Maximum PC

i have a laptop with e-350 cpu/gpu, (asus 5253-bz602)

it will be out of warranty soon and i am considering upgradeing the cpu with the faster e-450.

i have looked on google and haven't found any info or anyone who has tried this.

i even looked to just buy the e-450 chip and havent found one, any help would b appreciated.

You can't, the chips are soldered on the board.

Does this apply for the AMD's A series also. Because I was considering the same thing for a quick and dirty upgrade. Its a Toshibia with an A6.

If it's a laptop, probably not. Laptops do have sockets, but I'm not sure since at the same time, companies do solder them on the motherboard. There's also the question of where you're going to get the processor, because I'm not aware of any vendor that stocks mobile parts.

Well the thoughts behind this are. If a the processor is not soldered to the board then it would more than likely be a FM1 socket. In which case a desktop processor would fit. The only change would be power drawn and heat produced. The laptop stays plugged in almost all the time so if the motherboard could support the power drawn then it would not hurt my battery life much. Also if I understand the A series correctly if its not using a core it will shut it down conserving power so the battery life would only drop faster under load. (this is about where my lack of knowledge makes this educated guessing) As for heat. If i remember correctly my laptop is running about 68* C. (I have never opened the case so it is stock paste) I was hoping that with some good thermal paste a desktop procecssor would not produce much more heat. So now you can tell if I am way off on this or not. I tried researching but could find almost no info. But that was several months back when they were almost brand new.

i think i hit a nerve with this topic, are there any sources for mobo-c/gpu upgrades?

or even a u-tube of an opening of this laptop? then i would know if it was possible. i would think that the mobo diff from 35-->45 would be negligible.

You didn't hit a nerve. I'm pretty sure it's not possible, since in the desktop variants you can't buy the motherboard and processor separately because the processor is soldered onto the board.

Also concerning BonesoofTibado's post, you can't use a desktop version the A-Series APUs in a laptop because they carry higher TDP requirements and they mechanically may not fit (laptop parts don't have heat spreaders).

No you didnt hit a nerve. This kind of information is hard to find because so few people do it because you cant always do it.

So what you are saying is it would generate to much heat. The cooler in the laptop wouldnt be able to keep up with it.

Yes. The upper end of the APU's top out at 100W TDP. Aside from gaming laptops, your average 15" laptop can be expected to handle something like 30W-40W TDP, for all parts.

when i said i hit a nerve, i wasn't being literal.

the question im asking is why does the industry make it so difficult to upgrade the gpu/cpu's in laptops

i offen upgrade cpu in my desktops without any difficulty.
btw i found a source of the e-450 outside the usa for about $40, but im still looking for a site that has a few pics of my laptop opened up. people that have actual knowledge, not just opinions.

is this not a site for tech's or just a "marketing" site?

as i said earlier its out of warranty, im an engineer and i want advice that's on a tech level.

Why is the industry making it difficult to upgrade GPU/CPU's in laptops? Well you probably aren't going to get a definitive answer. And us as consumers can only make assumptions based on observations. But let's discuss the problems with laptops, and how they are a different beast than desktops:

• Why aren't there standardized sockets on laptops, or slots, or other things we find on desktop motherboards? I could say, with confidence, it's because they take up clearance and prevent low profiles that the world desires so damn much. It's not much, but for instance, if you were to keep that 3mm or less a socket takes up, ultrabooks would be thicker. This isn't a problem with those 17"+ beasts, but then again, they aren't called "desktop replacement" for nothing.
• There's no real standardization layout for laptops. And there shouldn't be, considering that it would severely limit how OEMs can design their laptops.
• The cooling system in laptops is often an everything-together solution, unlike the individual solution for desktops. Upgrading one or the other means having to work on the entire system. Imagine if you were to change your video card in your desktop, and every time you did that, you have to take out the processor heat sink.
• Speaking of cooling, the system in laptops is often designed to just cool the worst case scenario for the highest-end part in that configuration can handle. And if you want to cool something more powerful, well you have to get a beefier heat sink to do it. We could have different sockets/connectors for different power levels, but that's just a logistical and consumer nightmare. It's bad enough Intel has two consumer desktop sockets instead of one.

The point is, laptops, as small as they are now, cannot really be made with the same modularity as desktops, because modularity takes up space for all those connection interfaces, messes with the cooling, and considering that very few people who own a laptop have no desire to upgrade it aside from RAM (and we can throw in the excuse because there are no upgrade paths that there's no desire to upgrade...), there's no point in making a system that would be overall more expensive that only an insignificant percentage of the consumer base would actually use.

Well, I bid you luck installing that.

k, thanks for your response.

the power differences between the 2 gpu's are not significant. and i certainly dont want to stymie the wonderful laptop designers, but this isnt a $2000 plus ultra thin laptop either,
all im looking for are other like minded techies who want 2 get another yr or 2 out of this laptop with a little modifications and have some fun doing it.

Well then maybe this isn't the place for you, considering upgrading a E series APU requires knowing how to desolder and solder a BGA chip. I guess you could just use a heat gun and some elbow grease.

Even if you were to do the upgrade, it is a waste of time and money. Its effectively the same exact chip...

A complete waste of your time and money. If you ever try to take a modern laptop apart you will see why, they are often designed in a way where you can't access the screws you need too and the bezel and screen are set with glue that will never be right once taken off. You will most likely end up with a broken laptop even if you get it all back together.

I did this with a HP notebook I had and it was def not worth the hassle...

i know it will b a PITA to upgrade the gpu, considering that i have worked on a few laptop in the past, the TDP of 18 Watt is the same so i expect that the power considerations should not b an issue.

btw thanks for the links, esp the AMD E2-1800 link, looks like a better upgrade path
