I just bought this Inspiron 15 7559, used. The previous owner says it was working perfectly when he sent it to me.
When I received it (Oct 24), it would not boot up. I'd press the power button, and the power button and keyboard backlight would come on, and a fan would come on for about 2 seconds and then stop, but that was it. Also, the status light would alternate flashing white a few times, then amber. We took the battery and memory out, and did a power reset. Replaced the memory and plugged in the AC adapter, and the computer started up. So we put the battery back in, and everything was good.
Less than a week later (Oct 30), I was using the computer, just checking Facebook and email and such, and the screen went crazy and froze up. All I could do was do a force shutdown. But when I tried to turn it back on, it was doing the same thing it did when I received it. We tried what we did before, removing battery and memory and resetting power and all that, but it still will not come on. I ran the LCD BIST test, and the screen did come on and flash different colors, so I know the screen itself still works.
The laptop is still under warranty, so I could send it in. Or, the person I got it from said they'd give me my money back if they had to. I just wanted to find out if it was something I could possibly fix myself, before having to send it off for who knows how long, or returning it to the previous owner completely.
Also, I have submitted a warranty transfer form, but the warranty hasn't yet been officially put in my name yet. Is this going to be a problem if I have to send it in within the next couple of days?
You will need to wait for the warranty to transfer before you can send it in for repairs. The transfer could take 2-4 weeks to get the warranty transferred to your name. You can take the battery out,remove the power adapater and hold the power button down for about 30 seconds to 1 minute. Put the battery back in and turn it on. If that does not work it will need to be repaired under the warranty.
Well, as I did mention in my original post, I have already tried what you mentioned, and it did not work.
I'll keep looking at it and see what I can figure out. I guess whenever the warranty is transferred to my name, if I haven't figured out the problem, I'll send it in.
When you state "replaced", does it mean you have used a replacement memory or did you just reseat the memory modules? When the system led flashes, what is the exact pattern?
Good that you have isolated the issue not being the LCD.
Disconnect the adapter and battery and press and hold the power button for 30 seconds to release any static power. Then try connecting with the adapter only / battery only.
Press and hold the fn key + power button to turn on the system and it should initiate the diagnostics - check for any possible beep codes.
Try the BIOS recovery - this has helped resolve such cases - watch this video for more info - http://bit.ly/2frK2Pt
Use Rufus to create a FAT32 bootable USB - http://bit.ly/1mmhOE1 - and perform the BIOS recovery.
If nothing works, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records and I shall book a service call based on the system warranty. Also, kindly attach a copy of the invoice.
Let us know if you have any other queries.
