Well it does.
And it doesn't refuse to work either or give any warning beeps which is why I posted the warning.
I only spotted it by accident when looking at a forum and they had some screen shots of CPU-Z up and it had memory voltage 1.35 and when I looked it was 1.5v on the laptop for one bank.
Then doing a search turned up on a gaming forum the fact that running 1.5v DDram causes some over heating in the gubbins, damaged to the CPU IMC due to a different potential difference and increased power drain from the battery. And over time breaks things giving exactly the same problems as we were experiencing. It works fine for months then starts crashing. If you use intensive memory applications it speeds up the process.
Mind you if you have an Acer you will just think its the normal aging process which is occurring.
