It may dependon what make and model of laptop you have. Isn't there anything about it in the manual. If you have no manual then there will be one on the internet on the maker's site. Laptop memory is very often not compatible. When you say the same size, do you mean physically or the amount of memory. The memory size combinations that can be used are often very specific and non-permitted combinations tend to be ignored by the motherboard or else it may refuse to boot up at all.

Thaks guys. New notebad details are here:

My new comp only has 256. Should I buy 2 x 512 as there are only two slots and through the exisitng 256 in the bin?

Thanks.

also any ideas where I should buy it?

Kayak I know you have a shop, do u sell this type?

Buying from Crucial is probably a good solution, they are reliable and fairly cheap. You can get cheaper on eBay but it won't be that much cheaper and the potential for confusing similar sounding memory types is there. Yes if you're into heavy use, multiple windows etc. go for 2 x 512Mb but you could also just add 512Mb and see how you get on.

Don't have a shop Mr E, just sell my own bits of junk on eBay from time to time.

Some motherboards don't allow 256Mb and 512Mb together and some expect the biggest on in slot one. Compaq and ALR have always been odd because they used to design and make their own motherboards which were different and consequently the memory was often different.

Your user guide doesn't have any details of combinations.

It does say to remove the battery pack before changing memory modules though.

Placed the order and they dont have the stock for 2 weeks!!! Requested a refund. Anywhere else that offers a very fast service?

Thanks.

Whats your ebay username Kayak? You did tell me before :-)

Thanks Mega, done.

No I didn't Mr E :-)

You did, about 3 years ago now I think.

Well I don't remember :-)

are you going to give it to me again, delete after 5 if you want (what you did last time).

Here's a very informative 'Internet' site to cast your eye over and then Bookmark:-

can you tell me what asp.net is please and do I need it on my pc. It is in my user accounts and can I delete it as I didn`t put it there

Snip, I wouldn't worry, Its something that would have installed itself as a part of the Windows update process.

thank you robber

My D Link wireless router is playing up - connecting and disconnecting randomly. Several years old so I'm junking it. Replacements seem to vary in price a lot. Any advice on my choice of replacement?

Hi. Dont jknow if anybody can advise...I have installed newswatch desktop alert, but it does not appear to work. Installed the relevant microsoft framework, and then newswatch software. No pop ups, and Iam expecting an RNS!!! TIA

vistauk, is the icon in the system tray? Right click and Refresh stocklist (the copy held by the alert software needs to be refreshed from the newswatch list). If that doesn't work, insert AVZ and ULT which have had announcements today.
