Satellite M40x won't start after upgrade CPU test

I have a portable M40x I took the CPU out of it to replace it with another to test the computer started fine then I stopped and took out and put it's original return CPU, and it wouldn't start. Now it primer with any one of all the CPU. When I turn on the power, all I get is a white screen for a few seconds and the laptop is closed down. Both the CPU is good because I since tested on other computers to make sure that this was not the problem.

Anyone has any ideas on what is the cause?

I m not surprised.
As far as I know, Toshiba does not support updates, and it is not advisable to do something like that.
It of one that the replacement of CPU on laptops is not easy and not recommended.
The processors used in laptops are connected to the motherboard using a process called TCP (tape carrier package). It is a method of permanent connection and is used in the interest of miniaturization and heat dissipation.

He was awarded the new heat paste? It s necessary and important if you want to connect again the CPU.

It is perhaps a reason for not starting.
I think more details you will get from the service guy in your country

    My question is "is it posible to do a reset of the bios parametrers" or "reset the CMOS?
    Is it possible to get it working again.

    Hello

    The flashing light means that it has detected a hardware problem on the motherboard!
    Perhaps you have used a wrong CPU and is not compatible.

    Perhaps the BIOS does not support this processor and therefore this flashing error code appears.

    What say you can't update the BIOS! First of all, that's not possible since only focused on the victory of BIOS is available for download. You must run the Windows operating system to update the BIOS.
    Secondly the update of the BIOS won't help you with this problem!

    You must use a CPU that is fully compatible!

  • Tecra A11 - 11N does not start after upgrading CPU

    Hello

    I would like to do an upgrade of the processor for my Tecra A11 i5 - 430 M 11N to a probably much faster i5 processor. I thought that the i5 - 580 M'd, but the laptop does not start when I installed this processor.

    I started the 430M, done some research on the internet and discovered that the 580 M has a very high FSB speed, and that is what probably does not work / not compatible with my machine.

    http://Ark.Intel.com/products/43537/
    http://Ark.Intel.com/products/49653
    http://Ark.Intel.com/products/49652

    and also http://ark.intel.com/

    Now, I went back to the computer store, returned the 580M and got an i5 - 560 M compared to its specifications as I've seen it would not compatible because it has the same speed of the FSB with the 430 M.

    I then later in the day tried to install this cpu as an upgrade, BUT alas!
    It STILL does not START ALSO.
    I was dumfounded left. The processors in the same line of the family are supposed to be compatible between them provided: lithography, FSB and socket type are similar.

    Or what I'm missing here?
    I did upgrades of CPU in many cases for desktop computers and laptops, and this is the first that has left me with no word to say!

    Please offer assistance or advice.

    Hello

    Recommend to check this doc from Toshiba:

    + Can I put th CPU, screen, or motherboard in my Toshiba laptop? +
    http://APS2.toshiba-tro.de/KB0/FAQ35006D000RR01.htm

    Upgrading the CPU is not supported (officially).
    The point is that, even if the chipset would support the new processor, it would be possible that the laptop wouldn't start because of compatibility problems between the BIOS or other components on the motherboard and the new processor.

  • Compaq 6200 PRO MT: Makes the computer does not start after upgrade CPU

    I have the HP Compaq 6200 PRO PC of MT 615114-001 motherboard and processor Intel Celeron CPU (LGA 1155). After I changed the CPU for Intel Core i5 (LGA 1155) computer does not start. He begins a minute (less than one second) and stops again. No beeps. After you have installed the Celeron back everything works fine. i5 CPU is brand new. What can be?

    In my previous post, I explained the reason it has not worked, and listed the CPU that will work.

    HP tests CPU in the laboratory and publishes a list of processors that will work in a notebook.

    Notebook motherboard BIOS has a list of processors that will work. If it is installed, which is not encoded as OK in the BIOS ROM file, then this will not work.

    Processors published (in the maintenance guide & Service for your nttebook series model) are available in models that can be deilvered in State CTO (configured to order).

  • Laptop does not start after upgrading CPU

    Hello

    I have a dv2528ea and I decided to upgrade the processor and the RAM. According to the manual of the T8300 is compatible, so I bought one on eBay (so-called new). When I powered the laptop, the bios screen appeared as usual, but nothing more happens. Among the options available in this screen only works the "ESC" (boot messages I think). I can't access the configuration. The CPU, RAM, HARD drive and DVD drive is correctly detected, the BIOS and video BIOS are "shaded" don't know what it means.

    I know that I didn't break something because after putting the T7100 back in place, the computer worked fine.

    So my question is: is the burned T8300? Do I have a bios problem?

    I've never updated my bios (since 2007) and the CPU is not physically damaged, but this last part can doesn't mean anything...

    Thanks in advance, Pedro.

    Hi, Pedro.

    I hope it will do the trick.  F.0Une is old and I think that's the reason why your processor does not work.

    The problem is that you are under Windows 7.

    You can put Vista on it and flash, or do you know how to make a flash out of the file based BACK?

    I don't know how.

    I'm saying that you are taking a considerable risk if you flash in Windows 7.

  • Dell Dimension 4600 does not start after upgrading CPU

    Hello

    First of all, I tried to send this last night but received a message on my post approval by moderator? Not yet been approved but seen other people have posted with success more recently. Do not know what is happening.

