Toshiba Satellite Boot Problem

Posted on 2011-10-10
Last Modified: 2012-05-12
Hi Ya! I've got a Satellite L655-S5072 Model # PSK2CU-01E001 SN 7A056176W that will not boot past the Toshiba Splash. It will not boot to the BIOS, Advanced Start Up or Safe Mode (F2 F12 F8). It will not Boot to the Recovery Console(0 key) or boot from a CD. I tried connecting the HDD externaly to another computer and it wasn't recognized. The laptop is only a year old and the warranty expired Sept 1...rats! After the restart loops about 10 times a black screen comes up there is some text about the PCI express card. Has the HDD or MB failed?.....Thanks,  Don

    seems like parts removal troubleshooting is on its way. :)

    Do you know how remove parts?

    Remove the battery and hold the power button for 1 minute...this will drain flea power...connect the laptop battery back and then switch on the computer.

    Hmm, it sounds like it could be multiple hardware problems. I had a tedency towards the system may be over heating, causing the system not too post. Often the laptop is overheating the computer will shutdown to prevent the cpu from burning out. But when you mentioned that your hard drive is not been detected when connected externally to another computer it sounds like a bad hard drive. Since the drive is not detected externally it may be that the hard drive was not detected internally in the laptop and the computer was posting to the next boot device which it was not able to find.
    What I would do is to remove the battery, and one stick of memory and if you have a divice plugged into the pci express card slot, remove it. Then plug in the power supply only. See if it will boot any further. If it says not operating system detected then you know there is a problem with the hard drive. Try booting without the hard drive, and maybe even remove your optical drive (there is usually only one screw that holds the optical drive in place and it should pop out). If it can boot to the bios after the drives are removed then you can shut it down and try booting by adding the components back one at a time, until you can find out which device is causing problems.

    To check if it is over heating, observe the fan when it is first turned on, are the fans running at full speed all the time? If so then you may need a can of compressed air to blow out the vents as dust may have accumulated, causing the system to over heat. If blowing the vents does not help you may need to disassemble the system to get at the dust.
    Sometime lint (similar to that you get in your clothes drier) accumulates between the fan and heat sink preventing it from cooling.

    Note as ded9 says to drain the flea power may help resolve the issue, but not only would you need to remove the battery but remove the power adapter from the laptop as well. So that there is no power going to the system. Then hold the power button for 30 seconds to a minute. Then you can either try powering up the system with the battery or the ac adapter.

    >>  I tried connecting the HDD externaly to another computer and it wasn't recognized  <<   did you try to power it without the disk drive?  it may just be blocking the mobo
    looks like a bad drive

    here my laptop troubleshooting guide :
    -remove all external devices
    - if no display - test with an external monitor
    - test if it runs from battery alone, or from AC alone
    - test also with a known good battery !
    - remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
    - disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
    - boot -->any display ?
    - if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick
    -if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
    or test it, it should read 3 V
    *** you can test the disk on another pc, if you like !

    for troubleshooting the display (LCD) problems : to me

    Thanks all....the HDD is a gonner. I could get to the BIOS and boot from cd WITHOUT the HDD installed. New drive is on the table and recovery media has been ordered. The owner (my sister) didnt back up any documents or burn recovery media...suprise suprise!.......Don
