Reboot and run Dell Diagnostics if you can.

If you can, maybe try re-seating the cpu? the computer isn't that old i mean its 2017. I have a dell latitude d630 from 2007 and its motherboard is fine. if still nothing maybe you need a new cpu. Another thing you can try is hooking it up to an external monitor and see if an error message appears on it.

I wish I could, but it wont even turn on, just the lights as I mentioned above, I'll try and reseat the CPU. It's just weird and I cant figure out why it's doing it. It's almost like something's shorting out that's making it turn off after the half second or something.

I've never worked with precision  dell laptops so I did some research and found out that the cpu is soldered to the Motherboard for the 7710. So if it is the cpu, you will need a new motherboard any way. Did you buy it directly from dell or another vender like Walmart? If so does it have a warranty? 

I bought it directly from dell and the warranty expired last summer

Hi @Bob4689 . Did you end up figuring out the problem?

Thanks,

Andy

If you press and hold the Fn key whilst powering the system on, does the Battery LED light blink amber/white in a pattern?

If not, please try the BIOS recovery steps here

Let us know how you get on.

I had the same problem, and was able to solve it in a way I haven't seen on these forums, so posting this for others.

I first replaced the power switch board and then the motherboard, thinking that was the issue. The brand new motherboard had exactly the same behavior... before trashing the laptop, I figured I'd go through and just connect one thing at a time to see if the motherboard itself could power up - and in so doing realized that the entire issue was caused by the junction board attached to the palm rest that connects the fingerprint reader, card reader, and near field card reader to the motherboard. By simply disconnecting this board from the motherboard the whole system started working again, though obviously without the security hardware. I've got a new (used) junction board on order and may replace it, but honestly I don't use these features anyway so I might as well just leave it unplugged.

Did anyone find solution.

My dell precision 7710 is turns on power indicator and then blinks in 2 amber and white pattern. I'm not getting bios menu. Caps lock only blinks one at time of connecting power.

I tried hard reset, residual power drain and replacing rams. But none of them worked.

I bought this second hand a month ago. It was working fine and suddenly turned off yesterday and not turning on. I'll be thankful for your help.

I solved my issue with mine by leaving it on charge for a very long time this model draws so much that if the battery isn't charged it can't always start on its own it would appear.
