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.)

I'm thinking about picking up a USB-C charger for my Lenovo IdeaPad 15".  I see a range of wattage options and I was thinking of going for a 90W charger so that I could bring that with me on the go and leave the Slim Tip at home.  Is there a maximum wattage the Lenovo 720s is willing to accept from the Thunderbolt USB-C port?

I have only had this laptop for a month or so,  but the Thunderbolt usb-c port stopped working. I can still use this port to charge my laptop, but it won't connect to any other devices nor output video to an external monitor. Has anyone encountered this problem before? Does it mean I need to send my computer back for a repair? Thanks.

The Ideapad 720S-13 is great, but I found out it's temperature is so high when charging ( almost 60 C and the CPU load is very low ).If I unplug the charging cable, the temperature gradually goes down to 40 C ( takes about 5 mins ).I think there is something wrong, maybe Lenovo can release a BIOS update to fix it ASAP? ( I am already using the latest BIOS )

Hello all, I have a problem with my Thunderbolt 3. I had to do a clean install of windows 10. I used the built-in function of windows 10. And did a hard reset, so no bloatware survived.

Dear helpy helpers, I am experiencing a heap of trouble when using T490 and Thunderbolt 3 Dock Gen 2 together.When we recieve a new machine, we reinstall it, with a clean latest version of Windows, and run TVSU for the lastest drivers. Software wise, they get Office, Visual Studio, ReSharper, SQL Server Management Studio and Symantec. Nothing fancy. The last 3 machines hav had issues with the docks. The docks are 135W (cable plugged in the correct power port on the dock). Cable for the PC is on the back and not the front. Screens that wont run full resolution, no ethernet, no charging and the like. Checking the Thunderbolt Control Panel, the dock is connected. Reinstalling wont solve the issued, but getting new motherboards for 2 machines worked somewhat. I've been managing Lenovo laptops for 10 years now, and though i don't see myself as an expert, I have seen quite a few different models, and experienced different issues with docking solutions. Though. Nothing. Like. These. Thunderbolt. Docks.  Is anyone else having trouble, or am I the only one fighthing this? I am thinking about running back to Windows 10 1809 instead of 1903, but I dont really like having to be vary of backwards compatibility with a simple setup as above.  Any help would be hawt!

Hi, I'm having issues with my external 4k display to only be able to operate at 30Hz. I have my laptop connected to a generation 2 Thunderbolt 3 dock via the provided cable, and from there I have tried both DisplayPort and HDMI cables (several) to connect to my display.All the technical information I have seen says that my laptop plus the dock should be able to operate at 60Hz even at this resolution, but I'm unable to lock down the settings that enable me to do that. I have pulled the latest BIOS, TB3 FW, display drivers, Intel chipset drivers from the product page.My screen is: AOC U3277FWQ if that matters. I'm running Windows 10 Pro 1809. Has anyone battled with the same issue? I'm running out of ideas on how to solve this. The HDMI port on the side is apparently only 1.4 so this would only support the [email protected], but I'm not using it at the moment. If I set the screen to 1920x1080, I can set the resolution to 60Hz. Best regards,_tero

I have a P1 GEN2 OLED. While the internet is flooded with complaints of the OLED screen itself, the thunderbolt 3 port of my P1 GEN2 magically stopped working for no reason.  I have been using the laptop with an external display ever since I got the laptop. All went well. Suddenly from yesterday, the external display starts turning into a blue sreen with "NO SIGNAL" shown on it.  I had a windows cumulcative update (KB4532693) and windows security update (KB4524244) yesterday and I suspected that the update might be the culprit. I rolled back the OS. No change. Still NO SIGNAL.  I searched this Forum. Played with Thunderbold 3 menu in the Bios. Everything was enabled and every single option of "security level" was tried. Still NO SIGNAL.  I checked Intel Mangaement Engine software. It is already the latest version. Reinstalled it. Still NO SIGNAL.  I checked Nvidia driver. Latest version already.  In sum, the problem is: the thunderbolt port is still able to power the extenal display but just simply does not pass signal to the external display. HDMI port, however, still passes signal if use an HDMI cable.  I want to give it a shot here to see if anyone has experienced similar issues and how they sovled the problem before I call Lenovo technical support, the staff of which does not seem to know more than some people here on this Forum.

It seems like the bottom left corner and the top right is higer then the two other corners. So everytime i lay my hand down to type i can clearly feel the bump caused by the lack of contact with the table. I have tried to bend the base of the laptop to fix it, but it dosent work. The problem might even be that the whole base is not flat, im not sure.Dont know what to do about this, and i really dont feel like sending my laptop to a service senter as it would take quite a while before i would get it back. But if that is the only option i guess i just have to. All sugestions apreciatedThanks in advance

Ideapad 720s 14ikb The jbl speakers on this laptop were impressive when I first bought it about 7 months ago. About a month ago the speakers suddenly became very quiet to the point where at 100% volume it's still quiet. The sound quality is very "tinny" as well. Base is terrible. For example playing the witcher 3 used to sound pretty decent using the laptop speakers and was way too loud at 100% volume. Not I can't get it loud enough.  I'm not possitive what caused this. Was it a recent windows 10 update? One of the bios updates? Dolby? Something else? I've tried many times uninstalling and reinstalling drivers- rolling them back, etc. No fix. I've tried all the sound settings and fixes that seem to work for other people. Anyone else having this issue or know of what could be causing this?Thanks

Try to check if there is any issue with the functionality of those keys.
