we (daughter & self ) have a hp Compaq CQ62. (not a bad little machine for the money) it came with 2 GB memory and we want to increase this. the THING is, the hardware says CQ62-219WM & the software says CQ62-217ca. the software tells us we are running windows 7 (64-bit), but also says we have 32-bit color running on the screen. this is a little confusing for a newbie. the product number is WQ778UA#ABA. 2.2 GHz Intel celeron 900 CPU, systemboard 1484  77.38, system bios F.26, mobile Intel 4 series express chipset family, Intel GRAPHICS media accelerator 4500m video memory, if this is DDR22 memory, (very expensive for us) can we USE DDR23 (less costly). any help would be greatly appreciated.
Travel to Crucial.com and run the online scanner...it will tell you exactly what type and how much RAM that PC will take...
I don't believe you can use the 2nd type you mentioned.

As it is a Celeron CPU i wouldn't spend too much on the upgrade.thanks for the info. is the cpu upgradable?
Depends on what MBoard it is...what is the problem with the intel celeron 900 2.19 ghz. CPU ? & isn't the motherboard the " system board - 1484 77.38 " ?  & just what is the 77.38 part of this number ? This is a laptop, I believe.

This is only if you can ensure that your laptop CPU's socket is identical to the one you are planning to replace it with. For example, the Core 2 Duo Mobile (Penryn) series require a Socket P Micro-FCPGA (mPGA479) laptop motherboard to function properly. I have a friend who UPGRADED his Toshiba Satellite Pro U500-EZ1321?(forgot the exact model) with the Core 2 Duo T6570 to a T9400. However, the T9400 already costs over $300-if your laptop is already decrepit, I would really go buy a new one.


Laptop motherboards cannot be replaced (with mobos from other laptops) because they won't physically fit in.not interested in swapping motherboards/ I've come across a couple of not so excellent reviews of the intell celeron cpu's. is it a bad design or a reliability issue. was intending to put a 4 GB mem. (1x4) in this laptop. it now has 2x1 1GB mem. Celerons were a budget CPU made by iNtel...if you already have 2G of RAM the performance increase of 4G won't be that much as the CPU is the weak link...
Better to put that cash towards a new PC.thank you, wanted a 17'' desktop replacement anyway.
