There's no need to reset your BIOS, only you do is to set in your BIOS Setup to boot priority like for example First Boot Priority is your CD/DVD Rom Drive, if you got some Bootable System Disc then the Second Boot Priority is your Hard Disk Drive. Good luck!

Is there any chance the video output is switched to feed the rear VGA connector? ie the screen is black due the video being routed away from the screen. Try hitting F5 key.
Can you hit the Delete key to try and enter the bIOS screen? (it may be another key such as F1 or F2. See your Toughbook manual)
Can you have someone make you a bootable USB thumb drive and try booting up with that?
Its also possible that the hard drive has failed, but usually the BIOS POST check will initiate and indicate a failed hard drive or bad RAM etc
Can you remove the 2.5 inch hard drive? Usually its accessible under a removable panel under the laptop.
Feel free to ask more questions.
Cheers,
Steve
PS have you tried the discussion forums on the Panasonic website?

Hi, i bought sdram for a laptop online, i scanned the computer first to check what i needed. i got the ram through, fitted it and now the computer just beeps and wont start, please help


If the RAM is not properly seated in the slot, this can occur. Check the RAM alignment and make sure they are pushed all the way into the RAM slot. Be careful because it should not take much force to push them in, and the notch in the stick will line up with the slot on the laptop.

Could be the RAM is bad or is the wrong type for you machine, which you can test using a boot disk and a program like Memtest86. http://www.memtest86.com/download.html

Also, some laptops will require you to confirm the new amount of RAM in the system BIOS so you may need to go in there after it's properly seated.

Want to reinstall OS on compaq tc4200. don't have passwords..


If the BIOS password is set, you'll need to return the device to HP/Compaq to get that reset. Only other option I can think of would be to whip the hard disk out and see if it'll boot from a CD at that point. If that is the case, you could theoretically put the drive in another PC, wipe it completely and then reinstall it. The machine will try to boot from HDD, fail and then boot from CD next.

I bought the proper matching two 1Gig sticks of memory to upgrade my 2G mHz TC4200. I installed them and it wouldn't boot, so I swapped back the 1G stick to the original 512mHz chip and it booted. Then I...


Ok, Rob, did you buy the memory from Compaq/HP? Or is it a 3rd party set (ie. Viking, PNY, etc.)? Sometimes, Compaq/HP computers are VERY picky about the specifications of the memory that the mother boards will use. 

If you bought them from a 3rd party vendor, I would recommend taking them back and exchanging them for another brand or even just another set of sticks, but, before we go that route, let's try something else. 

Install a 1gb stick and the 512Mb stick and then go into the BIOS and see how much ram is being registered there. If it reads all 1.5Gb of ram, then we know it is something else, if not, then we have somewhere else to look. 

Assuming the BIOS registered the full amount of ram, try removing the 512Mb stick and then boot the computer, enter the BIOS and see if it is reading the 1gb stick properly. Assuming it did register the 1gb properly, swap the 2 1gb sticks out and repeat. If it did NOT register the lone 1gb stick, try moving the 1 gb stick to the other socket, and checking the BIOS again. If that works, then swap the 1gb sticks out, repeat the BIOS check.
Assuming that after you swap out the 2 sticks and they both work as lone sticks, go back into the BIOS and look for an advanced page or an option to turn on a "Diagnostic Mode" or "Memory Test", and run the memory test on each stick- one sitck at a time, to see if there is a minor/major memory addressing issue, with either stick. 

If they both pass individually, then, try reinstalling them both together and check to see if you can reach the BIOS with them both in place. If not try putting the 512 in the 0 or first memory slot and the 1gb in the second slot, then repeat the memory test, swap the 1gb sticks again, and repeat the memory test on the second stick- (the thinking here is that if it is not the memory sticks themselves, perhaps it is the motherboard or one of the sockets for the ram that is bad).

If you can reach the BIOS with both 1gb sticks in place, but, not actually boot to the operating system, then it is possibly a timing issue- this SHOULD BE AUTOMATICALLY configured, but, if you are an overclocker or a "performance wonk" you may have changed a relevant setting in the bios that controls the speed at which the memory and the processor interact. Or it could be a problem with windows hardware monitor not accepting the changes to the amount of memory in the machine. To test this possibility try going into "safe mode" at boot up, after the BIOS screen/Compaq logo has come and gone.

If you can boot into safe mode and not into regular mode, it is a problem with something in windows. Sometimes, just booting into safe mode alone will fix it, sometimes, it is necessary to run the restore DVD on the computer to fix the problem windows is having/ or alternatively reinstall windows without running the restore DVD, using this method will usually fix windows, with out deleting all of your data. You might have to reinstall a few programs afterward, but, your pictures, mp3s, document files, etc. will still be on the drive. Running the restore DVD almost always deletes your data, so USE THAT SOLUTION AS A VERY LAST RESORT, ONLY AFTER YOU HAVE TRIED EVERY other option I have given you. 

Good luck, and hope this helps.

Missing boot manager


go to system bios (using F10 key on the start "Commanly") then press F9 for restore defaults, and insert the Bootable Vista DVD into the drive, it will solve your prob.. otherwise in bios mode make sure that all the drives (HDD & CD/DVD Rom) are properly installed.
good luck

BIOS password


Here is some stuff I found on the net: Some Toshiba laptop systems will bypass the BIOS password if the left shift key is held down during boot. Try using Toshiba or toshiba as the cmos password. (cmos passwords can be case sensitive) and this: ToneToshiba Notebook BIOS password backdoor 1 Here's some other helpful links: http://www.tech-faq.com/reset-bios-password.shtml http://www.freelabs.com/~whitis/security/backdoor.html http://www.pwcrack.com/bios.shtml Good luck!
