The reason I am thinking that controller might be stopping PC from starting is the blue screen that pretty much started this whole thread. I am re-posting the very first picture. It says "...your computer has been halted... I did not press that "any key" so it might be that controller is in the position of halting the PC, could that be so? Just guessing...

MOM,
Thanks for the idea to shortly disconnect X961.1 cable, tried it, unfortunately it did not change anything.

Thanks for the comments!
- controller/PC connections have not been changed (robot has been used for last 3 years without any changes to hardware/software/connections). I re-plugged all PC connections to same places.
- I re-seated both cards on PC motherboard, memory as well as SSD in the same slots, just to be sure
- I plugged in external monitor in the VGA port of video card
None of this has helped. After switching on controller, there is no sign of life that PC is even attempting to start (no lights e.g CD-ROM light, ventilator not spinning, external monitor says no VGA cord, no sounds that would indicate HW fault, no reaction to pendant or external monitor when shorting "PWR" pins on the motherboard. It's like after I changed CR2032 battery the PC is not switched on by controller in any way (while controller itself is spinning ventilator and blinking green & red lights).
Can a change of PC motherboard battery really take the life for PC? Before I changed the battery PC was always failing to startup on first attempt, always started on second attempt. Now PC is not showing any signs of life.
I wander if there is a way to somehow start PC independently of controller so I have opportunity to even get into BIOS?

correction: instead of "parallel port" I should have written VGA port

Dear all,
These are the actions I have taken so far but unfortunately they were unsuccessful:
- I checked if startup behavior is the same and it was (first time pendant dark, second time stalls on Cross 3 screen)
- I checked if I can enter BIOS with ps2 keybord
- I changed CR2032 3V battery to a new (did it with controller powered off, myself grounded, in about 15 seconds)
After battery change on controller start-up pendant would never light up (several trials)
- I located motherboard (SY-7VBA) manual from manufacturer and located PWR pins (see picture)
- I shorted the pins with screwdriver several times (different ways with controller switched on and also in sync when switching on controller)
- I even re-seated video card (in same slot with controller switched off) as that was reported to solve pendant not lighting up issue for someone else
None of this helped, pendant is not lighting up on controller power on, so I cannot enter BIOS
Super grateful if anyone has any ideas for the next steps:
- I assume I shall get screen with parallel port to get into BIOS
- Shall I short "RST" (reset) pins instead of "PWR"?
- Any other ideas?
-
pipo thanks!
Just got ps2 keyboard and will attempt to do battery change on motherboard soon. Regarding BIOS, I do expect to see this kind of screen (from KUKA documentation)...if it is just clicking on those options, sure I can do it. If there are more tricks that I should know, then yes, it would be cool to get some screens & advice Thanks.

Thanks indeed for your thoughts. I assume it makes sense to try to change battery first before doing clone and reinstall of KSS, right? So, based on your suggestions I will execute the following task list.
1. get pre-historic (PS2) keybord
2. change CR2032 batteries
3. power up controller, press DEL, go into BIOS, load KUKA DEFAULT settings, and chose SAVE AND EXIT, I have never been in BIOS hopefully its cool there
4. set correct time and date in BIOS, I have never done BIOS but there seem to be some KUKA documentation so let's see how it goes
///
5. get equivalent drive. I just discovered that instead of HDD, company who did refurbish robot has put in SSD! (Innolite EDC 40P-V 8GB). That is good news as presumably it will be much, much easier to produce copy of that.
6. do the clone. Will investigate how to do SSD to SSD clone
7. save original and put cloned SSD into controller PC and re-install KSS.
Before I do the above points I was wandering if restarting without batteries was a proper cold start attempt. Is there an option to do something with ColdStart.reg or Bootdisk files that I happen to have?
The more we get into details the more exciting this gets, as I have done none of this before

Is the green circled cap bulged ?
It does seam ok (see pic) but thanks for double-checking this direction of inquiry. Now I (and other users of forum) will know which capacitor to watch out for.

Also, I noticed that there are batteries on mother board, too. These have not been replaced for ~ 4 years, should I do that?

Hi,
I have run KRC2 (KSS 4.1.7) KR 150-2 for about three years on occasional weekend without any problems but a couple of months ago it started booting only with 2nd attempt. On first trial pendant was dark and red lights were blinking in controller. Power off/on always worked to boot controller on second attempt. Message "Buffer battery voltage low PM1" made me replace batteries but to my surprise problem with robot not booting on first power on attempt persisted.
I could have lived with that but yesterday much worse thing happened. I accidentally left CD (with just some robot code, no other software) in the PC CD slot before boot and obviously robot attempted to read it it on the start and I did two silly things: 1) I switched power off/on during boot, and 2) when pendant showed the blue screen about driver (see pic) I did not press any key as suggested but powered KRC2 down and up again. This resulted now in KRC2 not booting fully but stopping at "Cross 3" screen (see pic) with red & green lights blinking inside controller.
Disconnecting batteries and then booting a couple of times (my attempt at cold start) did not help. First time pendant dark as usual. Second time pendant did not go past Cross 3 again. All consecutive times of booting with batteries always stopped at Cross 3 screen and red & green lights inside cabinet. I assume that startup not working on 1st attempt and stopping on Cross 3 screen are two different problems but I cover it all here to get the status right.
I dearly hope it is some trivial thing I can do to get full boot again. Any advice much, much appreciated.

Hi,
I am new to robots, so I' d be super happy for anyone to direct me to the relevant documentation to solve the following problem.
I have KRC2 KSS 4.1.7 KR 150-2 K 2000 robot and I need to devise a very strange custom tool that I need to control by robot programming.The tool would have servo motor and I need it to be switched on at the start of toolpath and off at the end.
The interesting part is that I must be able to digitally set constant rotation speed with which the servo motor needs to turn e.g (120 RPM) on start.
The intended tool is complex to explain, the nearest approximation - imagine a drill made out of servo motor and we need to control the drilling rotation speed.I have not yet purchased the servo motor or any other hardware that may be needed for such tool, thus advice on that would be very helpful, too.
Please help
