Can anybody tell me in what order to add memory in the 4 slots 2 under KB and 2 under bottom cover. I ordered just 8GB from Lenovo and now what to add. The supplied 8GB seems to be installed. The two slots under the keyboard are 3 and 1. The two slots on the underside of the laptop are 4 and 2. They need to be populated in pairs using matched identical timing memory pieces, in order to run optimally as "dual channel".
If only a single stick is inserted then you get non-optimal "single channel" mode. The slots below the keyboard are harder to get to, since the keyboard must be removed first.
And the two slots are one-over-the-other i. The underside bays are flat and easy to get to. If you don't want to be bothered with the "hard to get to slots", your best advice is to order TWO memory sticks from Lenovo with the machine, and they will then be factory installed in the two under-the-keyboard slots 3 and 1. That leaves the other two easy to access underside slots 2 and 4 for you to add additional memory to at some later date.
The order DOES matter. The "pairs" are important, if you want superior "dual channel" memory operation. Otherwise, if you don't populate the "paired" memory slots with matched pairs of memory sticks, you will get inferior "single channel" memory operation.
The machine will still work, but you won't be operating optimally. So, for best performance you have to use both under-the-keyboard slots 1 and 3or both easy-to-access underside slots 2 and 4.
Or all four. If instead you use one memory stick in each of these two "pairs" e. So if you buy one memory stick from Lenovo, they install it in 3 under the keyboard. If you want to add your own second memory stick you should install it in the second under-the-keyboard slot, 1. Hard to get to because you have to remove the keyboard to install it yourself, but that's where it should go for best results.
Yes, you can in fact install it in either of the easy slots 2 and 4 and the machine will in fact work, but that's not the optimal "paired" location 1 to go along with the single Lenovo stick in 3 under the keyboard, so you'll get "single channel" behavior.
Make it easy on yourself. Buy two sticks from Lenovo, and let them do the hard job of using the under-the-keyboard installs for the two sticks in 1 and 3, and get optimal "dual channel" performance.The Lenovo ThinkPad P50 gives you speedy workstation-class performance and all-day battery life in a portable package. When you want no-compromise performance for CPU- and graphics-intensive tasks like 3D modeling, 4K video editing or running engineering software, you need a mobile workstation.
The 5. However, other inch workstations are much more portable, such as the Apple MacBook Pro 4. The P50's raven-black, rectangular chassis follows Lenovo's classy but staid ThinkPad design language, with splashes of color provided by the bright-red TrackPoint pointing stick and status lights on the lid and deck.
However, a soft-touch surface on the lid -- something you don't see on most other ThinkPads -- makes this laptop more pleasant to grip. I just wish the palm rest had the same comfortable texture.
Lenovo's workstation has the kind of security and manageability features that enterprise IT departments require. The P50 also comes standard with a single-touch fingerprint reader on the deck. The P50 has the kind of best-in-class, snappy keyboard we expect from a ThinkPad. The large, smile-shaped keys provide a deep 1.Una canzone daltri tempi
I felt extremely comfortable taking the 10fastfingers. As always, I found that the little red nub provided extremely accurate navigation around the desktop and allowed me to move windows, highlight text or click icons, without lifting my hands off of the home row.
If you're not a big fan of pointing sticks, you'll appreciate the ThinkPad P50's 3. During my testing, the matte-textured pad responded quickly and accurately to both simple pointer movements and complex multitouch gestures, such as three-finger swipe and pinch to zoom.
I really appreciated its dedicated left, right and middle mouse buttons, which help it avoid the jumpiness we sometimes experience on other units, where you have to press down on the pad to click. The ThinkPad P50's Every part of the Windows 10 user interface and software looked rich and lively, from the bright blue in the Edge browser icon to the deep green of the Xbox app. A desktop wallpaper of a bright, blue sky above orange-brown cliffs really popped. When I played a p trailer for Captain America: Civil War, colors like the red in Iron Man's suit and the slate blue in Steve Rogers' mask appeared very true to life, though not overly saturated.
