I have read through previous posts regarding this subject but none seem to be similar to my issue. I have, for the past year, had some difficulty getting the power button to turn on. There are no beeps and I have used both with the power cord and without it.
Generally what I have to do is jiggle the laptop top or move it back and forth. This leads me to think there is a lose connection somewhere. It usually turns on but I should mention that I also usually turn off laptop by "sleep" not off. However, today I used "shut off" and had a very difficult time getting the laptop power button to turn the system on. It is totally black and definitely shut off. After hours I guess I jiggled the top in the right position and it came back on.
If you could share some thoughts about what the issue might be I would appreciate it. I didn't know whether to return it to Dell for repair or find a local repair person here in Pittsburgh. Obviously it is several years old and I don't want to pay a fortune to repair it.
Start by replacing the DC jack in the system - if you need a part reference, post the full model number (i.e., 7531, 7779, etc.).
Any more than that and "several years old" likely means you're better off replacing the system -- the mainboard replacement that would be needed will run you a few hundred dollars and on a system more than 2-3 years old likely means a replacement system is a better idea.
I have a 5758 model. Not sure what the DC jack is. I went online and saw someone on utube replace the power switch. Mine certainly has been flattened out and doesn't click anymore and I'm wondering if that could be the issue. I also had no problem this morning starting it in Sleep. I appreciate your suggestion.
Sorry I looked up what the DC jack does and I'm interested in why you might suggest that as my battery remains fully charged and if I disconnect the charger it will charge to 100%. Wouldn't that indicate that the DC jack is working?? Thanks.
