Changing out memory

have you checked if you have downloaded the correct driver....??because in most cases that happens if you have installed a wrong driver....hope if this works

You can view the user manual here. Click on 'Users Guide' and the the section on adding more memory begins on page 65. It looks like it's located under the keyboard, so you have to carefully pry the piece of just above the keyboard. There's screws underneath that which hold the keyboard in place. Remove these screws and and flip the keyboard onto its face. The memory modules are covered by a plastic sheet.

Hope this helps

No. The A45 series (and the near identical A40 series) have no base memory: at least one of the two RAM sockets underneath the keyboard needs to be populated for it to post.

open the cover at the back and take the HDD out.
remember that if you are not sure consult someone who knows.

I don’t have a diagram for upgrading memory in this particular model, but it’s very easy. You can access both memory slots from the bottom of the laptop if you remove the memory cover. The cover is located in the middle, right beside the fans. All you have to do is remove 2 screws and remove the cover. I believe Satellite P15 memory is expandable to 2GB in both slots (Slot A + Slot B = 2GB) and you can use PC2100 DDR RAM, PC2700 memory should work too (it will run at PC2100 speed).

Check the laptop specifications before you buy new RAM module. I just discovered that different Satellite P15 models use different memory types. For example, according to Toshiba specifications Satellite P15-S409 uses PC2100 DDR memory, but Toshiba Satellite P15-S479 uses PC2700 DDR memory (I think it might be a typo, but not really sure).

On the web, go to Toshiba.com and select your country. Look for support or downloads then choose your computer. You should get to a page that has all the latest downloads for your computer. You may want to download them all as they will be the latest, and install them.

plz check the manufacture website

I have the same problem and I tried everything and finally I realised it was one of the two ram modules installed. I took it out and it didnt turn off anymore.  But then I installed a 1gb ram module from my other laptop and the computer started shutting off whenever I connected the power adapter so I think it might be the wrong memory but taking the bad chip out solved the problem
