I have a Lenovo Z575 Laptop with a AMD A6 3420M APU proscessor (if you dont know what a APU is, its the same as a CPU but it has intergrated graphics), I was wandering whether I can upgrade it to a AMD A10 5750M, both APU's have the same socket type and the same thermal design power of 35 watts which means heat wont be a problem.

all answers are appreciated. :)

Those two might share the same socket type but, laptops use BGA type sockets which mean that CPUs are soldered to the motherboard.

So, it might not be possible to upgrade. But to be on the safe side, contact Lenovo about that.

As far as i know most CPUs are soldered into their sockets on laptops unless you have a high end laptop. But like Varun said you might be better off contacting Lenovo. i would just buy a new laptop tbh. It isn't as easy as upgrading something from a PC :)

If you do try to unsolder your cpu, you will end up with a useless piece of junk that used to be a laptop. So, contact Lenovo about upgrading your CPU.

If upgrade is not feasable, nothing can be done. You just have to buy a new machine that fits your bill.

sounds about right, its a bit unfair really i thinks laptops should become more upgradeable desktops.

Lenovo's Hardware Maintenance Manual for this model indicates that the CPU is removable and replaceable. It's definitely not easy, since it requires removal of 11 other laptop pieces to access the removable CPU. I've never done it myself but I'm posting here because I'm considering something similar myself, since I think the laptop is too slow.

1130 CPU
For access, remove these FRUs in order:
• “1010 Battery pack” on page 34
• “1020 Dummy card” on page 35
• “1030 Hard disk drive(HDD)/Memory/Mini PCI Express Card slot compartment cover” on page 36
• “1040 Hard disk drive” on page 37
• “1050 Optical drive” on page 39
• “1060 DIMM” on page 40
• “1070 PCI Express Mini Card for wireless LAN/WAN” on page 41
• “1080 Keyboard” on page 43
• “1090 Keyboard bezel” on page 45
• “1100 System board” on page 52
• “1120 Fan assembly and Heat Sink assembly” on page 58
Attention: CPU is extremely sensitive. When you service the CPU, avoid any kind of rough handling.

Rotate the head of the screw in the direction shown by arrow to release the lock, then remove the CPU in the direction shown by arrow .

Yeah I just ran into this problem for the first time in a long time. I've replaced the CPU's in 100's of laptops to upgrade them. I've replaced AMD's and Intel's multiple times to make an older laptop run much faster. Especially changing single core to dual and sometimes dual to quad. But I just looked at this newer Toshiba C855D-S5950 and it looks like they started soldering in the CPU's and the GPU's or in my case, they are both in the one, an APU which totally sucks. At least before I could take an older single core Toshiba or Dell with integrated graphics and swap out the slow CPU and replace it with one that has another core and a bunch more megahertz speed. After some mods to the cooling system and as long as I kept within the TPW I would always end up with a nice little comp that. Especially when I would double the ram and throw a solid state hard drive in. Now we have a laptop booting up in 10 seconds that's faster than any display model in any of the brick and mortar stores. Clients would pay for an upgrade instead of having to drop a grand on a new laptop. I just got a BGA machine and really don't have much skill with it so I'm not even going to attempt it. I'm sure This Toshiba has BIOS that only that APU works with this motherboard. What a rip man, they should have just left it alone. I don't see what could be cheaper about having a chip BGA soldered into place over a robot or person setting the chip on the board and turning a screw to tighten it. I've repaired over 500 laptops and have yet to open one where the problem was the CPU was "broken" and was the single cause of the laptops failure. That's gonna suck if they start doing this with all the new laptops.
