Modem Problems

Some versions of the Compaq Phone Centre will not let any other program access the modem. If you get messages along the line of "Another Program is Using Telephony Device", "Comm Port in Use", "Unable to Detect Modem", or "Unable to Detect UART", and your machine came with the Compaq Phone Center, then you need to close the Compaq Phone Center down.

Modem in DOS

The modem used in the newer Presario lines (4000 series, 2000 series, etc) is a winmodem, and is not currently supported for use in DOS, therefore there are no DOS drivers available for the modem. The only way to access the modem option in DOS games will be to run them through a DOS window.

"Spool 32" Error/Lockup with HP660C or HP855C

If when trying to print with the HP660C or HP855C, the computer locks up or you get a Spool32 error message, or when printing a fax from MediaPilot, it comes out completely black. The first thing to do is make sure that you have a bidirectional printer cable. You will also need to get hold of the latest version of the printer drivers from Hewlett Packard. The versions you need are as follows, -

HP820 series - Version 8.2 or later
HP850 & 855 series - Version 9.0 or later
HP660 & 680 series - Version 9.01 or later.

If this does not correct the problem then try the following,
  • Turn off the printer and disconnect it from the computer
  • Delete the old HP printer driver
  • Restart the computer
  • When the computer is back into Windows, reconnect the printer and switch it back on
  • Click on Start / Settings / Printers
  • Double click on "Add Printer Wizard". Keep clicking on Next until you get the list of all the printers.
  • Click on the "Have Disk" button and insert the updated driver disk
  • Carry on with the installation as normal
  • After the installation is complete the Status Monitor (or Toolbox) needs to be moved into the Startup group, as follows.
    • Right click on Start, select Open, then double click on Programs.
    • Double click on HP Deskjet Utilities, and right click on HP Deskjet Status Monitor (or Tool Box) and select Copy.
    • Right click on the Startup folder and select Paste.
    • Double click on the Startup folder, and right click on the HP Deskjet Status Monitor (or Tool Box) and select Properties.
    • Select Properties, and click on the Shortcut tab.
    • Change Normal Window to Minimised, then click on OK.

This should cure the problem

Note -

  • The printer will need to be switched on before the computer, otherwise you will get a communication error as the computer goes into Windows.
  • If you receive an out of memory message when trying to print, go to the WIN.INI file (Start / Run / Win.Ini), and on the LOAD= and RUN=, if present, remove the lines C:\WINDOWS\CPQWIN\HB\HBDMN.EXE and C:\QUICKEN\BILLMNDW.EXE. This will stop the Presario Gallery and Quicken Bill Minder from loading automatically, but will give you enough memory to print.

Monitor Volume Control

In order for the volume control feature of the Presario xx25 monitors to work correctly with the computer, it is necessary for the monitor to be powered on at least 8-10 seconds before the CPU. Try removing the computer and monitor from any surge protector or power strip that they may be attached to, and turning on the monitor first, then the computer itself.

3rd Party Video Cards

The volume control on the 1425, 1525, 1725 and FX monitors is a digital control. It sends its commands via two conductors in the monitor's VGA data cable. The corresponding points on the VGA connector on your 4700 series Presario accept this signal. A 3rd party video card would not have this functionality built in. Most times, it just means the remote volume knob ceases to function. You can still adjust levels with the software. In some cases, however, a 3rd party card can cause the volume to either drop or go full on with no way to control it. One possible solution is to turn the computer on and let it fully boot up BEFORE you turn on the monitor. This way the monitor's remote volume function will not be initialized and you may be able to use the software volume controls.

You can if you want, go to any Computer parts store and purchase a VGA extension cable. You will need to remove pins 4 and 11. This cable will be installed on the monitor cable and then to the card itself. The rest of the manufacturers cabling will remain the same. You will lose the use of the volume control knob on the monitor. If this is not acceptable, then you will need to remove the card.

Norton Antivirus and Onscreen Volume Display

Norton AntiVirus auto load feature disables the audio graphic display. If you would like to enable audio graphic display, you have to disable auto protect from option menu of Norton AntiVirus program, and load it through startup folder.

To do this, in the Norton AntiVirus program, click on the Options button, then the AutoProtect tab. Remove the check from "Load AutoProtect at Startup", then click on OK and then Exit.

Then create a shortcut to NAVAPW32.EXE in the startup folder.

  • Right-Click (with the right mouse button instead of the left) on the Start Menu.
  • Click on Open.
  • Double-Click on the Programs folder.
  • Double-Click on the StartUp folder.
  • Click on the File menu.
  • Click on New then Shortcut.
  • Click on the Browse button.
  • Double-Click on the Program Files folder.
  • Double-Click on the Norton AntiVirus folder.
  • Double-Click on NAVAPW32 (or NAVAPW32.EXE if you are showing filename extensions).
  • Click on the Next button.
  • Delete the text in the box and type "Norton AutoProtect".
  • Click on the Finish button.
  • Close all open windows and reboot the computer.

