Review: NEEDS MORE MEMORY! Otherwise good processor for the price. AND has EMPTY M.2 SLOT!!! - UPDATE: See my comments below as this update relates to the issues I described. I purchased 16GB of CL9 RAM (read: high performance) and this thing is FLYING! It's like night and day. Anyone having performance issues buy more RAM immediately! Super happy that the issue was just a hardware bottleneck w/ the RAM. Also, when I was in there changing the RAM I saw THIS SYSTEM COMES WITH AN M.2 CONNECTOR. In case you don't know, this is what's replacing SATA and PCI Xpress eventually. It's faster than SATA 6GB/s . So instead of worrying about shuffling around drives to get an SSD in there, I can simply by a 500GB M.2 SSD and be all set w/ 500GB SSD and the original 500GB 7200RPM mech drive. Stoked. That M.2 slot just got this system a 4th star. END UPDATE This system should have come with more MEMORY! Huge bottleneck at memory causing hard drive bottleneck as well. This system should not be sold with 4GB. 8GB is MINIMUM! I just ordered 16GB performance memory from Kingston w/ CL of 9 and hoping that will be enough. Pros: PRICE: Great deal for this processor, but your going to need to upgrade the memory for sure, so that kind of sucks. TRIPLE DISPLAY: This system is capable of a triple display using VGA and HDMI at the same time. PROCESSOR: The processor is awesome on this. Rated Top 15 still, and probably the best processor your going to get in any system at this price range. It rarely gets above 20% usage and usually sits at around 5 - 7% so no complaints on the processor at all. THINKPAD: It's a thinkpad, old school tradition, sturdy construction, old school track ball, finger print reader, looks cool, etc... SSD OPTIONS: The hard drive is on a SATA III 6GB/s connection so you can replace it with an SSD and get maximum speed. I also read on forums that people were taking out the optical drive and putting a custom caddy and SSD here. Then you would get to keep your hard drive and have an SSD. You can then put your optical drive in a custom enclosure and use it externally. Not sure if the optical connection is SATA III 6GB/s but I think it is, so I may go with that option if so. Cons: MEMORY: !!!! BUY MORE MEMORY IF YOU BUY THIS SYSTEM!! Mine only came with 4GB. This was enough for my old Toshiba that's 4 years old and has slower memory and is running windows 7 as well. But for some reason this thing can't keep up. Huge memory bottleneck which then starts writing to the page file and jams up the hard drive with a bunch of disk access. The lack of memory included is the reason this did not get 4 stars. WIFI: The wireless adapter in this thing is horrible. I'm constantly getting kicked offline, internet browsing is super slow with many lags and freezes throughout. I did some tests using my 4 year old Toshiba and it works fine while this pile of junk is not even able to connect, or getting super bad lag. TOUCHPAD: The touchpad does not have a button to disable it. Also, there is not way to disable it through software. The only way to disable the touch pad is to uninstall the driver. Then if I am in a situation where I don't have the USB mouse, or the USB ports all stop working, or maybe my mouse breaks and I don't have a spare handy, I have no way to use the mouse if I have uninstalled the drivers for the touchpad. So my only two options are have the stupid mouse doing stuff while I'm typing, or possibly be in a situation where my computer is un-usable. Not too great. Most computers have an option to 'disable touchpad while USB mouse is plugged in'. Apparently Lenovo didn't think this was important. I guess they were too busy marking all their systems up $100 to $200 more than other systems with similar hardware by competitors.
Review: Fine notebook - Fast, competent and free of the cursed Superfish/Adware - Drawn to the i7 (my third i7) and the promise of more sound 2010 engineering than the cheaper "consumer" Lenovo's and all the new super thin notebooks. (I never gave IBM Thinkpads a chance, but was committed to high-end Toshiba notebooks for the last several decades.) Was concerned about Chinese ownership/engineering/manufacture, but mine seems robust (very much so, compared to my flimsy/fragile 2014 HP Envy i7 17") and appears to be competently constructed. Purchased at desertcart marketplace from Adorama (3/13/2015 ~~ low $6xx's), I feared the curse of Superfish (see ZDnet coverage) and prepared myself to remove that dangerous root certificate and the associated adware. I was happy to discover that there was almost no adware. I just had to kill the typical Norton and other pre-installed apps before installing my own. This was the least amount of preloaded junk I've seen in seven years --- the Superfish mess must have scared Lenovo straight! I can't imagine why people complain about the display -- mine is very bright and I run it at about 75% of full bright. Keyboard is very high quality and requires only slight adaptation from a standard keyboard layout. The tilting touchpad required about a half-hour acclimation period before I started to admit that it was also a competent, effective design. Ergonomically, it beats my HP and Toshiba twin-key touchpads and also my wife's Sony Vaio twin-key touchpad. Darn ... I might grow to admire this model. I'm going to give it thirty days of full workload and then report, but my expectations after six days are very high.

## Questions & Answers

**Q: Does this computer come loaded with Windows 7 professional?**
A: It had the option of Windows 8 or 7 professional.

**Q: Does this laptop come with windows 8 upgrade included?**
A: This might help.  We are very happy with the window 7 3 of 3 people found the following review helpfulGood laptop with issuesBy LarryD on August 17, 2014Verified PurchaseI've had this laptop since July so I've gotten used to it. There are some growing pains with this unit that I will detail as well as its strong points.Firstly, it is a fast unit, but will benefit greatly from a SSD drive or at least a hybrid (I swapped in a hybrid and it boots quickly and loads applications fast).The first irritant that I encountered was upgrading from Win 7 to Win 8.1. You'd think it would be a simple, straightforward process but you'd be wrong.For the first half hour or so, you have to be present to insert and remove any of the four Win 8 upgrade DVDs. After that it will install Win8 unattended. After another hour or so you have Win 8.0. But of course, Win 8.0 is no longer supported, so you will want to upgrade immediately to 8.1 So you think you will just go to the Windows Store and run the free upgrade. Well, you'd be wrong again. Before you can upgrade you have to run a Windows Update to get all the security and other critical updates first. Well, there were about 400 of them! Fortunately, that process can run unattended.This process must have run three hours or more, downloading and installing each update. After that you can finally run the 8.1 update from the Store. That will take another hour, at least, while it upgrades and does multiple reboots. From start to finish the entire upgrade took from 11:30 am to 6:30 pm to complete, and I didn't leave it waiting very long between steps.If you look underneath of the laptop you will find a Win 8 Pro sticker, not a Win 7 sticker.So, you might wonder (I did) why we have to do Lenovo's job to make this a Win 8 machine. You might think that Win 7 is an adequate OS and you'd be right. But the touchpad is designed for Win8 and all the good features reside there.Read more 

**Q: I am planning to purchase an SSD to replace the current HDD. Would I still be able to use the same Win 8.1 licence?**
A: Mine came with Win 7 professional installed and with four Win 8 disks included in the package. Win 8.1 will be fine for you, but I'm not sure about the Win 7 license that comes preinstalled.

**Q: Does this have an optical drive**
A: Yes, it has DVD-Writer.Best regards,Amuras

Technically a very good laptop but by todays standards the display just does not pop and lets face it that impacts everything. Compared to the screen quality on my existing 2008 Pavilion DV-7T with discreet graphics it was not what I had expected/desired so I returned it.
