Dell Precision 5510 completely dead, nothing happens when pressing the power button
I purchased a Dell Precision 5510 with a broken battery, which I thought should be an easy fix. However, also with the battery removed and just using the power cable, it had some trouble starting.
It sometimes showed me some lights, and the indicator lights were flashing 3x orange and 1x red. Also, the date would be reset, so I assumed the CMOS battery was (almost) broken. It did work after leaving it plugged in for a few minutes.
I tried to see if a new regular battery would also fix this issue, so I placed a used battery from another Precision 5510 in the laptop (which was working in the previous laptop). But since then, my laptop is completely bricked.
The laptop doesn't do anything. I've tried holding down the power button, tried the M-BIST test (holding down power button + M to check the motherboard), tried to use a different charger, but nothing happens. What could be going on?

So you have purchased about 6 year old laptop which is broken. Have you seen it running before purchasing the device. How you know just the battery is broken. You can find the Dell Precision 5510 service manual from here:
https://www.dell.com/support/manuals/en-us/precision-m5510-workstation/prec5510_pub/working-on-your-computer?guid=guid-9ccd6d90-c1d1-427f-9e77-d4f83f3ad2b6&lang=en-us
Was the battery fully charged when you replaced from other device.
What if you remove the battery and try to boot again. You can go to BIOS settings?
Does the second 5510 work again when you install the battery back.
How about bad CMOS battery:

I have had almost exactly the same experience. I had a dead precision 5510. No lights nothing. Convinced it needed a motherboard, I let it sit for about a month. Then I decided I would take a second look. I took out the RAM, SSD and disconnected the battery, the power connector and the video connecting cable from inside. I attached a USB power supply. When I did that, the light on the power supply went out. I then detached that and connected a different, non USB, power supply and then all of a sudden the LEDs started flashing. I reinstalled the memory, a SATA SSD and video and it booted with clock error. For sure I have a bad CMOS battery. I was intermittently clearing flea power by holding the power key for 30 seconds or so. Here is the weird thing. I then connected the video cable cover and changed to a NVME SSD drive and then again, no signs of life. I tried removing everything again and it would not start until I removed the WIFI card. It then booted (with clock error) so I reinstalled the WIFI card, SATA SSD, memory and video cable (not the video cable cover) and it continued booting into windows. So if anyone has an idea what is going on, I would love to hear it. Right now everything is working in it except I am not sure about the USB C thunderbolt port. I am going to leave it on and plugged in until my new CMOS battery arrives.

I also had the same problem. I solved it by disconnecting and reconnecting the CMOS battery. Unfortunately it's under the system board, the board must be removed to disconnect the battery.

A similar event happened on a completely different precision 5510. The computer was working fine. I turned it on after being off for several weeks. Nothing. Attached power supply and power light came on like I pushed the power button. Then LED started blinking 1 white 3 amber (bad CMOS). The odd thing is I had just replaced the CMOS weeks earlier. So I disconnected the battery, drained flea power and then the laptop had no signs of life whatsoever. Begrudgingly, I removed everything I needed to flip the motherboard, detached the CMOS and reattached, reassembled and then the computer came back to life.
