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.

I am experiencing strange mouse pointer behaviour after my laptop has been running for a while and a program is working in the background. The mouse pointer is displayed in a very low resolution, while jumping up to another part of the screen. So usually, the mouse cursor looks like this:  But when the problem occurs, it looks like this (and jumps up to another part of the screen):  As mentioned, the problem only occurs after my laptop has been running for a while (this may take a day, but sometimes only an hour) but when it does, it keeps occuring untill I restart. This has been happening since I bought the system about two months ago. System: Lenovo ideapad 510S14ISKOperating system: Windows 10 I already tried:- updating my drivers (using Lenovo Companion)- reinstalling windows (while keeping my files)- uninstalling Lenovo System Interface Foundation as recommended here- unchecking the box "enhance pointer precision", also as recommended here The problem occurs both with my external mouse plugged in and plugged off. Any ideas what might be causing this problem?

Maybe related to this issue, maybe not: I also noticed a strange resolution in a few other places. For example, in the image below you can see that the text in the left box is displayed much sharper than that in the right box.  This occurs also after my laptop has just restarted and is of course much less anoying. Nonetheless, I thought it would be interesting to mention as the two issues might be related.

There should not be any gap when the laptop is closed but on the right side, there is a decent amount of gap which results in dust and there appears to be a slight bend in the screen. How did this happen and what should I do?

Hi, I have Lenovo U41-70 with 64-bit Windows 7. My Nod32 antivirus is up to date. For more than a year, all Fx keys were working as expected, F1 key muted sounds, F4 key closed current window, etc. However, some time ago the F4 key suddenly started to exhibit very strange behaviour. Instead of closing windows, standard F4 keypress is sent, plus Shift and Win keys are toggled and remain "pressed". (I found this out using windows on-screen keyboard - see attached picture.) Moreover, other strange behaviour can be noticed after F4 is pressed. For example, minimizing a window to tray and opening it again results into a new window of the particular application to be opened, or when a desktop icon is clicked, all icons to the top-left are selected. All of the problems persist from the point the F4 key is pressed until the laptop is restarted or until Shift key is pressed (and it starts again every time F4 is pressed). All other Fx keys are working fine. I have already tried changing the bios hotkey option to "disabled" and then back to "enabled" (the state where Fn key does not need to be pressed to access special Fx functionalities), but the strange behaviour of F4 is back once the hotkey option is enabled again. I also tried plugging an external keyboard - the F4 and Alt+F4 works ok when pressed there. I would like to make the F4 key work as it used to. What can I do to resolve the issue?

Hope somebody can help with this as I've been researching for about a week now...

Macbook pro 15" early 2011 i7 2.0ghz

The issue: magsafe only works intermittently after battery expanded and failed. Its a bit random if I unplug it a few times and jiggle it about it may come on and work as it should..once it's on it stays on....

If it's working and I quickly unplug and replug 95% it will come straight back on.. Its not a short or cable issue in the magsafe..as I've tried 2 new ones so far.. There was no damage liquid or otherwise apart from the expanded battery issue...

Steps taken:

Smc/pram reset

Brand new magsafe (original)

Swapped out dc in board

Brand new battery

Different plug sockets

Different power cable

After trying another magsafe the issue remains.. The best it's been was at my work where it always came on but took between 5-15 seconds. At home I'm trying it and it's just hit and miss. Just hope it isn't logic board smc damage due to the previous battery failure. But then why would it work normally when it does? Could it be the dc in connection on logic board?. In istat the dc in is showing 1.8a and the charger behaves normally when it works..

Any help would be great,. id like to sort this myself so please don't suggest i take it to apple,. thanks in advance,..

Hi,Have been using Ideapad Z410 from past 6 months.  From past week the Laptop shuts down without warning, and the battery level is at 99% or 100%.  Only when the unit shutsdown, and when I start up again, that the battery indicator starts from 0 and goes to 99% or 100% and stays there.  I have also doen the Battery Meter Reset, but of no benefit.What is the problem, and what should I do.Should I claim under warranty ?

