XPS One 2710, power button problem

there are vast posts here and on every PC made by others on power problems,  and is normal in the PC universe. first I will do the most common.  (IMO I think AIO PCs suffer worse here, but not as bad as laptops)

IT is no real desktop PC that is for sure, (look inside SEE? not real more like laptop with missing huge battery.)

30seconds tells me that his the south bridge reset , per intels logic pure.   ending sleep.

• the PC is 8 years old why not replace the 7 year old spec life time battery with new RTC coin cell. NOW.
• the PC had w10 upgrade? HISTORY OF OS changes matter, upgrades do fail on vast PCs. did you?
• If yes, the drivers on your PC are wrong and sleep mode fails. (the endless story on PCs if ever)
• I will stop here,  I have 14 more tests to do but I stop here,  see how above works. out.

I can not guess, why, not with 20 parts that can fail, no me. but RTC sure.

NO OS stated, tell what is there now, and what it had new. 8 years ago. 

OS = operating system ? and version.

in search bar type winver   enter .    if windows.

and last , if RTC is ok,  is the hard power reset, this can unlatch chips and they recover, and resets sleep too.

any PC over 5 years old or more, all techs, check the RTC, or look daft, or waste all day doing NOTHING, tis a fact of life.  I use a voltmeter below 2.9vdc is BAD.  a $1 cure

Hi

Thanks for the reply, I replaced motherboard battery, with a new CR2032 and when I restart the PC the power button worked straight away ,but it beeped continuously, and shows me this

Reboot and Select proper boot device or Insert Boot media in selected Boot device and press a key.

Any idea how to fix this ? I am not sure what to do. Please help.

Thanks a lot

And I am on Windows 8. Sorry missed to mention this.

Count the beeps. They're an error code.

By removing the battery, you reset BIOS to the defaults. Reboot and immediately start tapping  F2 to open BIOS setup.

In BIOS setup, look for:

1. SATA 1 - Make sure your HDD is correctly recognized here
2. SATA Mode  - I suspect SATA mode got reset to ATA, so change to AHCI.
3. 1st Boot - Make sure your HDD is selected here.

Save the changes and exit BIOS.  PC will reboot automatically when you exit, hopefully to the desktop.

You can see all BIOS settings options on starting on page 159 in the XPS One 2710 Service Manual. Don't change anything in BIOS setup you don't know/understand.

Thank you Ron. Shall check as advised.

I powered it down after that beeps and when I try again to power up, it takes 30 secs or more again the way it took before changing the battery, any idea why that can happen ?

Thanks in Advance.

All in ONE PC desktop,  pricey new.

with a new battery , you need go into BIOS , and put the setting there correct for YOUR  PC.

power on and at the dell splash, hammer F2 key, or hammer F12 and do manually pick drive to boot.

F12 is first to see if will boot (manually picking correct drive HDD0), if yes, the we fix below next.

boot order is NEXT. F2. hammer this key powered on, bingo you be in BIOS (aka UEFI Firmware)

dell hdd sequence,  set to HDD0 (secure or not)

set the order hDD0 or SSD0 drive first, in the order.

have no other USB devices like thumb drivers or external HDD on USB ports present.!

setting that can be wrong in the F2 screens are:

turn off PXE in NIC section, pick enable but not PXE

make sure boot sequence is correct.

there is no battery to charge this is NOT A LAPTOP.  sorry. none.

that 2032 battery is NOT rechargeable if you found some other battery wrong and put it there , BAD NEWS.

the manual page 43 covers this.

the beeping is my guess, is 'CAN NOT FIND THE BOOT DRIVE)

PC came with 1TB hard drive boot. new.

you also need to look here and guess if the PC was legacy or UEFI secure boot enable.

1 of the 2 will work, try both  ,  the dead battery set this wrong, so we guess now, and 50/50 change bingo.

I and not sure how dell sells it with w8. what mode below, but one will work. trial and error. find.

if you pick MBR non secure boot, aka Legacy,  and the boot drive will tell you it is wrong with an error

paraphrasing, 'NO MBR here, or Secure boot drive only error"

i will test doing this worn on my Dell SEcure boot PC over yonder, next, and report back the error done wrong

mbr boot to secure drive. done wrong. for fun.. (its expendable my beater PC's)

done

it tells me done wrong , bad boot sector,.  black screened.

then it put the secure boot back in bios page

and boot ok, no problems seen

so toss the coin there, legacy or secureboot.
