Just had this issue myself after replacing a motherboard on a Compaq 6200 Small Form Factor.As Paul said:Assett Tag: Serial NumberChassis Serial Number: Serial NumberBuild ID: Label on the bottomof the computer - BIDFeature Byte: Label on the bottomof the computer - FeatureByte. Case Sensitive. Do not include spaces. Includes every character on the label.
May have a '.y6' or something similar at the end. That IS included.The Build ID and FeatureByte are essential if the computer is ever reimaged especially for upgrades to Win 8. If those fields aren't filled out, you'll have trouble with reinstalling/upgrading Windows.Here's a picture of the labeling. Hope this helps!
Do the fans sound like they are going really fast? When you removed the memory and booted it up did you get any error beeps?Overall it sounds like either a dead motherboard or processor.
Like Jonathan4203 said, check your connections. Sometimes there is an additional 4 pin on the other side of the motherboard that is required for it to operate correctly, but easily forgotten if not dealt with often. If anything has dropped into there recently, something metal to be more specific, like a paper clip or a nail(I've seen it) there's a chance it got underneath the motherboard and shorted out one of the connections.The best signal i have seen so far for determining this is the fan speed.
If as soon as you start the machine the fans rev up really high and do not slow down, your motherboard is not controlling the fan speed as it should, which usually means it is controlling nothing. Dakota Dave wrote:We purchased 22 of the HP 6200 Pro SFF computers.
5 have failed so far. Everyone of them had the symptoms you described and everyone of them was a dead motherboard. The first one failed the first day it was setup in Jan.
The 5th one failed this morning. HP delivered a new MB in less than 3 hrs. I had it back up and running in 15 min.DazGRIT wrote:I still need to contact them, I've had a second one go, I was going to put it down to a bad batch, I wonder whether there have been manufacturing issuesHello,- Dakota Dave and DazGRIT, thank you very much for purchasingHP 6200 Pro SFF desktops. We do regret the challenges you describe.- Dakota Dave, once again we regret that there were some with defective motherboards and that recently one motherboard was delivered to you in less than 3 hours. Let us know if you required additional assistance from HP.- DazGRIT, let us know if you need assistance contacting HP in the UK.
I haven't seen alerts regarding this product but will continue searching and will report back if I find alerts or bulletins.Regards. I just requested a warranty replacement of this HP SFF 6200 motherboard as well. The unit has shut off without warning several times over the past two days. This last time it took a lot of work and troubleshooting to get it to finally respond and boot but even when the system boots, the network adapter and AMT do not work correctly. (Before removing the battery and RAM, the only thing that could be achieved was slight fan activity after connecting the power cord and then it would just sit with the hard drive light on.
No video, no boot of any kind.) Now it boots but without a network connection, it's not much good to anyone. Oddly enough, if the network device is uninstalled in Device Manager and redetected, it starts working again but nothing will bring back the AMT device, it is dead and that is likely what is causing the NIC to fail upon boot. No driver updates, BIOS or any other changes makes a difference. The system is faulty and cannot be used until the system board is replaced.
At least it's under warranty. As a business we have purchased perhaps 100 HP Pro 6200’s and the predecessor model HP Pro 6000, we have only experienced about half a dozen failures as described previously with High Fan Speed and no boot up/bios or anything. Usually removing the cmos battery and removing the non-hp RAM seems to bring the machines back to life.Is this issue due to the third party RAM we have installed? Is there a recommended RAM we can purchase? We intend to upgrade many of the machines to roughly 8GB but obviously don’t want to cause any further failures.
