Compaq Laptop - Will 5400 RPM Work?

I'm working on a Compaq Presario 12XL125 laptop running 98SE which came with a 6GB 4200RPM HD. HP (Compaq) live chat say the mother board isn't compatible with anything over 4200RPM and 20GB. I would love to put in the fastest HD I can.

My research has led me to a Hitachi 5K100 20GB 5400 RPM drive, but I'm concerned about the 5400 RPM compatibility issue (according to HP). Why would the motherboard care about the spindle speed? The HD interface is ATA100.

Does anyone have any personal experience with putting a 5400 RPM HD into a Compaq 12XL...?

You probably can achive that if you find bios upgrade.

I think the RPM of hdd doesent have anything with board.

You give him voltage and he starts spinning at 5400.

What is the full name of laptop?

The RPM's do not matter.

The BIOS may not be able to see drives bigger than 20GB but you MIGHT be able to get around that with a BIOS update but that might be hard.

The motherboard probably cannot handle some of the latest UDMA transfer modes but any 2.5" HDD will be able to slow down to an older/slower UDMA mode.

If the laptop supports LBA mode it should be able to see larger drives.

What are your full specs?

That machine sounds quite old.
