Hi Naim owners, I’m having a little issue with my Unitiserve. Some weeks ago my Unitiserve start flashing on startup. I opened it, changed the CMOS batter with the new one, connect it through VGA to HDMI adapter, and I could see standard screen: **Warning! CPU has been changed or CPU ratio changed fail…** **Press F1 to continue, DEL to enter SETUP.** So I pressed DEL, but nothing happening, I cant see anything on the monitor. Any suggestions? Best regards, Nole ---

Press the other Del key. The one at the top of the keyboard, not the one at the bottom next to the number keypad. ---

That is exactly what I did. This is exactly the keyboard that I have. Its the brand new keyboard, connected via USB, because it does not have PS2. ![image](https://d2ikyu8xyuibjx.cloudfront.net/original/3X/a/8/a872c9a03470a7977036a46507d95f659269db9f.jpeg) Any ideas? Best regards, Nole ---

I see some suggestions online that Alt Backspace pressed together might function as a Del key. You could try that. ---

I have a PS/2 keyboard and VGA monitor. When the HDX boots, I get this screen on the VGA monitor: I understand from other threads that I need to reset the BIOS to the Naim Defaults. It’s not clear to me whether I need to hit F1 to continue or DEL to enter SETUP. If I press F1, the HDX boots up fine and I get the usual screen on the front of the HDX (which is mirrored on the VGA monitor). The HDX appears in… ---

Hi @NeilS, thank you for the answer. Great tip and idea man. I will try it out tomorrow. I am too tired now, started working at 7 and now its 22, and a finished like an hour ago. I have to go sleep soon, otherwise my CMOS battery is gonna get empty 🙂 ---

Alright, @NeilS I did all according to your instructions. Now I have Naim Logo screen, but its stays there. Now 15 minutes for sure? Is this normal? Any idea? ---

No, that isn’t normal. What were the circumstances surrounding its last power down before changing the battery? Was it a proper shutdown from the front logo, or a hard off due to a power outage etc? Try doing a shutdown from the logo (if that doesn’t work, you have no choice but to switch off at the back), start it up again & see if it halts at the checksum error again. Regards Neil. ---

I pressed the enter and the screen changed for a second, it was something like “The system is curently…”, it was too fast I could not read it all… ---

So what happens if you try to shut it down (or switch it off) & restart? Regards Neil. ---

@NeilS sorry for late reply. Well, nothing interesting happening 🙂 Still hanging there at Naim logo on the screen. I always did shutdown my unit correctly. But I can not say that for my ex girlfriend. She might not 🙂 I am just out of luck with NAIM lately. My HDX have DISK error. I contacted local shop here in Switzerland and they told me that they have to send it to UK and that the total cost would be around 1400 CHF. I mean how replacing HDD can cost 1400 CHF? I guess if I ask them for Naim Unityserve, they will give some similar offer. I don’t know what to do. ---

Bin them. Its harsh, but they are very obsolete in compute terms. Get a little server hide it away somewhere and forget about it. Or use the chassis to build a modern server. Its just mini ATX boards in there. ---

Sure I ain’t gonna dump them. It would be a crime. ---

I add my contribution that could be useful: while working on Unitiserve I noticed that not all USB keyboards are perfectly compatible, in two cases Unitiserve did not receive the commands indicated on the keys but different commands, I don’t know the reason but this anomaly can be avoided by using old usb keyboards from the win xp or win7 period ---

Well then, give it to naim and loose circa 600 quid for a device worth 300 on the second hand market. You can get a whole lot of proper modern server for 600 quid. ---

I can understand your frustrations, especially as you have two problem units. The only other thing I can suggest you check is that you didn’t inadvertently disturb the SATA connection to the optical drive when you replaced the battery - the unit will not boot if it cannot detect the drive. Regards Neil. ---

@NeilS you are the man! That was it. I actually totally disconnected optical drive. I didn’t assume that it could affect anything. Thank you very much! Best regards, Nole ---
