Pros: Video card, Display resolution, Display performance
Cons: stiff backstand, high pitched noise
"Had this pc for a month - video quality and performance is great, fast & smooth w/ gaming & watching shows.
The backstand didn't seem to budge past 15 degrees. I was hesitant to push any further as I didn't want to risk breaking it. Finally decided to try again- w/ perseverance and a LOT of force, I was able to pull the stand out further. Poor design IMO.
Otherwise, the one & only annoyance is this high pitched buzz emitting from the PC. I'm certain it's the harddrive but it drives me nuts and literally gives me a headache. At times it can get really loud & I have to sit further back to try and avoid the screeching. It's not enough of a problem to return the whole thing but it's a real nuisance that some might find intolerable."
"I bought the B540P 3D all in one with the Touchscreen, I then upgraded to windows 8. After working out a couple of driver issues I could not be any happier with my purchase ! NOTE: Save your Software & drivers before upgrading to windows 8"
"I started looking for a new all-in-one when my existing all-in-one died. I wasn't sorry because it had been a rocky relationship from the outset.
I was dubious about getting another touch screen computer, since I didn't use the touch screen much on my last computer. But the specs on this machine won me over, especially for the price offered. I especially didn't want another integrated graphics card, since that had been one of the banes of my last all-in-one. So I was pleased with the superb graphics card included with this machine.
Although I was unable to see and try a Lenovo B540p in person, I took a chance and bought one directly from Lenovo because it was the best price available.
When the new machine arrived, I removed it from the box, removed the protective cling strips, put it on my desk, put batteries in the keyboard and mouse, put the related dongle in a USB port, plugged in my network cable, plugged in the power cord, and turned it on. I quickly went through the Windows 7 setup and the computer just worked.
I have had the computer for a few weeks now and here is my assessment. Bear in mind that I'm not a gamer, so I can't really say how it performs for games. I also have not hooked it up to a TV signal, so I can't say how it functions as a TV other than to say that you can watch TV on it without turning on the computer, if you wish. It has separate TV controls and a remote for that purpose.
PROS: -This machine is sleek and very quiet, even when performing resource intensive tasks. -Adjustable support. The support on my last all-in-one had a single position. -Nice foot pads on desk touch points. Maybe this doesn't mean much to others, but my last all-in-one scarred my desk surface. This machine won't do that. -Awesome keyboard. It is small, thin—very Mac-like, yet very sturdy. The low profile keys feel good to my fingers and respond well. Unlike Mac keyboards, this has a 10-key number pad, which I use a lot. I would go so far as to say that this is my most favorite keyboard to date. -10-point touch screen. I have only used this when messing around with some of the pre-installed touch apps. But it beats the 2-point touch screen on my old computer. -Except for one system error when using one of the multi-touch apps and a Chrome issue noted below, this system has been glitch free. I have been an info tech professional for a long time and have dealt with lots of computers. All computers have glitches. But this one has been pleasantly worry free. I'm very impressed. -Great sound. I didn't buy this machine for it's audio quality, since I mostly use it for work tasks. But I'm quite pleased with the audio quality. I like the inconspicuous sensory touch buttons on the front of the monitor for adjusting audio and video settings. -Clean video. The max resolution isn't as high as my old computer. But the video is fast and clean. All of the video formats I have tried play without any problem. This was a huge issue with my last computer. -Fast performance. The configuration I bought has 12GB RAM, so it ought to be fast. But the overall experience so far has been so fast and smooth that I keep thinking it is too good to be true. -HDMI out port. Most all-in-ones have only video input ports. The HDMI output port allows you to add a monitor or output the video to a large screen TV.
CONS: -Unlike the A-series machines, B-series machines will always be tilted at an angle when standing on a horizontal surface. This is OK for me for computer work. But I do notice that if you're sitting on the floor of my office watching YouTube, the viewing angle can cause the display to seem to darken to the point of not being able to make out anything. I don't have a problem with this, since I don't use this device for TV viewing. But others might not like it. -After starting the $14.99 Windows 8 upgrade, I ultimately opted to stick with Windows 7—not because I am afraid to try a new interface, but because of the incompatible features that would be lost with the upgrade. The W8 prep package first checks for incompatible features. Although I don't use the touch screen a lot, I was sorely disappointed that my 10-point touch screen would revert to 2-point touch upon upgrading to W8. I also noted that W8 would wipe out several apps that I use. Replacing those apps would cost enough that I decided to stick with W7. I like W7, but it would have been nice to move to the next thing. -Google Chrome seems to have issues with the video driver. Online video content sometimes doesn't appear unless I switch to a different tab and then switch back. I use Chrome on a lot of machines and I have never previously seen this behavior. This is a minor problem, but it would be nice if a driver upgrade resolved it.
Overall I am very pleased with my Lenovo B540p. The deficiencies I noted above aren't a big deal to me. I note them in case they are important to other potential buyers. For the most part this computer has been a delight to use. I would definitely recommend it to anyone looking for a decent all-in-one computer."
