Here is the one solution that could work out for every single WORTHLESS AND USELESS laptop . See attached Single Rank RAM. 

THIS WORTHLESS PIECE OF CRAP WAS USABLE AFTER I HAVE INSTALLED THIS CRUCIAL RAM -8GB. ONE COULD DO THIS BY ONESELF

THERE IS NO NEED TO SPEND MONEY ON SSD . RAM WORKS FINE. ITS AVAILABLE ONLINE.

Ok. If you have this laptop and you came to this thread hoping to find a solution, let me tell you this: IT'S ALL WORTHLESS

It is 2021. I bought this laptop new in 2018. Since that very moment it has been unbearably slow. I first visited this same thread in 2018 hoping I'd find a solution. I tried literally EVERYTHING that has been suggested in this thread over the last THREE YEARS (except, of course, returning the machine and getting a refund, which now I'm a bit late to do...).

Here's what I did over the course of three years (spoiler: NOTHING WORKED!)

1. Wiped the factory Windows 10 install clean, deleted all partitions, downloaded a fresh copy and reinstalled fresh. This meaning NONE of the bloatware was present. Still slow.
2. Changed the UEFI to Legacy, just in case. Still slow
3. Updated the BIOS and ALL the drivers. Still slow
4. Disabled the Intel Rapid Storage thingy. Still slow
5. Changed the virtual memory settings. Still slow
6. Disabled all unused Windows services. Still slow
7. Upgraded from 4gb to 8gb ram. Still slow
8. Went with the most expensive option of upgrading to SSD. Which after reading so many comments of how slow the original HDD was, I REALLY hoped this might solved it. It kinda made it slightly faster, but STILL SLOW.

So you see, tried both the software AND hardware solutions. So let me spare you the reading of three whole years of posting confirming to you that there is really no hope for this girls and boys.

As someone else has said, the HDD is terrible in this model. 

In mine.. with nothing open.. the HDD is read/write at 100% capacity. Windows 10 itself will slow your speeds down some, but not to the extent that it's unusable. It's just an advertiser's OS that caters to marketers and trackers rather than performance and overall functionality. 

With that being said, I remedied mine by replacing the HDD with a 7mm nand SSD, 9.5mm ssd adapter and then I went ahead and replaced the RAM with a 8gb Sodimm DDR3 1600 card.

This, combined with a factory reset, has the laptop like new.

Have to admit that there have been times when I had thought the same. Having tried most ofthe options noted in this thread, late last year I finally decided to take the plunge and replace the HDD with SSD. It wasn't particularly expensive - a 1TB SSD cost me about £35, plus the cable (another £5 or so), which has significantly increased the performance. I did the SSD upgrade myself, and appreciate not everyone has the confidence to do this, but it has been worth it.

Yes, admittedly, there are still the odd occasions where the laptop does "have a moment" where it locks up, but in general, I'm now happy with the performance. Just a shame it took me 2 years to get around to doing this!!!!

Honestly, I'm amazed you waited so long before purchasing an SSD.  It think after my first fresh install of windows I realised the Hard Drive was absolute junk and swapped it out.. This was 3 years ago and it's run flawlessly since.  It's a shame Lenovo sold the laptop in that condition (i.e not of merchantable quality), but I doubt you'll see them admit that.   At the end of the day it's a cheap laptop, even the guy in the store asked me if I was sure I wanted it..