    In any case, put his hand on a 3.4 Ghz HT P4 Northwood 512 Kb 800 Mhz FSB for £10 on Ebay to upgrade my mother enough old Dimension 4600 which has a 2.8 Ghz P4 512 KB 533 FSB inside... However, when I install it the computer does not light and shows just a light amber. The readers and fans still spin but there is no display. The computer works normally when I put the old one back in.

    I think somehow it is a power supply problem as the new processor uses 20w more energy than the old 2.8 Ghz one. Someone at - it ideas? Just trying to figure if I bought a bad CPU, so I can return.

    Thank you

    Andrew,

    It is not a power supply problem, it's incompatible, or a bad processor problem.

    The first models of 4600 will take up to 3.0 GHz and models later, 3.2 GHz to 3.4 GHz, but this does not offer much of a sudden boost on the 3.0 GHz

    Motherboard Dell P/N F4491 will support up to 3.4 Ghz Northwood leaving Prescott

  • Re: Satellite A300 won't start after updating BIOS

    Today I was installing recommended THAT BIOS update 1.70 to 1.90. During installation, the mouse cursor disappeared and has no reaction to the keys on the keyboard. But there was a message DO NOT TURN OFF COMPUTER. So I waited for long (an hour?), but the update progress bar was always in the same place - as my computers are suspended.

    After a long time waiting without any response, I decided to reset the computer. Only way to do pressed turn on button for a few seconds.

    But after that turn it on again there is nothing visible on the screen, only the reaction of the computer is that bright development under tension is turned on and hard drive will blink every two seconds. What should do? Please help me! I have very important data on the hard drive at this moment! Can I reset the BIOS? I tried to yutm on the computer after you press ESC and F2 key, but no effect. I put the CD with the operating system, but no effect.

    Its possible that the BIOS chip is faulty, causing the update to the BIOS to fall down during the writing process.

    If you have tried reinstalling the RAM and removing the power for an hour, it is not great thing else you can do except send it to an ASP for warranty repair.

  • Satellite M100 does not start after upgrading memory

    I recently bought two sticks of DDR2 1 GB 533 Mhz RAM memory.
    I placed both in the slots (the one under the keyboard and one at the rear).

    For some reason any when I try to turn the computer back on to, nothing happens.
    The screen is black and nothing seems to load.

    Help please!

    The case is clear like a Crystal;

    The M100 cannot start because memory modules are not fully consistent or both modules or only a single module is defective.

  • Satellite L300 doesn't start after upgrade memory

    I have a L300 (model PSLB0A - 08H 022 number) which came with 1x2GB ram. All the info I can find suggests that it can accept 4GB.
    I installed a second 2 GB of Geil DDR667 key and the system came with a lack of memory and could not start.

    Then I traded my single stick for a pair of the same, but I get the same result.
    One of the three sticks work in itself, but no combination of two works.

    I ran memtest with the two installed Geils and it resulted in a corrupted display.

    Can anyone help?

    Hello

    I think that the laptop supports only 2 GB of RAM due to the capacity of the Intel mobile chipset.
    You can check you chipset in the L300 PSLB0A - 08H 022 could and then check the properties on the Intel page.

  • Satellite L300 - will not start after the installation of Skype

    My Toshiba Satellite L300 won't start after installing Skype.
    This happened to someone else, and can I do?

    Thank you.

    I think Skype is probably the most used messenger and ideal application for communication.
    It is professionally designed and programmed. As you know in recent years, it has been offered in many different versions and it is always better and better.

    So I think that Skype itself is probably not the problem. I know that a lot of people also use Skype and I've never heard problem described.

    Anyway, what you can try is to remove Skype and try to install it again. Try also push the BONES at that earlier time. Maybe some Microsoft updates are responsible for the stability of the software.
    It's really not easy to say what the problem is here.

  • Satellite M200 does not start after the RAM 4 GB upgrade

    Hello

    I recently updated my RAM just to speed things up a bit as RAM is so cheap these days.
    I have a MEAC M200 T2130 Vista with 1 GB sticks (2 * 512).

    The new sticks are 2 * 2 GB Dane - elec DDR2 pc2-5300, when I put the two and restarted the hard drive light came briefly and then it is just options BIOS of Idol, no POST.

    I tried to use a single stick of 512 MB with two new sticks and they both work in a 2.5 GB configuration just not together that also this only works when the stick of 512 is in internal housing and not vice versa.

    So if someone has had a similar prob or can give me some advice that would be great, I'm not sure if the motherboard can support 4 GB?
    Thank you, Dave.

    Hello

    There are two possibilities why your M200 doesn't not start after upgrading RAM.
    First the RAM installed may be not compatible or could be faulty or the computer laptop doesn't support 4 GB of RAM.

    I put t know what M200 do you have exactly, but you can check the installed chipset and could check on the Intel page if this chipset would support 4 GB of RAM.

    Hello

    My Toshiba Satellite L500D won't start.

    When I start my laptop lights three on the light green left, the two on the left are not green or red. I hear the coolingfan, no beeps at startup. When I start the laptop with a systemdisk is the same, nothing happens.

    I have contact the supportdesk and they said it could be the hard drive, this seems a little strange for me because I can't begin with a systemdisk.

    I hope someone can point me in the right direction

    Unfortunately on this virtual path, it is not easy to say with certainty what can be the problem.
    It will be interesting to know what you did with your computer laptop last days.
    Have you installed some day or anything that may be responsible for the issue described?

    Update the BIOS maybe?