A:Idepad Z410 battery always at 99% or 100%

I wouldn't expect much of an answer from them, the same happens to the Z510 I have and it happens to the Z500 models before it, they'll tell you to send it in under warranty but that will not solve the problem as it will happen again after a few months and I need the laptop for work, I didn't buy it so that after half a year I would have to send it away for 2-3 weeks, I bought the thing because it is needed here. They need a battery firmware update but that too is too hard for them to do. These problems are being experienced by people worldwide and I am seriously considering reporting them to watchdog here in the UK. They should not be shipping laptops that have known issues and then offer no fix.

I  bought this laptop lenovo idepad 510-15ISK from a shop in Greece. I added an SSD and upgraded the RAM the same day following sellers advice that the upgrade won't harm the warranty. The same day I detected that laptop were electrocuting me and the next day I returned the product to the seller for replacement. They verified the electric drain and the technician recovered the original HHD and removed the extra ram that I added so as to give it to the official technical support. I have been told that only if the technical support  say that this is a problem they will either replace the laptop or return my money back.It seems though that the technical support changed the motherboard of the laptop (approved that SSD and RAM upgrade didn't harm the laptop) and they don't approve the replacement or my money back. This laptop is no longer a new laptop but a refurbished one!!!!! I have already gone to local authorities for local seller, lenovo and official technical support for trying to cheat me and I am already contacting with local media to raise the issue in the Greek market about the tactics of lenovo. Can you please suggest me any other ways before this goes public not only in Greece but also in more European Countries?

Hi -  I hope someone can help to identify what the issue is here, please? Bought a 510s-14 laptop back in June and and been using it fine until a few weeks back. When using the browser (Google Chrome), these 'squares' as can be seen from the photos below come up on the screen. I then have to shut the browser down and open it up again and it seems fine until it randomly happens again the same day or two days later. There is no pattern and I'm not doing anything in particular when it happens. Run the Lenovo diagnostic tool, which found nothing and everything is upto date on the machine. Any ideas, please?

That may be a glitch in Chrome from a few years back resurfacing that involved using the GPU for its 2D Canvas rendering, which is enabled by default. The first thing I would do is go to https://pcsupport.lenovo.com/hu/en/products/laptops-and-netbooks/500-series/510s-14isk/80tk/download..., and install the latest "display drivers and Video Graphics" drivers for your system if not already installed, because updated drivers may resolve the problem.  If not, you can open Chrome, and in the address bar type or paste:  chrome://flags/   which will open a page with some of Chrome's experimental features, locate Accelerated 2D canvas (should be 3rd one down) and click the Disable button below it. Best of luck,

If i let the notebook idle for 2 min it goes dead silent but starts again even if i just scroll down a homepage. And even if i start programms whicht take more resources, the fan does not get louder. Is there anyway to controll the fan? Help would be really appreciated, Thanks in advance and sorry for my bad english

Looking into buying the Lenovo 510s, I see "Up to 8GB" listed as supported memory. However, I've done some research and some Lenovo laptops, while they also only support 8GB of memory officially, can be and have been safely upgraded to 16 GB of RAM. My question is: Is this true of the 510s? The CPU specifications page from Intel for the 6200U/6500U both say 16 GB is no problem, and Crucial even has a 16GB dimm listed as "guaranteed compatible" for this model--I'm not sure, though, if this means it will work but only recognize 8 GB or if 16 GB is truly Ok. Is there any reason 16 GB could not be used? Perhaps some motherboard memory controller limitation? I would love to have some input on this before deciding on whether or not to purchase this laptop. Thanks!

Hello Everyone in this forum
 
Bought a Lenovo 510 sff desktop, with the sole intention of adding more stuff and upgrading the system with time.
But I found it to be very difficult, and need more information from users here.
 
Firstly: this system came with only 4 gb ram. I have put in 16 gb ram now. Can i put in 2 x 16 gb ram modules to get 32 gb total in this system?
 
Secondly: I thought there would be 4 SATA ports to support 4 drives maximum. But this system is showing only three SATA ports on motherboard; Also the computer case only has place for one HDD, and one slim ODD. Not possible to add another SSD in this place. Is there an option to now remove the ODD and put in a SSD. Terrrible option provided in this SFF.
 
