I was gifted this ~2010 Toshiba Portégé. Surprisingly small and thin for its age. I was hoping to revive it, but it has only 1GB of memory ootb.
Apparently it can be upgraded up to 5GB with one spare slot that currently sits empty.
I found 2 physically compatible identical 2GB modules but no matter which one I plug in, when I start the computer it just starts the fan on highest setting and nothing else happens.
Before I go into any more detail, I found this info online:
The Toshiba Portege R600 Laptop takes the PC2-6400 DDR2-800 200pin SDRAM SODIMM memory type
My sticks look like this:

Are they compatible to PC2-6400 DDR2-800 200pin SDRAM SODIMM? I honestly can't tell.
I read the manual which says the modules need to be "Toshiba approved" but it does not say which/what Toshiba approves.
Plus this, which I did follow (note the negative):
Do not try to install or remove a memory module under the following conditions.
a. The computer is turned on.
b. The computer was shut down in either Sleep or Hibernation Mode.
c. Wake-up on LAN is enabled.
d. Wake-up on Wireless LAN is enabled.
e. The wireless communication switch is turned on.
And this does not happen:
If you install a memory module that is not compatible with the computer, the Power indicator will flash (on for 0.5 seconds, off for 0.5 seconds) in the following way;
■ If there is an error: repeatedly flashes orange twice, then white or green once
The power indicator ⏻ stays white all the time and does not blink.
TIA
My notes only say "Upgraded RAM 2->4GB (had to reset RTC)". There is a good chance I left it unplugged and RAM-less for quite a while as I tend to multi-task and get distracted. A few minutes should be fine though. Just compared the specs of the R600 v R700 and I've got 2 slots and no on-board so that probably makes a big difference. Sorry can't be more help, but there must be a solution. https://www.productindetail.com/pn/dynabook-toshiba-portege-r600-102 https://www.productindetail.com/pn/xvw-dynabook-toshiba-portege-r700-15v-2
Thanks!
I've about had it with this one. Maybe it will come handy at some point even with just 1G of RAM.
I suppose it could be bad RAM modules, dirty contacts, dodgy slot. Can you boot it with a Memtest USB stick (empty or filled slot)? (If you find yourself in London look me up, this is exactly the sort of thing I'd get obsessed with fixing)
Thanks, but I'm in Finland.
I'll have to fire up another machine for the memtest.
Will report back evtl.
