Hello:
I have a Toshiba Satellite A75-S1253 that runs with a loud fan noise most of the time, occasionally it gets quiet.
When I shop new tsink/fan assemblies online, they all look the same. I have 2 old Toshiba Satellites (A75-S226 amd an A105-S4134 that are just here for parts. Is there any way that I could substitute one of the older ones (A75-S226 OR A105-S4134) heatsink/fan units for the S1253′s? Will the other ones fit and run in the S1253? I’d hate to order a new heatsink/fan for the exact same unit (A75-S1253) if I can use one of the older ones, especially if it will still be loud with a part made for it.
Please help,
Randy Donahue

I have an A70 I picked up free with the broken power plug.The HD was removed, so i bought a new 160GB drive,and picked up 1GB pc2700 ddr1 333 ram. I resoldered the power plug,put in the new drive,but it will not boot with the ram installed.it powers on,but the monitor does not turn on.Without the ram it boots fine,and reinstalled xp no problem.I saw a bios update on the website.Will this fix the ram issuse or is that ram not compatable with this dinosaur?

I have a Toshiba A75-S209, SSN X4345796K. The wireless card internally went kaput – no bars at all directly under the Router. I know the Router works okay, as it is powering the next HP desktop right in the next room. I had the Laptop downstairs, but brought it right up in my den under the Router, and NO bars. Actually, I came back from a 37 day trip and found the computer very slow and no wireless. The battery is okay, as I always plug the computer in to AC power. I’ve tried to find out the cost of the internal wireless card, with no effects – even from Toshiba. Can any one help, other than recommending a PCMPIA plug in?

Louie,

I have a A75-S209.
Turns off after 20 minutes. Computer store says mother board is fried, but after reading the posts here, I am not so sure.

Probably overheating. Try cleaning cooling fans and heatsink with compressed air. Blow air into the fan grill on the bottom of the laptop unill both fans are clean.
Take a look at this article and you’ll see what I’m talking about: http://www.laptoprepair101.com/laptop/2006/01/04/toshiba-laptop-overheating/

Anyhow, I have every screw off the back, but still cannot get the cover off to access the mother board. Is there a picture or diagram somewhere? What am I missing?

There is a link to the disassembly guide. Here it is again: http://www.irisvista.com/tech/laptops/ToshibaA75/satA75_1.htm
The guide has three pages explaining how to access the motherboard.

Try cleaning fans before removing the motherboard.

Jorge,

i need to know haw to enter to the Bios Setup of my Laptop Toshiba A70 SP205 that start to show me an error messege PXE-E61

It’s either Esc, F1 or F2 keys.
Turn on the laptop and try all this keys one by one. One of them will take you to the BIOS.

Chris,

I have a Toshiba A70 with 512MB RAM and I purchased a 1GB stick of Crucial RAM (CT12864X335). After installing the RAM, I went into the BIOS to update, but it would not allow me to change the current memory setting of 384MB. Also when I went into “my computer” to see how much RAM it is recognising, it also states 384MB. How can I get my computer to recognise the added RAM?

Make sure the 1GB memory module is seated correctly. The new memory module should be detected and configured automatically.
Most likely you just didn’t install it correctly.

BTW, the laptop boots up fine and runs like normal. Thanks.

Spike,

Have a toshiba a75 s231. Is it possible to upgrade to a newer duo-core or quad core processor and more ram?

You cannot upgrade the CPU. This model will take only Pentium 4.
But you can upgrade memory. There is one slot on the bottom of the laptop, you can install up to 1GB memory module into that slot.