Fine details like the wrinkles in Robert Downey Jr. The picture remained true, even when I moved 90 degrees to the left and right. According to our colorimeter, the ThinkPad P50's screen can output an impressive percent of the sRGB color gamut, which is even better than the desktop-replacement category average percentthe Dell Precision percentthe HP ZBook Studio G3 percent and the inch MacBook Pro Any screen that can display over percent is excellent.
The ThinkPad P50 comes with an optional color calibrator built into the deck that you can use to improve the display's accuracy. After I fired up the Pantone application and clicked a couple of buttons, the software prompted me to close the lid so the calibrator could do its work.
After a minute or two, the laptop beeped to let me know that the process was complete and that the colors were just a little richer than before. Though it provides strong viewing angles, the P50's display isn't quite as luminous as some competitors', registering nits of brightness on our light meter.
However, the MacBook Prothe Precision and the category average were all brighter. Sitting in a thin bar above the keyboard, the ThinkPad P50's speakers provided tinny but bearable audio that was only loud enough to fill a small room.
When we played both the bass-heavy "Forget Me Nots" and guitar-laden "Smoke on the Water," the vocals, bass and guitar sounded fairly accurate, but the percussion was distractingly tinny. The preloaded Dolby Audio software offers equalizer presets optimized for Movies, Music, Games and Voice, but we prefer the Dynamic setting, which adjusts the output based on the content.
The top surface of the ThinkPad P50 stayed relatively cool throughout our tests. After the laptop streamed video for 15 minutes, the touchpad and keyboard measured 83 and 84 degrees Fahrenheit, respectively. However, the bottom hit degrees, which is quite a bit higher than our degree comfort threshold but won't be a problem unless you try balancing this relatively bulky system on your lap.
The ThinkPad P50 has a generous array of ports; we just wish that most of them weren't on the back, where we had to lower the lid or turn the system to get to them. The left side only has an SD card reader, an optional ExpressCard 34 port and an optional smart-card reader. The laptop's p webcam captured decent images of my face, both under the bright fluorescent lights of our office and in my dark living room.
However, as with most other webcams, there was more than a little pixelation in dark areas. With its 2.First time buying a laptop. The Xeon I'm looking at can manage up to 16 lanes. That's how many lanes the Quadro graphics card will take.
If I understand things, this should be possible. At least "in theory". We don't have a visual diagram of how PCIe lanes are routed to each component.
These are routed through the Quadro and therefore fall under its 16 lanes. Or maybe reach-out to Lenovo's engineers to write up something in this vein. I am about to run some multi-hour long CUDA computations and will find out how good the thermal managment is on the MM.
Adam - Excellent points all-around. We do have technical info out there and can look into compiling a list to sticky at the top of the forum. Details like PCIe lane routing are currently beyond the published info and would likely still end up being asked about in a thread like this.
Perhaps as more questions like this are asked, it might change the level of detail published. No promises though but it's certainly worth considering. Keep us posted on your CUDA project. Post a new thread when you get results and let us know details about your software, system config and the project itself if it's something you can share in public ie: it falls outside NDA if it's for an employer or client.

I found another visual within the User Manual, which is different from the Service Manual. Very frustrating. Unfortunately the FRU part pricing that has been provided is indeed accurate. The pricing provided is not negotiable as per existing agreements set between IBM and Lenovo. Automated price changes may occur as per supply and demand - checking at a later date may yield the results you require.
As this is the case, we must apologize for any and all inconveniences this may cause. Best regards". Yes, and there is no confusion in the matter either, they replied to my e-mail regarding the screen shot to them, and they verified it's I'm sure it may just be a temporary price lock to prevent anyone from buying the parts. So, I can understand it, but I have the good-ol speaker pop issue occuring on my P50, might post about it in another thread.
