Dell Precision 5510: My laptop is suddenly dead, cannot determine the reason

Tue, 18 Mar 2025 00:41:22 -0700

My Dell Precision 5510 from 2016 suddenly won't power on (completely dead).

It used to work normally until couple of months ago, since when it just wouldn't power on. No light on a power button, no sound, no fans spinning, no text on display.

Previously, there was no warning signs of any problems, except maybe for a power button, I needed to press it a little bit harder then usual, but that was the issue forever.

What I did so far:

Checked charger voltage, it is 19.4 V, very close to declared 19.5 V.
Wiggled cable, checked that the charger is fully plugged in
Removed the base cover, removed some dust around the fans (there was some built up, but not too bad)
Removed the battery and charger, pressed power button for 1 min
Attached battery back, without charger, still dead
Attached charger, without battery, ditto
Removed one RAM module (out of two), then removed the second one, swap their places, etc, no luck

Any suggestions how to proceed from here?

Hi @oldturkey03,

My battery connector have have 12 wires: 4 red, 4 gray, and 4 black (left to right).

When charger is unplugged, and battery connected to the board, on battery connector I read 11.8 V on red wires, zeros on all others:

When battery is disconnected, I cannot read any voltage. I tried to probe on the back of the connector and on the bottom:

When I connected charger, I noticed two LEDs below the touchpad started to glow for a second, then turned off again.

With charger connected, on DC connector on motherboard, I read 19.4 V (three red wires), 3.3 V (grey wire).

When charger is connected and battery connected too, on battery connector I read 12.6 V (red wires), and 3.3 V (first two grey wires). Other two gray wires are on 0 V. I don't know if this is expected or not.

LEDs I mention before turned on for couple of minutes, then turned off again.

My understanding so far:

Battery is fine
Charger is fine
Charger connector is fine
Battery is charging

Could it be that the power button is damaged? That laptop is fine, but I just cannot turn it on?

I was unable to fix this myself so I took laptop to a service. The repair guy said that the power button is ok, but the two controllers that are orchestrating the powerup sequence needed to be replaced and one of them needs to be reprogrammed.

Dell Precision 5510: Why can’t my Dell precision 5510 keep a charge?

Fri, 29 Apr 2022 07:24:32 -0700

My laptop’s battery kept getting worse and worse. Eventually it couldn’t keep a charge. Laptop would still run on AC power but it would randomly power off abruptly. I changed the battery. Powered up and it seemed ok. It said that it was charging. At one point it reached 100%. I kept it plugged in in order to calibrate the new battery. Then the original issues returned. I’ve also gotten messages that it doesn’t recognize my charger even though it’s the official one that came with my laptop. I updated everything and it happened again. Now it will not start for more than a second. There’s a blinking orange light near the trackpad but doesn’t blink a consistent amount of times. Any info is welcome. Thank you!

Dell Precision 5510: Where are the cpu and the gpu located? I need to re apply heat paste.

Thu, 23 Apr 2020 05:28:32 -0700

I recently bought a used Dell 5510 and it worked fine for the first couple weeks and suddenly it started getting hot below the top edge of the touchpad. I took the battery out and ordered a new one thinking that must be the problem. It was not, as it still was getting hot, too hot to rest your palm on it when typing. The seller recommended replacing the thermal paste on both the cpu, and the gpu, but I’m not positive where they are located.

Thanks in advance for any help.

Dell Precision 5510: Will the iFixit Battery work for my HP Precision 5510?

Will this iFixit battery actually work in my Dell Precision 5510?

Dell XPS 15 9550 and 5510 Precision 84 Wh Battery

I ask, because I bought this battery off Amazon, which was purportedly for the HP Precision 5510.

https://www.amazon.com/dp/B0FT2D532H

I returned it because an error in the BIOS stated:

"WARNING: An installed battery is not identifiable and this system will not charge this battery pack. Using an incompatible battery of a third party battery may increase the risk of fire or explosion.

Only Dell batteries should be use in Dell computers, and Dell batteries can only purchased through Dell. You can order an authentic battery at www.dell.com/batteries

Will the iFixit battery work?
