Intel Core 2 Duo T5750 Merom 2.0 GHz 2MB L2 Cache Socket P 35W Dual-Core T5750 (SLA4D) Mobile Processor

Pros: Did my research and found this processor is compatible on an Acer Aspire 5315 with factory installed Celeron 560 2.13 Ghz, 3 GB of RAM, Windows 8.1 64 bit. Was packaged well and processor had a like new appearance, no bent pins or heat sink grease residue. I am very pleased so far with the nice boost in overall performance ( IE faster boot up, shut down times, faster page load times, much less glitching on video streaming ) Also I've noticed the cpu fan doesn't run constantly and computer stays cool even when mutlitasking. Highly recommended. Easy installation. Just remove panel on the underside that reveals the memory and CPU. Then unscrew the three screws securing the cpu fan, unplug the connector to the fan, then unscrew the spring loaded screws on the CPU heatsink . Turn flat head screw to unlock the cpu in the socket. Clean cpu heatsink with rubbing alcohol . Apply fresh heatsink grease and installation is in reverse order . Very easy process on this notebook and I don't consider myself a computer know it all.

Cons: Honestly no complaints. Easy installation and a nice, very inexpensive upgrade.

Overall Review: Yes, I definitely would recommend this to a friend. There are many informative sources out there that will tell you what processor your pc takes and if this particular one is compatible with your system.

Pros: Works very well. No overheating. Had this in for 6 months and no problems.

Cons: In response to some others.....This swap doesn't require a "complete disassembly of the laptop". On the Lenovo just pull the battery, Thermal mod cover, Fan, and the thermal mod. It would be better to have some experience replacing CPU's.

Pros: Good price at $27. Good condition recert. The chip was clean. No old thermal paste. No scratches. No bent pins. It seems to work flawlessly. Upgrading to this chip also increased RAM performance. The install was pretty simple, but that will just depend on what laptop you're installing it in.

Cons: None that I could tell.

Overall Review: I got this to upgrade a friend's old Sony Vaio laptop that originally had a Pentium Dual Core 1.6Ghz. Everything runs a bit smoother on Windows 7 now, and I believe this CPU uses less power, so it should run cooler. WEI went from 4.5 to 5.1 for the CPU, and the RAM score also went up to 5.1, although I don't remember what it was originally, but I know it was lower. This chip must have a better memory controller than the Pentium Dual Core. All-in-all, it's a good, cheap upgrade to keep a dated laptop ticking for a while longer.

Pros: Excellent value. Nice upgrade from my original 1.5 GHZ T5250. 25% faster for $27 and free shipping. Under Control Panel, the System icon reports the new CPU, its model (5750) and the new 2GHz speed. You can get tutorials of whats involved on YouTube. Search for Laptop CPU Upgrade. I watched some guy do the upgrade on his bed. It clued me in that the whole laptop needs to come apart. Also showed that the heat sink fins needed cleaning. You will need a smaller jewelers screw driver for that. See more notes below.

Cons: No cons other than its a significant task to accomplish. It requires a high skill level especially if this is your first time inside a laptop - it was for me. It takes care, fine mechanical skills and patience. Make sure you have good quality heat sink compound on hand. Also a drop of oil for the fan and a soft brush for cleaning. A good LED flash light, and a digital camera are handy. You'll want jeweler's Philips head screw drivers. Also fine pointed tweezers. Observe ESD precautions. Always discharge yourself on a grounded item, and touch a ground item on the motherboard before touching connectors or other areas of the board. Some panels snap together or need to be gently pried around the edges. The motherboard may slide out at a 45 degree angle. Watch out for wiring harnesses that are still connected and holding in the mother board. It takes lots of skill and patience to do this task.

Overall Review: The entire laptop needs to come apart. There is a demo on YouTube you should watch first if you've never done this before. Try searching for Laptop CPU Upgrade. Work on a terry cloth towel so small screws don't bounce away. Line your parts (screws) up in rows across the top of the towel in the order they were removed. Mark assemblies and panels with post-ems and put a corresponding post-em in sequence with the screws that were removed. If you have a digital camera, take pictures especially of the inside and wire and harness routing and during disassembly. Take notes if you need to. Small ribbon flex connectors may have a tiny pull-out frame to release the flex cable. Contrary to some YouTube videos, clean the old heat sink compound with a solvent such as lacquer thinner. Take the fan itself apart and clean inside. My blower wheel was held in place only by the magnets and lifted out with some effort. Oil the bearing with a drop on a jewelers screw driver. (I used motor oil)

Pros: Great deal if you have a compatible board. Low power.

Cons: Don't get this if you don't know if it works; there are a lot of pin-compatible sockets (and old BIOS) that won't boot this CPU.

Overall Review: I was also hoping this would work in an older socket-479 Centrino laptop, but no dice. The Socket M Core chips might work. Here's a good reference I found: http://www.cpu-world.com/Sockets/Socket%20479%20%28mPGA479M%29.html

Pros: Bought this for my Lenovo 3000 N200. It replaced a T2230 (1.6Mhz / FSB 532Mhz / L2 Cache 1 MB). The chip is in great condition for a refurb, with no traces of the old thermal paste or scratches. Popped it in and now it's up and running on the first try, no issues so far.

Cons: None so far.

Pros: see other thoughts

Cons: see other thoughts

Overall Review: I am looking for a manufacturer response. I am upgrading an older gateway laptop for use in an auto shop. The current board has a socket 479 Centrino processor and i am wondering if this will fit in that socket.
