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?

Regards,

Dan

After changing thermal paste I was putting components together and while installing the keyboard the ribbon cable for backlight was bent a little too much accidentally, now it had a small part of it that's seem broken, even though I tried to flatten it with my fingers, since then backlit won't work anymore and I get an error concerning touchpad when running the BIOS ' diagnosis, which I believe is normal since both touchpad and keyboard are connected to the motherboard using one ribbon cable (touchpad and keyboard work fine)

the cable is the far right one is the one for backlit :

Is there a way to fix it at home ?

Translation Arabic - English

The fan is very loud and annoying.

How can I fix the cooling fan on my laptop because it is very loud?

I think my laptop has a virus in it, which can not be identified by windows security. In “Windows security” - ”Virus and threat protection” - ”Exclusions”, the exclusions are adding to list without my permission. If laptop is not in use for 4 minutes, the CPU stars running at 100% and as soon as i touch mouse or type any button it gets back to normal work, also if the Task Manager is opened this “thing” will not occur (all works normally).

I was advise to (buy) install Kaspersky antivirus.

Do you have another option to deal with this kind of abnormality?

Thanks!))

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:

1. Checked charger voltage, it is 19.4 V, very close to declared 19.5 V.
2. Wiggled cable, checked that the charger is fully plugged in
3. Removed the base cover, removed some dust around the fans (there was some built up, but not too bad)
4. Removed the battery and charger, pressed power button for 1 min
5. Attached battery back, without charger, still dead
6. Attached charger, without battery, ditto
7. 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:

1. Battery is fine
2. Charger is fine
3. Charger connector is fine
4. 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.

I got an annoying problem with my laptop not turning on, just thr light of the power button turns on when i click, turns on for 3 to 5 seconds then shuts down.

The last time when it was working, i always get a message that says such this: the performance will be adjusted to match the power. I think the keyword wattage is presented. Also i think it cant recognize the battery, and it was not working and not charging that period. Also the if i am can remember, it also can not recognize the adapter, but still working with very bad performance, then suddenly when i try to turn it on, it shut down the problem appeared.

Also i think the power jack got a problem, because when i last time turned it on, it suddenly shut down, then i turned it on, it started to the logo then shut down again, one last time then the wont start again.

I hope you would help me!
