Toshiba Satellite P105 S6124 Power goes off. Jiggling electrical cord at base of computer gets it back on but when it's moved, it goes off again. Someone looked at it and tried a new cord. Determined that it is motherboard. Help!

well not exactly it's a filter for the heatsink for the CPU and is usually on side towards back or underneath

that can get clogged with dirt, making cpu run hot and slow computer down a bit.

we use a plastic ended vacuum hose on medium to remove that dust and dirt from outside of laptops

memory "ram defect"

Power issues are pretty typical with laptops as most time laptops are moved around alot and are not stationary. Here are a few possibliites that could be the reason for you not having power:

1. A/C cord is could possibly be bad. Attempt to use the cord on another outlet, then try to use the same cord on another similar laptop to see if power is transmitted. If cord is faulty, then purchase another cord.

2. A/C input adapter on laptop is faulty. The A/C input adapter is where you plug your A/C cord into the laptop. This can come from the input coming loose or wiring being loose or disconnected.

a. check to see if the part is loose by touching the part with your finger.
b. if you are not a professional, take the laptop to a certifiied computer repair shop.

3. If you are a professional or are comfortable opening the laptop (do bare in mind you opening the laptop yourself violates any warranty you may have), then look at the A/C input adapter to see if it is loose or if a wire was disconnected from the motherboard.

4. If you are a professional or are comfortable opening the laptop, another option would be to check the circuitry on the motherboard to see if there is a bad transistor or circuit on the motherboard.

I hope this was helpful and thank you for contacting the experts.

there is usually one screw holding the dvd drive in, lay the PC closed, upside down, and lay the replacement drive in line with the old drive, this may tell you the exact location, or where to look (it may be under another removable panel, once the one screw is removed, the drive should slide out, if you eject the drawer, it is easier to remove after you pull out the screw, most have a manual eject (Pinhole in front by eject button) insert a straightened paper clip straight in. let me know if this helps or you need more info

Are these lines on the screen during the whole boot process? If so then the screen cpu and/or the video cpu has gone bad. Connect an external monitor. If the picture is clear, no lines, then the problem is the LCD screen. If the lines appear on the external monitor during the boot process then the mother board will need replacement.

Good Luck

For some models, however -- including those listed above -- booting from the Recovery disc requires pressing the F12 key, rather than the 'C' key. The instructions below are correct for these models.
CAUTION: The Recovery process reformats the computer's hard disk drive, which completely erases its contents -- including all applications, all documents, and all other data stored on the drive. Be sure to back up your documents and other data before following the instructions below.
Follow these steps to erase the current contents of the hard disk drive and to re-install all of the software that was installed on the computer when it was manufactured:
1. With the computer on, insert the first Recovery disc into the optical drive.
2. Shut down the computer (click the Start button, click Shut Down, select Shut Down, click OK).
3. Press the computer's power button to turn the computer on, and then immediately press and hold the F12 key. Release the F12 key when the menu of boot options appears.
4. Use the arrow keys to navigate to the CD/DVD option. Press the Enter key to select it.
The computer will restart, and will boot from the Recovery disc.
5. Follow the instructions on the screen to start the Recovery process.
CAUTION: Once the Recovery process has begun, do not interrupt it.

The computer's hard drive will be formatted, erasing its contents. All of the software that was installed on the computer when it was manufactured will then be re-installed.
6. Once the Recovery process is complete, remove the Recovery disc, and press any key to restart the computer.

Are you getting any beep codes?

This is a known bug on some Toshiba lappies - and one of the reasons I updated my A215 BIOS 4 times in the last few months!

Not sure if this is what happened to you, but...

Issue


The computer models listed above may display a "Password =" prompt when the computer is turned on, even though no power-on password has been set. If this happens, there is no password that will satisfy the password request. If the computer is turned off and back on again, it is very likely that the same password prompt will appear. The computer will be unusable until this problem is fixed.

If the problem has not happened yet, you can prevent it from happening in the future by upgrading the BIOS to the newest version.

The occurrence of this problem on any particular computer is unpredictable -- it may never happen, but it could happen any time that the computer is turned on. If this problem does occur, it will be necessary to send the computer to a Toshiba Authorized Service Provider, who will fix the problem at no charge to you.



Resolution


If this problem has not yet occurred on your computer, then click the following link to download and install BIOS version 1.40. This BIOS displays a power-on password prompt only when a power-on password has actually been set via the BIOS Setup program.

You may also browse for a newer version of the computer's BIOS at pcsupport.toshiba.com.

For more help, see Support Bulletin 98081213 Obtaining downloads and support docs from the Toshiba Support website.

If the problem has already occurred on your computer, then please make arrangements with a Toshiba Authorized Service Provider to have this problem fixed at no charge. To locate a Toshiba Authorized Service Provider (ASP), please visit Toshiba's Global ASP Locator at http://pcrepair.toshiba.com

BTW, I've heard that this only happens when you boot up on battery power.

Maybe you can confirm this...

go type in the exact brand of tuner into google in quotes and the word driver and download it. If you cant find one check the companies website and search for drivers

Hi Ed;

This is issue has resolution as it has been published on Toshiba's Official Support Website. It seems you need to go to an Authorized Toshiba Center. They have a special tool to re-flash your BIOS and it will resolve the issue. I am adding the original text and link for the solution below

Good Luck
