Invalid serial number hp. Select Advanced, System IDs, and enter the serial number from the service tag sticker on the chassis. Press F10 to save settings and exit BIOS. For desktop branding, customers need to fill the following details availble on the HP sticker of the unit. The message indicates that the serial number was not entered, or was entered incorrectly, after replacing the system board or other component. To resolve this issue, contact HP using the Contact Support tab at the top of this screen. The motherboard was replaced by an HP Technician due to a network connection not working. After he left and I turned on the system I get 'Invalid Chassis Serial Number'. The solution posted using the ESC button or F10 did not resolve the issue.

Provided that is the same series I am seeing, you should only need to make sure the hard drive you are purchasing: 1) Is a 2.5 inch drive (-- not 3.5 inch!) 2) Is a SATA hard drive. That is pretty much the most common hard drive for now-a-days computers, so there is a vast array of hard drives (with different capacities and from different manufacturers) which will fit your computer. There are no BIOS specific limitations that currently restrict the capacity for this kind of hard drives (that I am aware of). Word of advice, do shop around. Well, the SATA standard was designed so that it was “forward compatible”.

In theory, this should mean that the older original SATA controllers should be compatible with all of the current SATA2 and SATA3 drives (without taking advantage of the novelties introduced in the more recent SATA2 or SATA3, obviously). Still, often times, the practice has a few exceptions to the theory That is the case of some SATA controllers from VIA and SiS. Because of that, many hard drive manufacturers started making their SATA drives with a configuration jumper that restricts the SATA version to the one your controller uses. Although I never really had any troubles with running SATA2 hard drives on SATA controllers, as long as you make sure the hard drive your purchase has that configuration jumper you should be safe. Once again, excellent advice - Clear and concise and yet explained in full - Many thanks I have just purchased (waiting for it to arrive) a 750Gb SATA hard drive. I could have got a 1TB, but those available are all 12.5mm high, and I wasn't certain if this would fit (with or without a new mounting kit), as the existing drive is a 9.5mm high model. I don't suppose you know about memory for my lapto as well?