Sincerely Karen usparts ". But I didn't know it was that expensive. Here is a post from a German forum. Google translate reveals that the people there were told weeks for delivery with a price of Euros. The other part is more of a bracket that wraps around three sides of the drive and snaps into it.
You can see it in the HMM diagram on page 63 if you look closely. It has a tab sticking up on one end that you can grab to lift the drive out of the bay. But the text does not mention the bracket, and yes, there is no part number on any Lenovo parts or FRU list. The bracket is, however, very clear in the Lenovo training video where they show you how to remove and replace it.
First and foremost Lenovo phones are multifunctional, design and low price. But the majority of users are increasingly complaining about various problems in working capacity, which forces owners to seek help from Lenovo service centers. The most common problems of Chinese handset phones are: - lack of strength of the case damage to the screen, scratches or cracks on the case ; - internal problems software malfunctions, lack of network signal ; - poor quality of the connectors not charging, the sound in the headphones is interrupted.
The importance of the microphone Everyone understands that the main purpose of any mobile phone is communication, which must necessarily be two-way.
This function is answered by a microphone, which is built into the device and thanks to it we are able to communicate with each other being at a great distance. In addition, it is thanks to the microphone that the user of the phone acquires the ability to listen to music, watch video with sound, adjust the alarm clock on his own device and so on. In general, it is very difficult to overestimate the importance of the top microphone of Lenovo.
Lenovo microphone replacement may be required in several cases, but the most common types of problems are as follows:. Replace the top microphone Lenovo is quite difficult, so it is not at all desirable to perform such work yourself.
The fact is that trying to repair one part, it is possible that an inexperienced and illiterate person in this case will be able to damage other parts of the phone. It is for this reason that it is best to trust the business professionals who, in the shortest time, and most importantly, qualitatively and safely, make a replacement for the Lenovo microphone. From time to time, mobile phone users complain that they have stopped working properly with a front-facing video camera.
It is worth noting that such a breakdown may occur due to several reasons. The most banal reason for the ineffective operation of the camera is that there simply is not enough free space, and accordingly, you can not use it, since files can not be saved, or rather will not, where to store them. Sometimes you just need to turn off the device, turn it back on and it's likely that the camera will work again.
But, there are situations and more complex, when the cause of the problem lies in the failure of the loop or chip. In such situations, you need to replace the Lenovo camera. As a rule, the replacement of the camera is necessary after the following defects are observed:. It is worth noting that the replacement of the front camera on Lenovo can be done independently, if you follow the correct algorithm of actions, namely:.
Many, probably, are interested in the question about why a cable with Lenovo sensors is needed and what functions are actually performed by such components. If in short, the loop in the phone is needed to play the role of a connecting element between the other parts.
In addition, it is through the loop that electrical signals are transmitted from one part of the phone to another, so it is really difficult to overestimate the importance of such a part. How to replace the sensor yourself In fact, a cable with Lenovo sensors is not as easy to replace as it might seem at first glance, but it's better to entrust this business to professionals. But, if a person decided to do the whole amount of work on his own, then first of all he must prepare a screwdriver with a small thread.
Replacement of the loop with sensors up to Lenovo is carried out in several stages, namely:.Part book komatsu
If the phone starts to discharge too quickly or does not turn on at all, then there is a need to replace its battery. Battery replacement Lenovo is not needed because there was some kind of breakdown, just in time, any part is worn out, since there is nothing eternal. Steps to replace the battery In order to replace the battery on a Chinese phone, the following algorithm of actions should be observed:.
The touch screen helps to perform all functions in Lenovo, creating SMS messages, listening to music, browsing the Internet, without a screen the phone would be useless. So it happens that the display is the most vulnerable part of the phone, because it often often appears small scratches, chipped or damaged.

Phones Lenovo series A, C, K have a fairly wide screen. Therefore, first of all he suffers directly. Replace the glass on the phone Lenovo, you will not be difficult. Lenovo itself is a cheap analog of more expensive phones, but its functionality and characteristics are liked and loved, almost everyone who was, familiar with it.
