My Dell D620 Latitude does not power on consistently and the problem appears to be worsening.
Pressing the power button brings on power light and the 3 Caps/ NumLock / Scroll Lock lights and you can hear the hard drive powering up, but the hard drive light does not come on.
The laptop then switches off about 5 seconds later. With repeated presses the laptop may power on normally. Sometimes, holding down the power button continually till it switches off and then releasing the button immediately it will power on normally, i.e. hard drive light comes on. However, this is hit and miss.
I have found this article: Article ID : 57947
I wonder if tis is related.Any help appreciated, thanks.
Welcome to the community
Have you tried the troubleshooting steps in the link you provided? There could be 2 things, either motherboard or keyboard failure. Please follow the steps and post back for the results. So I can guide you to the right direction.
Here is the link for the manual if you need to reseat the keyboard ; http://dell.to/KqR0sJ

I appreciate your reply. I have reseated the keyboard a number of times over the last month or so when the problem occurs. In fact, I just had a job to turn on the laptop, as I mentioned above, to check if there was any replies to this post. When I saw your comment, I powered down, removed all power sources and reseated the keyboard and the laptop powered on straight away.
I shall try to power the laptop tomorrow morning. I'll keep you posted. I guess this may point to a replacement keyboard. It would be great to take the guess work out of it though :-).
Hi. I tried to power on this morning and the laptop displayed the lights as in the symptoms above i.e. no HD light but you could hear it powering on then going off. Managed to get it powered on after about 4 or 5 attempts by holding down power button till it powered off i.e. about 5 secs and the releasing power button almost immediately on next power cycle.
Didn't have time to re-seat keyboard. Will see what happens later today when I return home.
Well, on returning home laptop didn't boot on first try. Re-seated keyboard. Didn't boot!
Then finally did boot after a few tries. Switched off and immediately went tot power on on again. Didn't boot.
Tried about 2/3 more times and the hard disk light came on as well but it still failed to boot. (This last scenario happens about, 10 percent of the time - forgot to mention this). Then the laptop came on.
Any thoughts, please?
One other thing, that may or may not be related is that occasionally the laptop doesn't reboot when instructed to, it switches off. Happens about, say, 10 percent of the time.
This morning laptop powered on immediately (as it should!). This is how inconsistent the problem is. I ran the DELL online motherboard test last night - no problems at all - all passed. I couldn't see a specific one for the keyboard. I also run a Dell diagnostics quick test in DOS from USB stick and this passed. Haven't done long test.
When the problem started, about 2 months ago, and started to re-seat the keyboard, things weren't quite so bad as they are now. I would get quite a lot of "positive boots". As I mentioned above, this seems to be getting worse.
Sounds like there is an issue on the motherboard. How many Memory sticks do you have? Try isolating the Rams (If you have more than 1) Try testing using 1 ram only. See if it will improve. If no go, possible motherboard replacement is needed.
I have 2 x 1GB Samsung modules. I will try your suggestion. Thanks.
Well, I took out both 1 GB sticks and tried a single 512 mb one. The problem was still there, unfortunately. I also have just run the complete full diagnostics, but it doesn't show anything as a problem - all passed!.
I'm guessing that the intermittent nature of the problem makes it difficult. Also when the test runs, it's running on a functioning machine. The problem is obviously before the running stage.
Looks like I'll have to persevere or look at replacing the motherboard. Thanks for your advice.
Yes you are right, it is really hard to troubleshoot if the problem is intermittent. You might consider replacing the keyboard first if we will base the problem to the first link you provided.
Feel free to post back here in our community for any concerns.
Well Elijah, it's a little while since the last post. However, a couple of days ago I located a secondhand motherboard on eBay and swapped out the old one and the problem is now solved. Yippee!.
