptops but instead of going to dell service center I like to do it by self by taking part of it.. and no fear when youtube is here.. ENJOY.. :)

Hi AMRDYS,

It could be a problem either with the graphics chip on the motherboard or the LCD panel. You can try below mentioned steps and isolate the faulty part:

1.	Try connecting an external monitor to the laptop and check if you can get regular video. If you get video on external monitor follow step 2 and 3 else follow step 4.
2.	If you get normal video after connecting an external monitor to the Laptop, it indicates there is some problem with the LCD or any of its components. Take a technician's help and reseat the LCD cables once. You can check below mentioned link to see the steps on how to reseat the LCD cable:

3.	If after reseating the LCD cables the issue is not fixed it indicates the issue is with the LCD panel or the cable. Replace first the cable if the issue is not fixed replace the entire LCD panel.
4.	If you do not get video on an external monitor in step 1, it indicates the graphics chip on the motherboard is not functional and would require you to replace the entire motherboard.

Before you proceed for any replacement please go through the following link to check your computer's warranty status:

Hi AMRDYS,

Thank you for clarifying your usage details to us. As Inspiron is not a gaming laptop it might not be able to handle extreme graphics usage. However, the problem that you have reported might get fixed after updating the drivers. Try updating the Video Card Drivers from the below mentioned link:

Hi Amr,

Thank you for writing to us. After updating the drivers and the troubleshooting done so far it indicates the problem is with some hardware component in the machine. Although, the computer is functional but the video is not functioning as designed so it is a failure in some component. As suggested earlier do isolate the point of failure using the steps mentioned in my first post and get the parts replaced accordingly. If you need any help with Dell Part Numbers, do reply with the Service Tag Number of the system in a direct message (do not post the Service Tag in any open forum).

As for the small parts you have pointed to in your last post, I would like to clarify this computer doesn't have a separate inverter board. Please use the following link to see the disassembly of Display Panel:

ftp://ftp.dell.com/Manuals/all-products/esuprt_laptop/esuprt_inspiron_laptop/inspiron-15-intel-n5010_service%20manual_en-us.pdf

I wish the warranty on the computer was active I could have arranged for a part replacement. I apologize for the inconvenience.

Do reply with results.
