What price is a motherboard for a Toshiba A70 Laptop??

Hi Barb,

On the Toshiba A70 you should try holding down the fn key at lower left and pressing the F5 key which is the video transfer keyboard command for pretty much every Toshiba laptop. Otherwise, their little pictograms on the F keys almost always have a tiny representation of a laptop next to a monitor.

Hope this is helpful.

There is no way to "boost" the fans. I'm assuming the fan runs.
Buy a laptop cooler from a local store. They come with USB fans that will assist with cooling. Also, never use a laptop on anything but a hard surface, never on a blanket or on your lap.

The noise is most likely an extemely dirty cooling fan. To find out for sure that it's your fan and not your hard drive, take your hard drive out and then turn your computer on. If the noise is still there it's most likely your cooling fan, if not then it's your hard drive. If you don't know how to take your hard drive out or open your computer up to clean it you'll need to take it to someone who can.
Next, you can get a laptop cooler from most office or computer supply stores or any of the online computer parts sites. They range in price from around $10 to over $50. I recommend looking at the descriptions and online ratings, then picking one that best fits your needs rather than going on price alone.

you can try the memory try one stick at a time. also try the laptop with as little components as possible.

remove the dvd drive, hard drive and wifi card and see if it will boot.

then put each one back in at a time and try it to find the culprit

There is a switch on the side of your laptop with enables and disables the wireless card in your laptop. Make sure it is on and lit.

hi there,

you can follow this instruction and try to your laptop to resolved the problem.

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with Toshiba Satellite M35X and Toshiba Satellite A70/A75 notebooks. If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it’s still under warranty, it would be fixed at no charge to you.
Problem symptoms:

1. Laptop randomly shuts down without any warning.
2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
3. The battery will not get charged.
4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. Toshiba Satellite M35X and Toshiba Satellite A70/A75 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system board with a magnifying glass. In most cases you get the power problem because of a bad connection between the DC jack and the system board, you’ll see a crack between the DC jack connector and the system board.
Here is an example of Toshiba Satellite M35X power jack. The crack occurs between the DC jack pin and the system board.
In some cases the connection is good, but the DC jack is bad itself. You can find a new DC jack for Toshiba Satellite M35X and Toshiba Satellite A70/A75 laptops here. Search for DC jack M35X or DC jack A75.
How to resolder laptop power jack yourself.
UPDATE:
Sometimes, after you replace the jack, you can see that the system board doesn’t get power at all. The battery will not charge and the power LED will not light when you plug in the AC adapter. So, here’s a possible explanation.
When a connection between the positive pin and the motherboard breaks (cracks), the power jack gets loose. You can feel it when you plug in the adapter plug. A loose power jack can damage the trace inside the hole in the system board. Take a look at the picture.
As you see, the positive pin goes through the hole in the system board and you solder it on the top side. Right? What if the trace between the top side and the bottom side is broken somewhere inside the hole? I’ve seen it before a few times. In this case everything looks nice and clean on the top side. When you plug in the AC adapter, you get normal voltage readings between “+” and “-“ pins on the top side, but the power DOESN’T go to the motherboard at all, because there is no connection between the top and bottom sides. Test with a multimeter if there is a connection between the top and the bottom.
If the trace inside the hole is broken you still can fix it. You can run a wire to connect the top and the bottom sides. Be careful not to short something on the board.
Update:
Here’s another solution to fix the power jack problem, it shows how to relocate the power jack outside the laptop base. Check it out here: Toshiba Satellite A75 failed power jack workaround.
When you repair a loose power jack, it’s a good idea to check the jack on both sides of the motherboard. When you remove the top cover from a Toshiba Satellite A70/A75 laptop you can see only points where the jack is soldered to the motherboard as it shown on the second picture in this post, but you cannot see the jack itself as it shown on the first picture.
Removing the motherboard from Satellite A70/A75 laptop is a good idea because the jack itself might has a broken “+” pin, as it shown on the picture below. If the “+” broke off the base, you’ll have to replace the jack.

Well this is one of the few that I know of. Scroll to almost the end of the page where is says Toshiba. Good luck!

Becarefull,
Seems like your laptop is overheating, and it shutsdown as a way to protect the processor.
With a vaccum, **** the dirt that might be trapped in the fan or fans.
This should help.
If not, then you need to open laptop and perform a deep cleaning on the Heatsink, and apply fresh heat release compound on the processor.
