Pavilion 5255 - Modem Problem
If you get problems with your telephones (ie phones ringing, not being heard, not being able to hear callers) when you plug the computer's telephone cable in, then there is an adapter that you need to get from HP. Its called, you guessed it, a telephone adaptor and this will solve the problem.
If you have problems and need to reinstall from scratch, simply place HP Recovery CD in CD-ROM, switch off machine and wait 20 secs. When you reboot, it boots from the CD ROM taking you straight into the Recovery CD Menu.
DOS CD ROM
The machine that I have seen had the CD ROM and Sound set up in MS-DOS mode but watch out the drive letter is M:
HP Pavilion Boot Disk
There is a directory called DOSBOOT on some Pavilions. This includes an option to make boot disk which does the following,
From DOS Prompt type:
MS Works v4.0 and Small Typing Area
The problem is that when in any Word Processor you can only get about 7cm of the typing window. The fix is to go into Start Settings Printers and remove the Generic Text Only Printer and replace it with a standard windows type eg. HP Deskjet 500.
Entering the BIOS on an HP 3120
To enter the BIOS on the Hewlett Packard 3120, then hold down the CTRL+ALT+ESC keys as the machine is starting up.
6370 TV Not Working
The Pavilion 6370 has the capability for T.V. output. If you reset the BIOS defaults, it puts the TV settings to NTSC (American standard), which isn't compatible with UK televisions. To get round this, go into the BIOS, into PCI Configuration and change the setting from NTSC back to PAL.
6000 Series Recovery CD
If when you run the recovery CD, the hard disk doesn't have a partition on it, the recovery process assumes there is a problem with the drive and advises you to check the cables and use FDISK as necessary.
However when the Recovery Process runs it alters the drive letters, as follows,
So, if there is no partition, it makes the RAM Drive C:, and when it tries to extract the DOS Utils to the RAM Drive D: it cannot find it, so it doesn't copy the files, leaving you at a DOS prompt with no FDISK program.
To get round this log onto the A: drive, and type,
The DOS Utils will then be extracted to the root of the RAM Drive, and you should then be able to run FDISK, etc..
HP Diagnostics & Recovery CD Refuse to Run
On the motherboard on these machines, there is a flash EPROM, which contains information about the machine, such as the serial number and software build. This EPROM is unique to each machine, so if the motherboard is replaced then the EPROM needs to be flashed or the Recovery CD and HP Diagnostics will refuse to work.
There is a way round this,
This will create a bootable floppy disk to flash the EPROM. This disk will only work on the machine it was created on. When you run it, just follow the onscreen prompts (it will ask you for the Model No, Serial No, etc.).
BIOS Update Utility
Similarly there is an option to create a BIOS Update Utility in case the BIOS on the machine gets corrupted. Follow the same instructions as above, but at the M: prompt type in
6350 - Locking Up/Not Shutting Down
If you ever get the above problem, go into the BIOS and change the Power Management from Customized to Disabled.
6340 and Direct 3D
It would appear that the onboard graphics card of this machine (and probably the rest of the range) only support hardware emulation of Direct 3D. This can be proven by installing DX6 and using the diagnostic which comes with it.
6405 "Display Settings Correct?"
After turning on the HP Pavilion PC, just before Windows loads, a message will appear on the screen asking the following:
The monitor will then go into suspend mode (black screen) and the system will not boot into Windows.
The issue is caused by a game or application that changes the PC's default display properties (such as the refresh rate). To clear this, follow these instructions,
