upgrade laptop tc4200 to support 64-bit

[Nofar]

I decided to revive my old laptop to fit to my studies as it is a notebook laptop.

so i wanted to upgrade it so i can put on it the office 365 for tablet which only works on windows 10.

before trying to install windows 10 i wanted to upgrade my laptop to 64-bit capability.

my laptop chipset is 915 family, so according to recommendations i bought the Pentium M Processor 780 which was said in several places to support 64-bit, but once i installed a winows 7 64-bit OS it says the my CPU is incompatible with with 64-bit applications, i seareched it up a bit and got a few recommendations:

1. upgreade my bios

2. enabling virtualization on the bios

so regarding that:

1. i upgreaded my bios to what was available on hp drivers site

2. i have no virtualization option on the bios, however i found that on model tc4400 bios update they have an update that adds virtualization to the laptop, but when i tried upgrading to that i got an error of "this system does not contain the necessary wmi..."

also i added more ram but it says "3 ram is installed but only 1.99 is in use" 

i read on the hp side that my laptop supports up to 2 gb ram because of slots availability and max ram size possible, but since that time a 2 gb ram (of the correct compatibillity) came out so i can put 2 cards for 4 ram, but it is still not accepting it. i thougt maybe after i will be able to upgrade my laptop to 64-bit it will solve the problem.

any thoughts regarding this matters?

- ram expanding issue

- 64-bit issue

Hi:

Your notebook will not have a graphics driver for W10, so don't upgrade to W10.

No 64 bit processors are supported the mobile 915 chipset.

The specs for the processor you bought indicate that it is only 32 bit capable.

The max memory supported is 2 GB.

Hi Paul,

thanks for your answer, i understand everything you wrote,

i have just one question:

i understood that the supported memmory is max of 2gb only because of memory  cepabilities of that time,

is it not possible to support more then 2gb whatsoever if i have 2gb in one slot and 2gb in the second slot?

You're very welcome.

The desktop chipset supports 4 GB of memory (4 x 1 GB), but the notebook chipset with two memory slots only supports 2 x 1 GB.

That is why only 2 of the 4 GB is showing up as usable.

I'm actually surprised the notebook boots up with 4 GB of memory in it.

No harm in keeping the 2 x 2 GB of memory in there, but there is nothing you can do to get it to recognize more than it is now.

thank you for the answering my questions, very appreciated

Anytime.

Glad to have been of assistance.

If you like that model series, perhaps the TC-4400 can run W10 x64 if you get one with a T5600 or higher processor.

That model would also support 2 x 2 GB of memory, and the graphics should also be supported.
