Question Dell Latitude 5590, no power

[Schreiber147]

Hello hive mind-

The stats:

Dell Latitude 5590
8 gig RAM

From the story I was told, is that the user was typing on the system and the laptop just shut off. It has never started again.

I have tested the power cord and block. It is reading the right volts. I have already replaced the power jack, just in case.

I have also installed a new battery with a battery replacement cable.

I have also tried pulling the batteries, both CMOS battery and regular battery to reset the system.

Everything is still a no go. It seems like the system is not getting power.

Suggestions please. And thank you.

This sounds like a motherboard failure.

Do you know if the laptop had ever been dropped or physically damaged in any way prior to the shutdown?

 

[Schreiber147]

No. It wasn't.

Is there any way of testing the motherboard?

Is it worth replacing the motherboard?

Thanks for your insight.

There really isn't a way for you to test the motherboard. Dell could, but not something an end-user can do aside from swapping in a working one.

The worth question depends on the cost of replacement of the motherboard or the entire system.

Googling (dell latitude 5590 motherboard) provided info for motherboards as little as $29.99.

If you are doing the swap, it might be worth a fix for less than $50.

Ok. That is good insight. I'll need to think about it. Thank you.

Another question(s). I'm up for trying to replace the motherboard. It seems like a no brainer. With that said, with info on the board is: dell ddm80 la f411p.

When I look up that type on eBay or other places, it is coming up around $70+.

When I look up Dell Latitude 5590 replacement board on eBay, they are coming up around $30.

Do I just need to make sure the "i" is the same, or can I upgrade to a faster processor without checking everything else?

Here are some examples:

Thank you!!!

I'm fairly confident that you could install a variant with a faster CPU. But not 100% certain.

Just make sure your laptop model is specified and you'll be okay.
