Unless lenovo does things really different, the bios doesn't know what case the motherboard is installed in. After a great deal of frustration and time, I was finally able to obtain a replacement motherboard from Lenovo. I also have no idea you'd query it. The capacitors can sometimes hold a charge for quite awhile so removing the battery won't necessarily drain it quickly. It doesn't seem like that would do anything, but it may be worth a try.
Mac The serial number on a Mac laptop will be found on either the bottom of the case or inside the battery bay for laptops older than 2009. Such opinions may not be accurate and they are to be used at your own risk. When using the jumper you just disconnect the power cord, move the jumper to the clear position for a second or two and then back to the standby position. . I'd go ahead and see if clearing the cmos helps. Hey there, yes I do.
I have now installed the motherboard, and it is working. Does anybody know how to set the new Machine Type and Serial Number after a motherboard replacement for an H535? The other fields seemed to have valid entries. Net cannot verify the validity of the statements made on this site. You can find your computer serial number by examining the external case, or by locating it in the operating system. Find the serial number on the computer case Most computers have their serial numbers on the outside of the case or, for some laptops, underneath the battery. It's usually best to use the jumper to clear the cmos.
I'll check that out and let you know. That's the sort of thing is usually only available on workstation class hardware. As I now understand things from a ThinkPad Hardware Maintenance Manual, I may actually need to enter the numbers from my old motherboard. You have to be a little bit crazy to keep you from going insane. Hoping someone can tell me if this is possible.
What I actually use is a UserExit script that defines several functions to set some variables. It will be found on a sticker on the top, back, or side of your system, or underneath the battery on some laptops. However, my computer is an H535, which is technically in the IdeaCentre family of desktops--a completely different set of computers than the ThinkPad laptops. While you've found the solution. Much to my surprise, it reported that it had successfully saved the new information. Maybe the modules have that as the serial number. Net is the opinions of its users.
For example, in my UserExit script, I have a function called SetComputerName. In a few days when the option is available someone will probably choose your reply 6 as best answer for you and the post will be marked Solved since you cannot do this yourself. Find the serial number in the operating system If you've removed the sticker from the outside of your computer, or it's no longer legible, you can also find your serial number in the computer's operating system. I think they are in line with the Dell bios. You may as well mark your own post as Best Answer, since you're the one who solved it : Out of curiosity, what does the baseboard query return on your Lenovo desktops? I think they are in line with the Dell bios. I'm glad you found it! Basically as part of my computer name I use the serial number which is the service tag for Dell machines. It is not intended for consumer use, but it is out there, and I was able to get it.
Lenovo is telling me I need to find an Authorized Provider, but none of the ones on their list are in business or offering Lenovo support any more. The Serial Number on my old motherboard is different than than the one on my computer. Again, I am a bit astonished at how simple it was to actually fix the problem once I had the correct piece of software, which neither Lenovo nor American Megatrends apparently provides to owners, and it took hours and hours of research and searching to figure it out. Maybe the motherboard you received wasn't completely programmed by lenovo before being shipped. Similar to what I stated above, I am afraid to try that lest I ruin my computer, and I doubt it would do any good. And, perhaps even more astonishing was the fact that, when I rebooted, the double-beep and warning about invalid machine type and serial number had disappeared. The motherboard recently failed on my H535 outside of the Lenovo warranty but still under my credit card's extended warranty.
I just read through your post. That said, the changing of these text strings seems relatively safe. I've inherited a few Lenovo laptops unfortunately and I am trying to get them to work with my scripted naming convention. It did ship with the battery didn't it? It's inscribed at the end of the copyright data and above the regulatory warnings. George1421 wrote: While you've found the solution.
You could swap the modules and see if you can read the values then. From past experience I found that the Lenovo put their serial number different section of the smbios than the Dells so I had to check the manufacture field first to know which wmi call to make. Since the machine type and serial number is just a sticker on that case I'm wondering how the bios knows the difference. There is one for the H520, which may be the same, but I can't be sure. Dell A Dell's serial number is called a service tag. If necessary your manual should give info on the jumper location. Glad to hear you fixed it.
A Mac serial number is an 11- or 12-character depending model and year alphanumeric code. From past experience I found that the Lenovo put their serial number different section of the smbios than the Dells. Are the 2 systems you mentioned the same? Lenovo The serial number on a Lenovo laptop will be found on the bottom of the laptop or under the battery. Yea that is pretty much what I am doing. Even if no updates are available because it's a new model there's usually a download for the original bios.
