T7500 Fan sound then 2soft beeps then less noise but no sign on monitors
This morning tried to boot up but..
T7500 Fan sound then 2 short soft beeps then less noise but no sign on monitors.
Left for a while but no change. Checked leads, all seem to be fine.
Power light is constant green, Motherboard light is on, no other lights show.
Keyboard lights flash and on as usual.
Tried to boot to USB recovery but nothing.
Any ideas please?

It seemed I wasn't getting anywhere, so I thought I'd try to Clone my original o/s drive again this time using True Image in another Win PC so that the drive wasn't alive with the o/s operating like before.
It still told me about the bad sectors and I had little hope that it worked.
Anyway I made it the boot drive in bios and had it as the only drive in the box and sure enough it booted.
All the pre bios stuff was still there such as the Fan Controller however it booted.
The Win ,logo with the black screen, then it died and a few minutes later came back with the white text that it is fixing the partition that wasn't the one with the o/s on it.
Maybe 15 minutes later it rebooted and there it was, all my original icons on the two screens !
tested it with HDSentinel and it came up as 'Perfect' and it was also okay in UserBenchmark.
It updated Win to 2H1 from 1H1 and now says all updates okay..
There is still a Win problem where I cannot type into many of the Win o/s admin boxes, like Search or Settings etc.
Just dead, however it is a Win problem not a disk one and I have searched to see how to fix.
One happy chappy tonight!

Changed mobo battery.
Mobo fan and graphics fx5800 fan still going.
Turn on - Power light green constant- then a few secs later 2 very soft beeps but no other action other than fan noise.

Removed and re-seated RAM and compress air clean.
Turn on and it did go through initial Dell screen and I have chosen Diag test as it had some errors.
It is going through the tests now so will let it run and see where it takes me.

It keeps telling me that it cannot find the drive.
I see it at the pre boot, I see it at the top of the boot sequence in bios but when I go to Disks in Bios, it is not there.
When I boot up, it says drives not found.
Obviously something I'm not/doing in bios.
Please tell me what it is !

no, it was working previously. the internal cabling should not be related.
Access the bios, and if the setting is ahci , try to set raid . or viceversa, and try to boot. it's a quick test

The only other option is ATA no raid

Sorry no I don't. I have noticed though that the data cables are plugged in the HDD 0 to 3 mobo ports NOT the 3 SATA ports.
Maybe that's the problem?

Thank you. I do appreciate you're help.
I'm out of office now (8pm Sydney), but will try in the morning.
I was going to do it b4, but a panel comes up to be very careful a it may require a reinstall, what that means.
So we'll see. Hopefully it will do it as there are not that many things left to do except some corruptions.

Well, it's correct that changing the setting would not allow windows to boot, if it was installed with the other option.
Same goes if the setting is bios instead of uefi , and the os was installed while uefi .. it would not boot.
I'm just thinking about some settings that would have been reset by the cmos battery failing, and may be now different vs they were before ( note the may, it's possible but is not a certainty unless you remember how they were ). the main ones would be ata(ahci)/raid and legacy bios/uefi.. both affect the system actually finding the os to boot if it was installed with a different combination.
Another thing to note... if raid is selected and actually used, the configuration data of the intel raid is lost once the cmos is gone.
Have you considered creating a bootable usb dongle to check / access the data on the hdd ?

Yes all the drives are MBR not EUFI.
I have checked the drive using the Acronis True Image Boot dongle and everything seems to be there, but it hasn't been actually booted up to yet.

I have spent days on this and have finally got to a better place.
I took a Win 10 x64 os drive out of another box and it has booted up fine in the T7500 and has been running well for a few hours.
I am still getting the loud fan noises and that is what I need to concentrate on now trying to fix.
I did the .. take power lead out, hold down power switch for 30 plus secs then re connect power lead etc. It worked once and since then it doesn't work.
I get the Fan Controller and other fan errors on boot just before I choose the Win 10 option.
Here is some info which may help.
The power switch is constant green. The PSU switch is constant green, front chassis lights are all off once Win is running.
On start up. At the Dell logo, the blue status line stops about half an inch in at the character C in Precision, then after 30 plus secs continues and then goes into the pre boot motion.
It finds the drive and stops a few secs after MPT boot found when the ..
Alert: Fan Controller and other fan info is shown.
I press F1 and it boots into Windows 10 okay.
The fan noise is the same the whole time it's running.
What is the next thing for me to correct the fan messages please?
Thank
oz
