Equium A300D will not start.

My Equium A300D does not start. It just displays 'the file is possibly corrupt. The file header checksum does not match the checksum calculated. Why? What can I do? I have only a few months.

Have you installed lately new RAM? Its important to the RAM test before use. Or the standard RAM is possibly defective.

Go to www.memtest.org and run Memtest for a few passes (it is a bootable CD).

The file system may be damaged, try running CHKDSK from the Recovery Console. http://support.Microsoft.com/kb/314058

The HARD drive could be faulty, Hitachi DFT is a good HARD drive tester. Run the test advanced to search for bad sectors.

  • Equium L10 will not start

    Please help - my Equium L10 will not start.

    Power supply is OK. When the power is connected the orange battery light comes on. I press the power button the green power light turns on momentarily (literally a Flash), then both the Green and orange lights out with orange alone returning it on about 2 seconds later.

    Else does nothing - no fan activity, no hard disk, no activity of the screen activity, no other light - you get the picture!

    I tried the following:
    Removed battery and tried to start with AC power not only - no joy
    Removed AC power and I tried booting with battery only - no joy
    Barrette of RAM removed and reinstall - no joy

    Does anyone have ideas before considering a tech? Suggestions (with the exception where to paste!) would be welcome.

    Kind regards

    Hmm .He doesn't sound good. For me, it looks like a motherboard problem. It is maybe something wrong with electronic power to the Board of Directors of s. But not for sure.

    What you can do is to remove the battery and unplug the power adapter for a while.
    Wait about 20 minutes and connect the battery and adapter for the laptop. Then try turning on the laptop computer.
    If this does not help I recommend contact the ASP technician, because I don t think you will be able to know what's exactly wrong.

    So I hope that the technician can find the fault quickly and can solve this problem.

    Good luck

  • Equium A60 will not start

    Hi, I am despartely needing help with my A60 equium that won't start. When you turn the button lights up, fan and starting, but then in a few seconds the cutting power. I tried different sources of energy, also just by using ac power and battery just all produce the same results. I had installed a memory chip a few months back and thought it might be that, but when I took it off the laptop has always been the problem.

    Is there that anyone may be able to help me with this problem? Thank you

    Hi Michael,

    The first thing that happens when your, press on the power button on your laptop, it's that the CMOS chip (which contains your BIOS) through a pre-deignated POST (Power On Self Test) process that verifies the functions of the material of base components after what the BIOS will be charged which will lead in turn to the operating system itself being started.

    If a failure or a problem occurs during POST and then power on the sequence stops (usually after a series of beeps are emitted that are coded to help the diagnostic process. The actual beep codes are specific to the manufacturer of the CMOS/BIOS chip.

    If you receive no all audible sounds, then it is likely that the problem is very early in the POST process and may indicate a problem with your main card or your electronic internal.

    You can try to remove and and reinstall devices such as RAM memory modules, hard drive, optical drive, etc to see if this corrects the situation, but if not then you will need to take the device to authorized, Service partner who has the diagnostic equipment needed to perform accurate control.

    Kind regards

  • Equium L20 will not start properly

    My laptop L20 primer not. A black screen appears "apologize for the inconvenience, but windows did not start successfully.

    Then tells me to highlight a choice of starting up, but when I choose, it moves quickly on a blue screen that I cannot read, then goes back to the same black screen.

    Help! It feels like Groundhog Day.
    Cannot make it work.

    Hi Donna,.

    More simple you take it out of this situation is to reinstall your operating system of the recovey CDs. Unfortunately this won't replace your data (unless you have partioned your hard drive and store your data on a second partition).

    This problem is usually caused by a missing or corrupt system files that prevent Windows from loading. Of course, you can try to recover the situation by using the since the original Microsoft Installation CD Recovery Console if you have one.

    It is also possible that the failure is due to a defective hard drive but it will become apparent when you try to re - install.

    Kind regards

  • Equium A60 will not start - get a beep code

    Hello

    This laptop has problems with ATI (even those included on the recovery disk) display drivers. He created a blue screen on a dll file.

    After reading around, I found that it was recommended to upgrade the bios, after going to the appropriate section of the Web site, I downloaded the flash tool from windows for the laptop bios.

    I ran and it opened, returned to the laptop and the screen is blank, a blue ring around the power button is on, but no display.

    I left it for a period of time see if it would to restart or something, but nothing has happened, it would not be the button turn off so I unplugged the power and removed the battery.

    To again turn on the laptop, it only stays on for about 3 seconds then turns off again.
    I get the beep code: short break, Long, short break, beep, beep beep, then it turns off.
    The caps lock and numlock keys are turned on.
    The DVD drive light blinks.

    But other than that, no display etc.
    Ive tried the battery leaving aside for awhile.

    Anyone have any ideas why flash bios toshiba own this would cause? Also what can I do about it? in any case to recover the bios etc via a recovery mode?

    Thanks in advance.

    Hello

    Well, unfortunately for me it looks like a hardware failure.
    Maybe the motherboard is broken.
    These problems may occur if you use a bad BIOS or the incorrect BIOS update procedure.

    Please check this document FAQ How to upgrade the BIOS:
    IOS http://eu.Computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/FAQ.jsp?z=234&service=eu&from=faq_selection&CFID=B & FID = TRO0000000b07

    Unfortunately if there is something wrong with the hardware you should ask Toshiba service for assistance.

    Some of the fundamental things include the pram/clock battery replacement

    since they may be dead; then with a power failure, sometimes the Mac

    do not restart. Usual power management unit & reset NVRAM/PRAM are

    methods that sometimes also used as a troubleshooting measure.

    A hard reset can sometimes be used, where the power is disconnected

    the logic board and power removed from grill; Then push the Start button / stop.

    (But maybe not. Several PowerMac computers, I had, some people found this helpful)

    You may also remove and reposition cards and other items

    the inside of the case, to be sure they are connected properly. Be sure to not

    In short anything, due to the static load or residual power in the circuits.

    The hour is late here, so I'm not going offline; If all goes well a battery original or novel, etc.

    can help to put it on again. Also sometimes the power supply has some faulty fans,

    circuits or capacitors, so they can be troublesome to repair or replace.

    Good luck in this case!
