    Laptop will not boot

    My niece's Toshiba laptop refuses to boot. Most of the time it does not even show the first boot screen, the one that says "Press F2 for setup, F12 for boot menu". Instead it just has a blank screen and the fan runs very fast. On very rare occasions, it will get to that first boot screen, and one time when it did I booted off the Windows 7 repair cd and ran chkdsk /r from the command line. It found no errors. I also ran the Windows Memory Diagnostic, it found no errors.

    Any ideas what to try next?

    Thanks

    How old is the laptop? This sounds like a hardware failure. If it's still under warranty take it back. If not a visit to a repair shop might be called for. I suppose you could open the access ports in the bottom and ensure that the HD and RAM (these are what I can easily get to in my laptops) are properly seated.

    Yes I agree that it seems time for the manufacturer warranty service. But I figured I'd check here in case I was overlooking something. I did re-seat the RAM already, did not bother with the hard drive since it seems unlikely it would affect the boot screen appearing.

    Hello....You could also make sure that the "Power Supply" connections are all mounted securely ....as well as all the rest ...It's worth a shot. Regards Fred
    PS:It also sounds like the fan feed back to the PC (Temperature signal From CPU) might be running "open loop" so the (Fan) is on full.

    With the fans running at full spped, it sounds like an overheating problem. Do you leave the laptop plugged in all the time? It should be disconnected from power when not in use use as the battery can be overcharged and heat up. Also, get a can of compressed air and blow out all the cooling vents.

    What connections do you refer to? This is a laptop, so are you referring to the DC power connector?

    Jerry, the laptop is cold, been off for days, and the fan runs. Not a real heat issue, possibly open loop as Fred suggests, or just an oddball manifestation due to the state it is locked in.

    Vincenzo, if it's still under warranty then take it back. This really sounds like a warranty issue. Whether it's a connection issue or a PS issue or MB or whatever, these should all be covered under warranty. Laptops are not nearly as easy to disassemble and repair as a desktop and a little slip could void the aforementioned warranty.

    Vincenzo,
    Hello.... Yes anything that has a connector ...Could be loose ( have had that happen to my desktop) or is not making proper contact...you could just remove and re-seat everything that could possibly be causing the problem. Once had a loose motherboard , caused all sorts of problems...Anyway this would be an "easy" first try .. and if not we can then move forward to the more complex. Best to start with the simple things first. Regards Fred

    No boot, not even a BIOS POST. Good clue there. The single good boot to run chkdsk indicates to me the drive is OK. I would suspect failing motherboard or the death of this machine. You haven't indicated the age of this machine, but if it is new enough you may be able to get a replacement board, BUT IMHO you will need the best of luck as IME the majority of laptop boards are only available for the first year of life. As others have said, take this to professional and abide by the verdict.

    I've told her to contact Toshiba for warranty support. Thanks to all for the help.

    Unfortunately RR, if the PC will not boot, or even post I believe the Event Viewer would be unavailable to look at. It sounds as though eevery once in a great while the PC will try to boot, so this does indeed sound like a substantial hardware failure.

    Sometimes laptops need to be cleaned with a can of air. Years ago my old Dell laptop suddenly slowed to a crawl and the fan ran constantly. Fortunately, the cooling vents were just underneath the battery - dust had accumulated so thick on the vents that at first I thought it was a piece of felt! Removing the accumulated dust and blowing out some of the vents with a can of air fixed it right up. What you need to look for is the heat exhaust vents for the laptop and then look at what, if any, panels there are near the vent. Open the panel(s) and blow air through there. You are trying to blow the accumulated dust out of the vent (don't blow the dust into the laptop!).

    Regarding blowing dust out of fan vents - I like to play it safe and insert a tiny screwdriver or a toothpick through the vent in such a manner as to keep the fan from turning. Otherwise the compressed air stream can cause the fan to spin at a higher speed than it is designed for, and the bearings can be damaged.
