I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi, I'm looking at buying this laptop, but i came across a few questions: 1) Can this laptop support up to 32gb RAM as it is mentioned in some youtube reviews? 2) Can this laptop support video through the USB-C port as well, or just data? I'm looking at connecting 2 portable USB-C monitors, 1 through the Thunderbolt port and the other through the normal USB-C port. 3) Is the Thunderbolt port 2 lanes or 4? 4) Is this 4k screen anti-glare as well? 5) How would this 4k screen work connected to 2 FHD portable monitors, in terms of resolution? 6) Is this 4k screen suffering from backlight bleeding as some reviews suggest? Thanks in advance.

A:Lenovo Ideapad 720s 15IKB Touch 4K - specs

Answers to some of your questions: 1) Yes, it supports up to 32GB RAM, however you would need two 16GB 2400MHz DDR4 SO-DIMM modules, which are rather expensive.2) I can confirm, that one USB-C port supports ThunderBolt 3 and DisplayPort 1.2a connection.4) No, it's a glossy panel.6) Most of IPS screens suffers from backlit bleeding problem. It's mostly depends on unit, which you've receive.

Having trouble here would be super grateful for your help. I connected one external monitor to this alptop but failed in connecting a second monitor to it. My Ideapad 720s is a 4k laptop and so are both my external monitors. When I connected the HDMI cable into the USB port on my laptop the monitor was VERY blurry! So I was forced to use this adapter to plug the HDMI into it and the adpater pligged into the USB-C on my laptop. This is the adapter I used: https://www.bestbuy.com/site/j5creat...?skuId=5930600 So that adapter worked to connect one external monitor but I wasn't able to get a 2nd monitor to work sucessfully. I don't know what I'm doing wrong? Thanks for any input!

Brand new 720S from Lenovo.Fully updated Win10.Fully updated Nvidia MX150 drivers.Fully updated Intel drivers. Because the 720S is using OPtimus, I'm unable to get the MX150 to display, so I have to use the Intel 620.The best I can get is 30Hz at 2560x1600 with the Intel. Anything higher creates odd errors or a blank screen. With other laptops using a GTX1050 GPU there are no problems. Anyone know how to get the Intel refresh rate up to 50Hz?Or better yet, is there a way to force the MX150 into controlling the resolution and refresh rate?

Hello, I've had the Lenovo Ideapad 720s 15IKB with an i5 7300hq and GTX 1050 TI Max-Q design for about a month now, and occasionally use it for gaming. The only game I really play is GTA V, and it runs well on high settings at 60FPS for about 5-10 minutes, and then the CPU power throttles and the game drops FPS down to around 45. I've measured this with ThrottleStop. Temperatures are very manageable according to MSI afterburner and Open Hardware Monitor, far away from thermal throttle (73C/165F on avg). It took me a while and some research to figure out that the CPU was power throttling. Is there anyway to fix this? As far as I can tell, the CPU boosts just fine to around 3.1 (I believe that's the max boost?) and then when it throttles after a couple minutes of gaming, it drops down to around 2.5 or less, and this kills the framerate. This pretty close to being a deal breaker for me (I know this laptop was not made for gaming necessarily, but considering the hardware it has, it should be more than capable). I'm just wondering if there is any fix to keep the laptop from throttling, or at least throttling as much as it does. I am ok with repasting the CPU and GPU if it means higher temps.

A:Can't connect external monitor to Ideapad 320-15IKB with HDMI cable

Hi, welcome to the forum.
 
My guessing on this are  will be:
 
1) Try the "Windows Key + P" combination, try the extend and duplicate to see if you get an image on the monitor.
2) You already tried different HDMI cables, it may be interesting to also check some other TV that  you may have arround to see if you get image. Also, if you use some apdater (DP to HDMI or other) it may be interesting to try some others.
3) Go to  the support site of the "Ideapad 320-15IKB" and update the BIOS and the Video drivers. Lenovo Vantage can also help you to have you drivers up to date.
 
After trying that, if you get no good results, maybe it is some hardware issue.
 
Regards

Had to perform a factory restore with the factory image from Lenovo USB Creator. The Dolby Atmos Gui to change the sound settings is not listed and no matter what I have tried its not installing. The only way to change the settings profile is to go into Lenovo Vantage. Be it as some may find this as a gimmick, I find the utility useful and would like to get it back. Its obvious the authorized factory image for this laptop does not install the same image with the preinstalled apps that came with it.  Any helpful suggestions would be appreciated.

Hi Support, I bought my IdeaPad a month ago. After few days of using i saw a black horizontal line on the screen. I opened a ticket and sent my laptop for a warranty repair. Today i recieved my laptop, and black line issue was fixed. BUT!!!! After the 'repair' two new issues are intoduced!1) This is the craziest to my mind - my screen is assembled with an issue. It is curved in the middle of the screen, and i'm afraid if i push that a place a bit harder my screen will be damaged. Do you have a quality Control service? I cant imagine your engineers have not seen what they done. 2) After repair i can see a backlight bleed on the bottom of the screen. It was not there before, so it's an issue after the repair!  I'm totally mad! How come you could make two critical issues from one? I need your help, even if that sounds funny

Hi, I am writing here because i am concerned by an issue that happened to me today. I came home from school where i was working on my laptop, then once i got home i picked my laptop to work again, but i instantly noticed a big crack on my screen going from the top, near the camera, spreading until it reaches the bottom left of the screen. I decided to call the warranty service from lenovo and explained them the situation, but the customer service representative told me that the warranty doesn't cover physical damage and and that i had to send them the computer so a technician decides whether it is my fault or not... I am very concerned by the situation because i am sure that that crack isn't the result of a bad usage of the product from me, i always take care of it and i have it since almost 2 months.  Considering that, i just wanted to know if something similar happened to other people here and what did the technicians decide ?