This moves the Norton AntiVirus AutoProtect to the StartUp folder, which loads it later in the boot sequence than the default.

You can also temporarily disable NAV autoprotect from the icon in the system tray. Just right mouse click on the icon and select disable.

Changing the hardware configuration (video or audio) will likely also disable the volume control via the knob on the monitor. The volume can still be controlled via the software itself; only the control from the monitor is disabled.

Touchpad Issues

Disabling the Touchpad

If you want to disable the touchpad, you must install a serial mouse.

If you use a PS/2 mouse, then the touchpad will use this driver as well, so as long as the PS/2 driver is installed you cannot disable the touchpad.

If Windows 95 detects the touchpad and installs the software, you must disable it. In Control Panel / System / Device Manager, highlight the Synaptics touchpad, click properties, uncheck the original configuration checkbox and restart the computer. If the Logitech Serial Mouse is not listed in Control Panel / Mouse / General, the serial mouse will not function properly when waking from sleep mode.

Impossible to Control the Touchpad

The touch pad does not have to be physically touched in order for the cursor to move. The touchpad will detect electrical discharges from your hand and respond to it. When you type try to move your hands away from the Touchpad or rest your hands on the User Guide over the touchpad and see if that helps.

If you go into the CONTROL PANEL(Click START, then SETTINGS) Open the MOUSE Icon. Open the TOUCHPAD TAB and their you can change the SENSITIVITY Click OK, If you do not have a TOUCHPAD Tab open GENERAL Tab and select OPTIONS, this will take you to the Touchpad properties as well.

Battery Meter

My battery shows ??? in Windows 95

Windows 95 has a built in feature to indicate battery status. Windows 95 places an icon on the taskbar in the Systray, this feature can be enabled in Control Panel under the Power Icon. The Compaq Presario 1000 series does not present battery information in a way that Windows 95 understands, so the indicator will always say 'unknown'. The Compaq Presario 1000 series units have a status panel (the small panel just behind the F8 key) which provides battery information. Check page 3-2 of the Compaq User's Guide for information on the icons.

Click START the SETTINGS, go into the CONTROL PANEL and click the BATTERY Icon. Half way down the Power Properties you can uncheck the "Enable battery meter on taskbar", then click OK. This will take the take the battery icon off the taskbar.

My battery meter is stuck

Remove the battery and AC Adapter for about a minute and then plug the battery and ACAdapter in the system and see if this will clear it up.

Voodoo3 Video Card Doesn't Work

The Voodoo3 video card has problems with the Compaq Presario computers with the onboard ATI video cards. This is due to the fact that the onboard ATI card can only be disabled within Windows. The Voodoo3 cards do not like any other graphics cards in the same machine (especially onboard ATI Rage cards).

There are 2 ways that may get you round this problem,

1. If you go into the BIOS (F10 when the machine is starting up), sometimes you can disable the ATI card in there.

2. Try disabling the card through Windows,

  • Click on Start/Settings/Control Panel/System/Device Manager.
  • Click on the + sign next to Display Adapters and Double click on the ATI Video Card.
  • Remove the Check mark in front of Original Configuration (Win 95) or Exist in all Hardware Profiles (Win 98).
  • Close all applications and restart the computer.

If neither of the above methods work, then there is no way of getting the Voodoo3 card to work.

Compaq Hard Disk Drives

A lot of Compaq hard disk drives are usually partitioned into two or three depending on their size. One or two DOS partitions and a small (12MB) non DOS partition.

This non DOS partition contains the BIOS setup utility and settings and other tools and is accessed by pressing F10 at start up when the cursor flashes in the top right corner of the screen.

The machine needs this partition information to run and so it is a good idea to make a back-up, particularly if you plan to "fiddle" with the hard drive at all.

A backup can be made using the "Create a Diagnostics Diskette" option from this very setup screen. It is very simple, two floppies are required (one labelled setup and the other labelled diagnostics) all instructions are given on screen and the process takes about 5 minutes. These disks are used to recreate the non DOS partition as below.

These disks are also available (in compressed a form) as sp7781.exe (Diagnostics) and sp2141.exe (Setup) from Compaq's website.

Creating Non DOS Partition

  • Boot from Setup disk sp2141.exe
  • Message states that there is no Diagnostics Partition, recommends there should be and gives the option to create one.
  • Accept this and you are prompted to reboot from the Diagnostics disk sp7781.exe.
  • Follow prompts to switch between Setup and Diagnostic disks several times, this takes about 5 mins.
