Will changing the drive letter of an HDD on one computer cause it to change on another computer?

I have an HP dv9500 laptop that was giving me some problems, so I bought two external HDD enclosures so that I could take out the hard drives and transfer the data to my new laptop. To avoid confusion with other external drives that I've attached, I renamed the two hard drives H: and P: on the new laptop.

After I transferred the data, I put the HDDs back into the original dv9500 and was going to run the restore disk. However, now it won't even power on, as if the motherboard has gone out. I had the motherboard replaced last August, so I really hope that's not the problem now!

I'm wondering, since I renamed the C: drive that hosts the OS on the new laptop, will it change the letter in the original laptop as well, causing it not to find C: in order to boot? Just trying to rule some things out before I write it off as a piece of junk. Any help would be appreciated!

No, each Windows machine you attach any drive to will allocate the next available drive letter (unless you specify otherwise). This will not affect a hard drive coming from a different computer. When Windows boots on the laptop (if you can get it working!), it will still be the C: drive like it was before.

The BIOS identifies bootable devices by the device's hardware details and the port (SATA, IDE, USB, etc.) it is using. That's sort of a gross oversimplification, but you get the point.

As far as it not powering on, is the laptop plugged into a power adapter? If the battery is dead and it's not plugged up, you're not going to see any signs of life until it gets some juice. If you have a power adapter plugged in, confirm it is working by plugging it into another laptop.

I wish it was as simple as the power supply. I actually bought a new battery and new adapter a few months back when it started acting up but it's not the problem. I'm wondering if there are any other problems that could resemble symptoms of a bad motherboard? When I try to power it on, the lights flicker, the CD drive sounds like it's trying to spin and then it chirps and goes off. All within a second's time. Any thoughts or should I just use it for parts?

then it chirps and goes off.

Are you getting BIOS beeps? If so, take note of how many and the pattern.

No beeps, just a quick and quiet chirp as it's shutting itself off. Doesn't sound like the beep it makes when I get the blue screen errors.

This may be a dumb question, but is "system board" the same as motherboard?

The only dumb questions are the ones you don't ask. :)

And yes, that's what is implied by "system board".

Having this moved to Internal Hardware as it's not an OS issue.

Thanks, when I tried to post originally, I only saw the OS subcategories with nothing below it. I think the site was giving me problems yesterday.

I'll ask my fellow staff members for assistance since your topic might be overlooked now that it's been moved.

Stay tuned. :)

Can you record the sounds it makes?

This may sound like a long shot but....

Reseat the Ram. I have watched 9500's do this and it's as simple as reseating the RAM.

Hopefully it is for you also.
