304 error reffers to keyboard error. Verify if your keyborad is properly plugged in, also verify if it's working (pressing Num Lock will turn on the led, pressing again will turn off).
If you plugged in an USB keyboard it won't work, it is necessary to be present an PS/2 keyboard.

SOURCE: how do i reset a cmos/bios pasword on a compaq

The power on password is a little harder to break in laptops than desktops and this tip may or may not help. Each computer manufacturer is different in how they set thier systems up. Disassemble the laptop down to the chassis where the RTC battery can be seen in its socket. Make sure that all power is removed from this device and remove the RTC battery. Let the motherboard sit without the battery in it for up to one hour. replace the RTC battery and reassemble the laptop. Do not put the main system battery in just yet, power on only with the AC adapter. Power the laptop up and if it asks for a password, just hit enter, if it still asks you for a password, type in "clear". If it still wants a password, then the only other option is to "short" the two contacts in the battery socket for the RTC battery, using a small wire to jump the positive and negative points in the socket, make sure nothing else is touched or you will Nuke your motherboard. With the battery contacts "shorted" power the motherboard up with the AC adapter, wait approx 1-2 minutes allowing the motherboard to post. Shut the board down, and follow the previos procedures for reassembly and powerup.

SOURCE: Error Message: F12=Network Service Boot

The BIOS may have reset to the default settings. Sounds like this was originally a workstation on a Corporate Domain Network. Access the BIOS and reset the boot order for CD first, then Hard Drive - you can even disable Network as a boot option. Power spike won't affect the Hard Drive contents, but it can reset a BIOS. Your win2000 should be intact.

Boot into Setup and run the TOOLS / PRIMARY HDD TEST / SHORT TEST.

If it fails, try another HDD.

If OK, verify Boot Order is Floppy, CD-ROM, HDD. Exit Setup.

Print Table 1 Low Level Format instructions from http://support.microsoft.com/kb/106419

Boot with a DOS disk that contains Debug. Run the Table 1 script. Turn V5000 Off.

Boot with the HP Operating System CD. XP install should now proceed normally.

Good luck.

Compaq Presaio S4200NX displays Compaq Splash Screen then a single continuous beep with but nothing else.


Hi,

Most Compaq desktop that exhibits 1 long never ending beep indicates Memory error; Bad RAM. Corrective measure therefore would be replace and test.

You can try removing the memory and cleaning the gold pins with a pencil eraser and try again. If this doesn't work, guess you're back to replacing.

Good luck and kind regards.

Laptop Boot Problem


It seems all Compaq laptops are infected by this problem. If you are sure that the AC port and the AC adapter is working? Can you hear the laptop trying to boot? ..e.g. Hard Drive spinning up, Floppy Disk Drive noise, etc.. if so ...Try hooking up a external monitor.. Does it smell like anything has burnt? (Call for service) Is there anything that sounds loose when you shake it? (Call for service or you can to open it?) Try booting your laptop from a bootable floppy if you have one. Or use Compaq's Recovery CD. But I doubt if you use recovery CD, you might lose data on your HDD. Which O.S. are you using? The Boot-up mechanism checks all the hardware before starting Windows. Some times floppy drive doesn't allow the laptop to boot further by either not responding or sending wrong signal.
