Pushing Laptop past RAM maximum?

You got lucky the first time. The cpu/ motherboard is engineered for only two and overdrive causes system overload. Simply cannot process. Maybe if you back off you didn't shoot yer cpu. Ram pins shouldn't even match. If it fit, the circuit didn't match.

What operating system are you running?

If you take out the second RAM stick does it work again?

- if it does then try using the other stick of RAM and see if it still works

- - if it doesn't then you RAM stick is dead

- - if it does then your motherboard cannot handle all of the ram you are placing in it

- if it doesn't then you probably accidentally disconnected a wire in your laptop

When you say "the HDD doesn't boot at all" do you mean you get a black screen when you try booting up?

or does it give a startup screen then black?

To answer your question, if you go over the maximum RAM, the motherboard cannot calculate correctly the amount of ram there is and it does not post (meaning you get a black screen).

also 4gb of RAM is pretty good for a laptop, so I would stick with that.

Computers run a little test before they boot to the OS. They check the RAM, the motherboard and other major components. This is called POST or power on self test. The new RAM is causing the test to fail.

If you don't have windows 64 bit then your laptop won't be able to use more than 3GB or RAM anyways, if sony listed it as 2GB max then I'm almost sure 32 bit is what it would have shipped with.

Not sure why it won't turn on but you probably have a 32 bit OS that can only use 4GB RAM max anyway.

You're limited by your hardware AND software unless you have a 64 bit OS. And if you do your centrino processor is going to be the bottle neck and prevent you from seeing any benefit to more RAM.

Over maxing RAM does not prevent PC from turning on, PC however depends on OS limit on maximum of RAM recognised by the system. It also depends on motherboard support.

In your cases, the limit is 4GB, it is impossible to bump it up to 8GB. If PC doesn't boot up, the RAM you bought is likely incompatible. Try to swap the ram or remove it.

Does it incredibly instruct 3 GB of ram put in interior the BIOS or in homestead windows? it won't reason any authentic matters. extra effective than likey this is purely useing the two gig stick of reminiscence as a a million gig, so your no longer making use of the entire stick.

It could do but it could also be faulty ram or that the set of ram doesn't play well with you motherboard. Best thing would be to find a laptop that should handle that amount of ram and see if it works there and also run memtest86 on that computer with your ram to check for errors.
