Slow Laptop

rsvtoddy

I upgraded the RAM to 4gb and installed a 120gb SSD on my Dell 1540 laptop and installed windows 10 64bit. It runs really quickly now! Total outlay about £45 so well worth the upgrade and it also runs a lot cooler now.

I try and install a 64-bit OS on a 64-bit processor. even with only 3 GB RAM (though 2 GB PC2-6400 can be had for not a lot); there's more to it than just the amount of addressable memory installed.

The Dell 1645 can go slow if the battery is on its way out - how is its battery life?

However, the machine is a bit long in the tooth these days and wasn't the fastest when it was new.

The one good thing they do have is that you can upgrade the CPU, but again it's a question as to whether you'd want to do that. (I have one which I upgraded to a Core2Duo P8700, which is a bit faster than a T4400, but only marginally so.)

I'm running a Celeron T1600 along with 4GB of RAM and an SSD. A pleasure to use.

This is because the biggest number that can be represented by a 32 bit binary number is 3221225472

Really? Not 4,294,967,295?

The number you gave is 3x2^30 which is certainly not the biggest denary number that can be represented by a 32 digit binary number.
