Cannot read cd's written on nx9110 on any other machine
Hi there, I have a hp compaq nx9110. I have used the cd burner on the machine to write CD's with jpeg files. I cannot read these cd's on any other computer, not even another hp. Is there a fix for this?

Hi there , sound like it is a software problem , if you can only read it on that compaq , it may be the permision setting in the writing software , if you cannot change these setting you could try installing a different writing programme .

If you try to install from cd/dvd drive, your optical drive lens can't read data well and resulting to delay transfer of data or error installation.Try cleaning the lens with cotton or lens cleaner and try again. Or maybe you have bad installer.
ery adjusting your brightness via the function keys on the keyboard also under power settings see if screen is set to save energy when using ac power usually this is set to save power when on batteries it just might be reversed on your machine
Let me explain some things for you to understand what happened with the dvd drive.
A laptop (or desktop) dvd writter drive is actually build around 2 separate optical systems each specialised to deal with either a cd or a dvd type of disk.
A cd has normally around 650mb - 700mb.
A dvd has normally around 4,3gb - 4,7 gb.
But both disks have the sime size. So the larger capacity disk, the dvd has higher data density as related to the disk surface. Therefore because these disks are being read using laser diodes, each diode must be tuned to a specific frequency for each type of disk. A cd is read/written by a 860 nm diode (infrared) and a dvd is read written by a 630 nm diode (red). These are separate optic subcomponents (by the way, a blue ray disk and reader is called blue ray because of the diode that is used to read them, it's on 437nm and it's emitting blue light).
If your drive will read only cd's and fail to read a dvd then it means that the coresponding optic block for dvd reading has failed. The cd optic system will continue to function as it's not linked to the dvd part.
In this situations there is little to do to save your drive so you should consider the replacement or assistance in a service center for your problem. I'm sorry as we aren't able to fix this without having to dissasemble things and use some service equipment.
Hi there , if the main battery is removed the cmos battery will go flat , if its a small pcb mounted 1 you can short the contacts for a short time , if the cdrom is working it mains the 5volt supply is ok and you should be able to hear the hard drive spin up unless there is damage to the pins on the hdd or the adaptor or hdd is mounted wrong .
