1 Beep, No Boot Up


Jul 24, 2017
Hello guys, I hope this thread is in the right section. If not I request the mods to put it in the right one. I've been having problems with my laptop and cannot find a definitive solution so hoping you guys can help

I have
Dell Inspiron N5010
Windows 7, i5

My laptop recently shut down while I was on it and when windows update was installing. It suddenly went really really slow, the cursor started blinking so I tried to shut it down. There was a windows update going on so before it shut down it said installing update the computer will shut down after update installed and then it shut down. I tried to boot it up again but it wont. Here is the specific problem

When I boot it up it shows the dell screen, beeps once and then goes blank with a blinking cursor top right and nothinf happens. I can press f12 or f2 to go into setup and it allows me to do that. It also allows me to go into BIOS screen when I press f12. When I try to run diagnostics from the f2 set up options the diagnostics starts but gets stuck on the "Running MATS Test" thing.

Once in a while it doesnt beep and progresses to the "starting windows" logo screen but stops there. Once I was able to actually get it started and it ran fine but when I shut it down it wont start again.

The fan runs when I boot up. i tried removing the battery and purging static by holding the power button for some time but to no avail. I also reseated the RAM but no go with that too. Online I found that 1 beep for Dell means a "BIOS/ROM error or failure" but I dont know what that indicates or how to solve that.

I must also mention that my laptop has randomly shut down before due to overheating but its very rare and never before did this happen. I also bought a new adapter and this problem happened the very next day.

So could this be a problem due to the adapter or did the windows update not happen properly or is it an overheating issue? Would I need to change my CMOS battery or flash the BIOS? Or is it worse like changing the motherboard?

Any help would be great appreciated
Try this....

Make sure you wait until the computer would be fully loaded before trying this, and not try it right away like you would to say get into BIOS. This needs you to actually be where you would be when Windows Explorer loads.

1. Press "Shift" repeatedly until the "sticky keys" window shows up.

2. Now click the the link there that will lead to the "Ease of Access Center".

3. Next click "Cancel" on the the bottom right corner of the "Set Up Sticky Keys" window.

4. From here you want to click "Control Panel" on the upper left corner (it should be right beside the "Make Your Computer Easier to Use" title.

5. Locate the "Computer Settings" menu and then choose the "Recovery" icon (make sure that your view of this is by either large or small icons for easier access).

6. Now click and open "System Restore".

7. Here you want to click next on the bottom right corner (a few times) until the button "Finish" shows up and then click it. (Just follow everything prompt that the window says which will lead you to recovering your previous system, in a certain time.

8. The computer will now do the work it needs to and then reboot.

If that doesn't work, you can try the following...

You can also try doing the Ctrl+Alt+Delete and see if you can get "Task Manager" to show.

If the "Task Manager" windows shows, then choose "New Task" and then type in EXPLORER. If the desktop shows up then you need to go into "Start", "Programs", then "Accessories" and finally "Command Prompt". (Or you can do a search for CMD.)

Make sure you load the "Command Prompt" with Administrator access. Then when it loads type in....


It will do a file check.

Thanks guys for your reply. Before I could try your solution webworkings I sent it off to get it repaired in a shop so I don't know if it would have worked or not. When I explained my problem the guy there said the issue was with my hard drive even before he opened up or checked anything. He then repaired it and it is working for now without any issues.

After getting it fixed I did a diagnostics test on Dell website and it showed Hard Drive error on that test. I did the test 2 times. Once my laptop failed the "SMART Short Self Test" and the second time it failed the "Targeted Read Test". Both of which indicate HDD error or imminent failure. Whatever the shop guy did must have been a temporary fix but I am happy my laptop runs for now. I am also happy that it was not a motherboard issue as it is quite expensive to get that replaced.

I would assume there is nothing I can do about these failed test beyond waiting for my Hard drive to fail and then to get a new Hard Drive, right?
There really is no way to 'fix' a hard drive yeah. However I really would suggest backing up all your personal stuff to a cloud account, external drive, or something similar. You don't want to lose things when the drive does finally go, which one never knows how quickly that could happen.

Do not wait for the HDD to fail before getting a new one, except if you don't mind losing data in the (old) HDD.
