From: Sydney on 13 May 2010 03:45 My Toshiba has deffective RAM. memtest86 shows it. I have taken apart the whole machine and did not find RAM separate module. It seems to me that the ram is included in the motherboard. I called the Toshiba maintenance in France (where I am ) and they told me that the memory module is separate and offer to replace it by buying a new one ! I am puzzled. Any advice on this ?

If memory is not in a compartment on the base (a handy location), then it's probably under the keyboard. For sure you have a site that accepts updated modules. Maybe a quick look-see at the manual would help. J

It appears that this laptop "has 256MB or 512MB on the motherboard." You can view the manual at http://209.167.114.38/support/Download/files_Downloads/PSA60C/SA60EXUM.PDF If your faulty RAM is on the MB, you are going to have a serious problem overcoming it.

The manual says memory exists in two places. Memory is soldered to the motherboard (256MB or 512MB). There is also a memory slot on the bottom of the computer, covered by the "memory module cover" (see page 56). You would start, using the knowledge of how much memory is present in the computer. If memtest86 says there is only 256MB or 512MB, then the computer may not have an SODIMM in the slot. It could be using just the motherboard (soldered down) memory. If the soldered in place memory is bad, you'll need a new motherboard. If the computer reports 1GB of memory, then some of the memory is on the motherboard, and the rest is the SODIMM installed on the bottom of the machine. If that was the case, you could unplug the SODIMM and run memtest86 again, to test the soldered down memory. If memtest86 passes, with the SODIMM unplugged, then you won't need a new motherboard. This is supposed to be a photo of the A60/A65, showing an added memory module. http://www.irisvista.com/tech/laptops/ToshibaA65/disassembly/big/Toshiba_A65_02.jpg The onboard memory is supposed to be in the upper center of the photo, under the gold colored material. I can't tell if that is an actual module, or just chips soldered to the motherboard. http://www.irisvista.com/tech/laptops/ToshibaA65/disassembly/big/Toshiba_A65_17.jpg http://www.insidemylaptop.com/images/satellite-a60-a65-motherboard.jpg Paul

I have a theoretical question for you: Do you think the MB would work if the on board RAM were disabled and additional RAM were installed into the RAM slot? Most MB's adjust the RAM when polled upon start up. Supposed (and most people would never attempt to do this) the on board RAM were disabled by opening the CAS and RAS lead or even the power lead for the IC? Would the first RAM seen then be that installed in the slot? Just curious. > > This is supposed to be a photo of the A60/A65, showing an added > memory module. > > http://www.irisvista.com/tech/laptops/ToshibaA65/disassembly/big/Toshiba_A65_02.jpg > > > The onboard memory is supposed to be in the upper center of the > photo, under the gold colored material.
