    I did re-check the BIOS settings after the reset and was able to save before the laptop froze. It still gave the same problem. I also tried flashing the BIOS with a newer one from Toshiba's website which claimed to fix the problem of the blue password screen.

    I have not gotten the password screen since, and this freezing only started happening after my initial reset to fix the blue screen password problem.

    The major components swapped out were hard disk, memory chips and dvd-rw drive. swapped them out with known good ones from a second laptop and got same problem with first laptop.

    Original parts worked properly in second laptop.

    Can't tell if I'm getting other problems yet, since the freezing does not permit me to do anything else.

    BJ and all others, thanks for the details. Still have not resolved the issues, but just to clarify..

    I did try everything offered by BJ, but still the same problem.

    Also, I can get past the POST and boot into windows vista just fine, then the PC locks up.

    I want to believe it's related to an overeating problem, since it tends to lock-up after being on for a while, no matter what screen I'm on. However, I don't see any temperature controls to adjust/turn off.

    Also, the fan on the CPU is working properly, I checked this. And this problem only happened after I short the 2 pins to remove the BIOS password.

    So as of rite now I'm totally stuck. Will appreciate any further assistance or ideas and thanks to those who are already assisting. You guys are what keeps me going in this techie world...

    Model is PSAD6U-00S00D.

    Also noticed that just before locking up, the speakers make some static type noise (while accessing hdd during windows loading). Then everything locks up.

    And the USB port does not recognise either a flashdrive or a usb mouse when plugged in.It says that the device was not recognised (these devices work fine in another laptop).

    My apologies. I am new and did not realise that this was a final rating. I was under the impression that this was a comment relastive to the immediate post...

    When you reset the BIOS you also reset the options inside the BIOS.

    The lockup can be caused due to incorrect/not set settings in the BIOS.

    Have you checked this first?! You should, it is the no1 rule.

    Hello Rajparm

    (01) Did this problem begin only AFTER you reset the BIOS password - or was it already a problem BEFORE you set the BIOS password?

    (02) If the problem began only AFTER you reset the BIOS password:
    Have you tried flashing the BIOS w/ the latest update (even if it's the same as the revision your BIOS was already at, it could restore your BIOS if it got corrupted)?

    (03) Exactly which major components have your replaced?

    (04) What other issues are you experiencing w/ this computer?

    * Please, post back w/ your answers and
    * any other info. you can provide (the
    * more details you can provide the better)
    * and we'll see if we can get this issue
    * resolved or at least diagnosed for you.
    * Thank you

Toshiba says this problem is happening with all their laptops and it is their problem from original programming---whether your laptop is in warranty or not, they HAVE to fix it at any Toshiba authorized service center FREE, and it only takes them about ten minutes. Had the same problem with mine and they DO know how to fix it right the first time so you have no further complications. As for Toshiba, WHY ARE YOU STILL SELLING THESE LAPTOPS IF YOU KNOW THEY ARE ALL FAULTY?!?!?!?!?!?!? They should be stopped from selling faulty equipment. Toshiba is a RIPOFF.

I am sorry to inform you that the only solution is to replace the system board. As a Toshiba Technician and seeing this problem over and over, most of the time when the bios jumpers are shorted it destroys the usb device circuitry resulting in immediate failure or failure in the very near future usually within 90 days. Check with toshiba to see if your unit is in warranty by going to the Toshiba website and calling their depot repair hotline.

Hi Rajparm

Thank you for answering the questions I posed to you. That is very helpful.

I want to be sure I'm understanding the symptoms you're experiencing correctly

(01) You never get past POST b4 the system locks up, correct?

(02) In other words, you never get to the point where the operating system starts loading, correct?

(04) Disconnect power from the laptop and remove its battery(ies).

(04) Disconnect all changeable hardware except the hard disk and RAM. (disconnect your optical drive and ANY devices connected to any PS2, USB, IEEE1394 (firewire), eSATA, external video, etc. ports.

(05) Disable your wireless radio using the laptop's wireless radio switch or button.