Thirdly: The Windows 10 OS was preinstalled without any media given, in case of OS crashing or getting corrupted, how do i reinstall or repair the OS? Do i have to make any OS backup or recovery media? Where and how is this done?
 
Any solutions or ideas for upgrading the system  given here, will thankfully be received.
 
Regards and thanks to everyone here

Wondering what RAM modules people have upgraded their Lenovo Ideapad 510s (80UV001BUS) with. Looks like it only has one slot and is only upgradeable to 16GB. What about speed and latency? Crucial has different speeds and latency listed. http://www.crucial.com/usa/en/compatible-upgrade-for/Lenovo/ideapad-510s-(14-inch) It has ones at 2133MHz, 2400MHz and 2666Mhz and latencies from 15, 16 and 17. Only a $14 difference between their cheapest 2133MHz and their most expensive 2666MHz. Newegg sells other modules at the 2666MHz speed that Crucial says is the max that seem compatible. Patriot Viper 16GB DDR4 2666 PV416G266C8S at CL18 and HyperX Impact 16GB DDR4 2666 HX426S15IB2/16 at CL15. The numbers make the HyperX look like the best for this laptop with it being $14 more than Crucial's fastest module. Newegg also has 2800MHz and 3000MHz offerings too. Does this chipset support those speeds? The 2800MHz being made by Patriot and the 3000MHz made by G.SKILL. The latency on the G.SKILL module is CL16, so pretty good but considerably more expensive. $27 more than Crucial's fastest and $13 more than HyperX's fastest and its on sale right now (retails at $180.99). Whats the fastest RAM the Intel HM170 chipset can support and will this laptop allow it? Intel shows that the i7-7500U supports up to 32GB memory size and DDR4-2133, LPDDR3-1866, DDR3L-1600 memory types, yet Crucial says it can support 2666MHz, feeling confused. My main goal is to p...

I bought lenovo y500 two days ago in INDIA.  In the lenovo energy management system 8.0, I found a battery calibration option and decided to do it.  The steps mentioned there were as follows. 1. Full charge2. Full discharge  The process performed full charging followed by complete discharge of the battery which caused the laptop to shut down.   When I tried turning on my laptop, it could not start.  The battery charging indicator LED wasnt switched on even though the power cord was inserted into the laptop.  I could start the laptop only after removing the battery.   Once the laptop was on, I inserted the battery back in and it began to charge.  After about 50% of charging, I removed the power cord and inserted it again.  Now the battery couldnt resume charging.  I again had to shut down the laptop and repeat the above steps of inserting battery after switching on the laptop without battery.  Only then the battery would resume charging. After this, I decided to allow the battery to charge to 100%. But, the charging remained stuck at 99% and could not fully charge the battery.  When I removed and reinserted the power cord, the same problem persisted of battery not resuming charging. Please help me with this problem.  I read on few forums about uninstalling microsoft ACPI which supposedly solves this issue.  However, ACPI returns back after I restart my laptop.I also tried switch...

A:LENOVO Y500 BATTERY NOT CHARGING AFTER USING LENOVO'S BATTERY GAUGE CALIBRATION

 
 
ADMIN Edit - While the original post below is marked as the solution, because service will be required if the battery will no longer charge after performing a battery reset, I am adding a Lenovo update here to confirm.   Normal operation will allow the battery to relearn its capacity characteristics when using the battery reset function.  Typically this is not needed in normal use..   Batteries are equipped with a safety feature that will permanently disconnect them (like a fuse) if cell imbalance or an internal short is detected.   This tends to be statistically infrequent, but also normal, and would require a battery replacement.  (Batteries have a 1 year warranty).   This battery feature can also  produce similar results to what is being discussed in the thread, so it should first be considered by service.   This particular  forum discussion also involves a situation that could affect a limited number of systems, and could lead service to replace the system board during warranty.  
 
If your system experiences these symptoms, please contact service during the warranty period.
