Same problem here. Once power down, it's almost impossible to boot up. But I always managed to boot it up by continue trying. So no more power down for 2 months. Once running, it's fine. Reboot for updates give no problems.
So lets hope no power dips for the next years haha.
But if anybody has the solution without replacing the board, please let me know.

To all,
I had the same problem of not be able to boot up. Using Windows 10 and Dell BIOS A11. I read all the messages in various forums for their solutions. Basically, the problem is not been able to get the Dell logo so you can go into BIOS and/or Boot setup. I saw all kinds of responses and for some they work and for other it didn't. Many complicated steps for something that I found (it turn-out) to be simple.
Here's what I did:
1.Follow the CMOS reset, clear NVRAM, and BIOS procedure (steps)-- Make sure to disconnect power!!!
a. Take out the coin battery and press the power button for 10 seconds to clear the CMOS to totally discharge it. Put battery back.
b. Locate both the 2-pin jumper plug for the password connector (PSWD), and the CMOS (RTCRST)-- RealTimeClockReset (look at the XPS user manual PDF--download for free).
c. Move both plugs to the left.
d. Connect power, press power button, and wait at least for 10 seconds. Turn power off.
e. Put back both plugs where they were before.
2. Now, to force a Realtime Clock Power Failure (5 beeps in your computer at power up--power on!)
a. This will hopefully get you where you can make some changes to the BIOS entries.
b. At power up press F2 and/or F12 (BIOS access and/or Boot setup)
c. With F2 you can make sure the date/time is correct , the hard drives are recognized, and the booting sequence.
d. This is what you really want...F12...Boot setup!! Here I solved my problem...and hopefully yours. What I did is to change the Boot Mode Setting from Legacy Boot to UEFI Boot. This made the Windows Boot Loader (WBL) take over the booting process and....presto!! I got my system working back!!!
e. MAKE SURE YOU PUT THE BATTERY BACK BEFORE PRESSING ENTER TO SELECT UEFI BOOT!!!
f. I had DELL BIOS A11 so I updated to A12 while in Windows before I rebooted for second time to see if I really got it working. Know what? I DID!!!! 8-)
3. This is assuming you don't have a real hardware problem with the hard drives, memory, video card, etc., etc.
4. While I got it to force a Realtime Clock Power Failure I was able (within the BIOS options) to run hardware diagnostics...which they all turn out OK. So there were no hardware problems with my system...yours..who knows???
5. Hope this help since the XPS 2710 is awesome!!! I'll hate to see a good system go to waste for just a simple fix. For some of the user I read that bought a MOBO maybe it was not necessary...maybe! Give it a try and let us know if it works for you. If it does, please pass it along to other forums so everyone can benefit...thanks!

I'm not an expert on this model but BIOS chips are generally classified as ROM (read only memory).