(06) Switch off blue tooth, too, if it is also on a switch (may be on the same switch or button as the wireless radio).

(07) Remove any PC Cards

(08) Reconnect A/C power to your computer (***do not*** reconnect its battery(ies))

(09) Power up your computer and enter its BIOS.

(10) Restore the BIOS to its "Factory Default" or "Optimum" configuration (you may have one or both choices or similar).

(11) Reboot and see if the problems persist.

(12) If they do, enter the BIOS again and disable wireless radio; set it for no optical drive; disable blue tooth; disable IEEE1394. IOW, disable all hardware functionality that is not critical to the basic operation of your computer...

(13) Continue w/ this process of elimination - bringing hardware function down to a minimum. This will enable you to rule out these hardware and functionality.

(14) If the problem persists, flash the BIOS again. Sometimes it doesn't "take" the 1st time. Make sure you follow the instructions **verbatim** (particularly w/ respect to backing up the BIOS **b4** flashing it and the steps that should be taken **after** flashing the BIOS).

(15) Please, post back here w/ the results and any other observations or comments you have.

Thank you,
BJ @:)

    Hello Rajparm

    If you'd like to remove the Thanks for Trying rating you assigned to me or upgrade it to a Helpful or Fixya, I would be happy to continue to work w/ you on this problem.

    In future, please, don't assign a rating to any of the expert's contributions to helping you solve your problem until you are ready to close the problem.

    Trouble-shooting an issue like the one you're experiencing is a complicated one. It WILL NOT be solved in one fell swoop. Determining the cause of the problem will be a process whereby the expert(s) will ask questions of you AND ask you to try certain things THEN you report back to the expert to let him/her know the results and your observations. This process will continue until your issue is resolved or diagnosed.

    I had asked you a number of questions which you did not answer until you returned days later at which time you assigned a negative rating to my solution THEN asked for mor help.

    The answers to my questions that you provided in fact would have changed my approach to your problem entirely.

    Be patient w/ the experts and tell them ***EVERYTHING*** that you know about the problem. Otherwise we are essentially working "blind". Assigning us negative ratings because we don't know what you arent' telling us is unfair.

    Thank you

    That's OK, Rajparm. I understand your confusion. It is shared by many who seek help from experts on FixYa. We experts are hopeful that, in time, the FixYa rating system and how to use it will be made more easy to understand for everyone.

    For now, just remember to keep a problem open by not assigning a rating until you've given the expert(s) who have volunteered to help you sufficient opportunity to answer your question or to resolve or diagnose your problem. Quite often it will take posts back and forth between you and the expert(s) over a period of time b4 the conclusion is reached.


    I'll be able to post once or twice during the day today but I need to work so, will be able to post more in depth this evening (Pacific Standard Time).

    (16) If you think there could be an overheating problem, find a floor fan (a fairly powerfull one, if possible) and open the case to your computer. Turn the fan on high and direct the air flow into the case.

    (17) Boot the computer into SAFE MODE and monitor it for a while. Let's see if the problem shows up. Monitor it for 30 minutes (after the computer has been powered on for one hour or more already).

    (18) If you were 're unable to induce the problem in SAFE MODE, boot the computer into NORMAL mode and monitor it again for at least 30 minutes. As in SAFE MODE, don't do anything. Just let it idle.

    Another heat-related problem is when a component is borderline functioning and cannot w/stand the temperatures it should be able to take. If you cool the inside of the computer case to a lower than usual temperature and the problem goes away, this could be a sign of such a problem. There are ways to pin down the culprit. For now, let's see if this is what happens.

    (19) If, after these two tests, the problem has not resurfaced, please, download and run Orthos Stress Prime 2004 burn in (stress) test.

    If your CPU is single core, download the utility HERE.

    If your CPUS is multi-core, download the utility HERE.

    This utility will "stress test" your computers' CPU and system memory.

    (20) Let the test run for a period of hours or until the issue returns.

    (21) Please, post back here w/ the results and/or your observations. We'll proceed from there.

    Thank you
