Acer L3600 Bios flash worries.

  Epirb406 19:13 03 Dec 2008

Hi All,

I have, as some of you may have noticed been trying to upgrade the RAM on my media PC.

I am sure sure that the selected RAM should work, my manual says it should and my vendor says it should, but it doesn't. No post, no boot, no beeps no nothing!

It has been suggested that flashing the bios is the way ahead and I can see the sense in that .

However, I can find no step by step instructions from Acer on this, only dire warnings about a lack of warranty support if it goes wrong.

I have also found a good number of forums where people have bricked similar units flashing the bios.

I am nervous, can I upgrade to RO1-BO without killing my machine? if so, how!!?!?!?

Anyone come across any useful info, support for this fantastic little machine seems a little thin on the ground.

Thanks all, Epirb.

Then i would say with respect the Ram your uing is not correct otherwise your computer would work and doing a Bios flash will not change this and if your not shure what your doing in this area leave alone.
If your not earthed you could have killed the memory with a stactic charge.

Hi, perhaps I should have mentioned hat I have been building systems for ten years or so and do know my way around a box of bits.

I have not fried the RAM and it should work.

Brgds, Epirb.

Below is a copy of the email I saent to Acer Support but have had no response. Thanks for reading! They have not replied in two days. It was entitled L3600 RAM upgrade.


I want to upgrade my ram to 2GB.

I Purchased 2 x 1GB DDR2 PC2-5300 SODIMM.

I installed and got no beeps, no post and no boot, I tried:

Ram A in Slot 1 and Ram B in slot 2.
Ram B in Slot 1 and Ram A in slot 2.
Ram A in Slot 1 and nothing in slot 2.
Ram A in slot 2 and nothing in slot 1.
Ram B in slot 1 and nothing in slot 2.
Ram B in slot 2 and nothing in slot 1.

I then had the vendor replace my RAM and tried the same process all over again, still no beeps, post or boot.

It is now being suggested that flashing the bios will allow this to work.

I can download the BIOS ver. RO1-BO from your website but I do not know if that will help.I am happy to do this but would need step by step advice.

Please advise the soonest!

your new ram high or low density ram? High density rarely works.

can you post the detailed code numbers on the stick of ram?

The 128 -64a in theRM12864AC667 refers to high density chips. It might be worth checking if the old ram is also high density, that may be the problem. See if your supplier will send low density ram.

Bye the bye. Did you reset the bios after you installed the new ram. sometimes reseting the cmos does the trick ;-)

Is 'the fantastic little machine' happy with the original memory or have you ditched it? The original memory that is.

  Epirb406 16:34 06 Dec 2008

Yes, it does rum on the original RAM but rather slowly!

The small print from the original RAM:

No I didn't try resetting the bios.

Cheers for thoughts so far, All the best,
