Hi Blevnthyself,

First make sure the ram is fully seated. I know the Toshiba requires a lot of pressure to get the ram to seat, properly. Also, try using just the new ram, to boot. If it fails to boot, the ram is either bad, the ram stick is not compatible, or you have reached your ram limit!

Good Luck!

Acer Aspire M3400 Desktop PC. Memory Upgrade Issue

please check the memory timing settings. if your mixing up ram they may not have the same memory timings and require you to go either higher or to the supported settings that either memory can use. for example if corsair runs at 8-8-8-14 and kingston runs at 10-10-10-16 then you will need to bump the settings to 10-10-10-16 since the computer is trying to set the timings for kingston to 8-8-8-14 which it does not support.

1-3-3-1 beep at boot on toshiba satellite

If the Toshiba satellite uses the Phoenix BIOS, then the 1-3-3-1 beep code indicates a memory problem. The specific problem the BIOS saw on the self-test is 28 Autosize DRAM.

It could be a problem with the CMOS battery. You can try replacing this coin battery. You can also try resetting the CMOS. For some computers, you can do this by removing the battery for 20-30 minutes. Other computers will have a CMOS jumper that you can use to reset the machine. I'd need the model number to check the CMOS reset.

More likely one or more of your RAM is incompatible or damaged or the motherboard RAM slots are damaged. If you have two memory sticks, then if they aren't the same speed or type, this error can occur. Remove the RAM and test one stick at a time. If you recently added memory or otherwise upgraded your RAM, test the old memory and the new separately.

Sometimes, you can accidently get the wrong memory. Some computers can only support RAM with memory modules on one side of the memory stick. Newer memory often has memory modules on both sides. (This applies only if you recently upgraded the memory. You should use a memory configuration tool to check the supported memory for your machine. Each memory manufacturer has one for their memory.)

If this error occurs with the original memory or each memory stick separately, you will need to test the memory in another computer or get new memory to test in your Toshiba. That will determine if the memory was bad or if the motherboard is damaged.

If you add a comment with your computer's model number and the details of your memory for the system, I may be able to provide more specific suggestions.

I hope this helps.

My Toshiba Satellite A15-S129 is very slow How can i make this first. Plz help me at

Saying a computer is slow really is not giving out enough info. The A15's came with 256MB of memory, and runs XP Home - which was barely adequate. So that'd be the first area I'd address: most computers run slow 'cause they ain't got enough memory, and memory is cheap, so it's a crime not to give it an upgrade. If you indeed have 256MB of installed memory, then you should add a 512MB module (it uses laptop DDR PC2100 or PC2700 memory) and that ought to do it.

Hello, Can I install a 512MB DDR DIMM, N mem stick taken out of my Dell Desktop into a Toshiba Satellite A15, S129 laptop? Thanks, RD

You can try, without fear of having your laptop "blow-up".

Turn your laptop off.

Remove the battery.

Physically, does the RAM fit into the RAM slot? If not, the answer is 'no' -- most "desktop" RAM is much bigger than most "notebook" RAM.

If it fits, connect the AC power, and turn the computer on.
If it beeps wildly, or does not beep at all, the RAM is incompatible.
Disconnect the AC power.

Remove the RAM.

Re-insert the "old" RAM.

Re-insert the battery.

Reconnect the AC power.

Do a Google-search for "RAM upgrade Satellite A15" to find sellers that sell compatible RAM.

Hello, I have a Satellite A15 @129 w/756 MB RAM. I'd like to upgrade but don't know the maximum RAM stick each slot will take and don't remember if there are 2 slots or 4. Thanks, RD

The maximum RAM for this laptop can up to 1 GB DDR1 266MHz RAM and 2 memory slot available, so since u have already 756 MB RAM in your laptop, that mean 1 of your RAM stick is 512MB and another 1 is 256MB, so if u need to upgrade, u have to replace the 256MB with 512MB to make it 1GB maximum.
