TypeCPU / Microprocessor
FamilyIntel Mobile Pentium 4-M
Part numberBXM80532GC1700D
RH80532GC029512
Frequency (GHz)1.7
Frequency in LFM mode (GHz)1.2
Bus speed (MHz) ? 400
Package type478-pin FC-PGA
Socket typeSocket 478 (mPGA478B)


New cpu General information:
TypeCPU / Microprocessor
FamilyIntel Celeron
Part numberBX80532RC2600B
RK80532RC064128
Frequency (MHz)2600
Bus speed (MHz) ? 400

Package type478-pin FC-PGA2
Socket typeSocket 478 (mPGA478B)

if more info is needed plz let me know, and ty for all your help in advance

One of the most common reasons why same socket cpu's that are newer generally don't work is due to the bios/motherboard not knowing what it is, doesn't have updated bios information to recognize it resulting in a no boot/no post senario.

So the first thing you'll want to do is.. is stick the old one back in, and make sure the laptop is as up to date as possible.

It's sometimes not a bad idea to see if the manufacturers has a cpu support listed on their website for that specific model.

There are plenty of other possible reason for the issue...

You will most likely not be able to run that processor on that laptop. Most times laptops are built (in particular the older ones) around a "family" of processors while desktops, the motherboard specifically, can support a wider range of processors within a socket series. In this instance, more than likely that laptop will support any of the Intel Pentium 4 M socket 478 mobile series of chips ONLY, which run from 1.4Ghz to 2.6Ghz, and nothing else.

Take a look at THIS page for a full rundown of Intel Pentium 4 M processors. If you want to try upgrading I would stick with the processors on that list.

Edit: I read up on that laptop, and Toshiba noted that they sold it with processors in the 1.4Ghz to 2.0Ghz range. The reason they stopped at that number could be because they consider this to be the "thermal limit" of the laptop, and anything above that speed would generate too much heat, or that the higher CPUs require 5watts more to run, and is pushing the limit of the power supply. Just something to consider when looking for a replacement.
