Hi folks,
I have had MANY years of service from my WHS EX470, but during a recent power outage, but WHS crashed, and didn't come back.

Here are the symptoms:
- Several (as in countless) boot attempts.
- Front panel lights (L to R): #1) Blue solid #2) Blue solid #3) White then Red then Blue flashing (forever)
- No drive lights

Other than a few hiccups (had to reset all my backups two years ago), this thing has ran like a champ for many years.

I'm hoping get some help.

Could the bios battery be dead? Does anybody know what battery this takes?

I have not tried to do a Factory Recovery yet.

Thanks

Well, the good news is that I found the CMOS battery: It's a CR2032 if anybody is interested, and I did change it with a fresh battery.

The bad news is that the Health light (#3) is still just flashing blue.

Any other ideas would be greatly appreciated.

Alright, now we're having fun.
After an amazing discovery of my 3 WHS disks in a box of misc CD's from the past few decades, I fired off the Server Recovery disk on my LT.

Doh! After running through the first part of the process, and waiting for the OS to download to my server, I get an interesting message.
Apparently, the installation process does not run on Windows 10. It has restarted in Compatibility Mode, and I am going through the entire process again. Hopefully, it will be successful running in Compatibility mode.

Err

Here is a quick update.
I was able to find a old Windows XP laptop and was able to go through the Server Recovery process. Ugh, it was sloooow...
It eventually installed, and rebooted. I was able to RDP into the server, and I have connected a spare HDD via USB, and I am in the process of backing up all of my data. I finally called it quits at 4AM to get a few hours of sleep. When I left for work at 830AM, it was still copying. Hopefully all the data will copy clean on my my USB HDD.

I keep an old XP laptop (it will not take win7, no drivers) just for doing the server restores.
I have copied the contents of the two CD's into folders on the desktop (so it doen't have to come from the cd-rw drive) makes it a little faster.
It seems to take about 30-60 mins. to load then about the same time to get the 3 HP patches and The 170 windows updates +/-.

Glad to hear you were able to revive it. I have my server sleep every night so one of these days I most likely will be looking at a battery.
Thanks for the info and much Good Luck to you.

I have about 2 tb of data and the last factory reset and copyback took all night. But at least it works still.
