1) Where and how do I determine, whether the I2C driver is installed on my ideaPad 320 ABR? 2) If I have it, and I have the 2018 version, where can I please obtain a 2017 version?

Hi,

please go to Windows + R (run), write devmgmt.msc, press ok.

in the main screen check I2C driver on System Devices list, then press right click and properties, go to driver snap and click rollback.

Hi there. Thanks so much for this. my driver seems to have a date of 4/1/2017, and it's offering me to update, so I guess I'll leave it alone. I more or less managed to fix all the lag, now I just need some speed...

nice, for more speed you can also check the windows search if is disabled, if in settings is disabled the "Get tips and tricks and suggestion as you use windows" on system/notifications & actions, for "occasionally show suggestions in start" in personalization / start. I've noticied that windows defender is laggin a lot the system too. you can check the ahci driver if you have configure your HDD for ahci, and clean some old regs, and deffrag

Hello, you have a problem on the hard drive i think,

it happened to me when i bought my computer and it took it around 10 hours to update the windows and everyday it gets slower and i lost around 1.5 gb or ram and the cpu is at its peak even if i am not using anything and it browses facebook so slow.

i went to Lenovo and after they responded that the hard disk was not okay from the beginning and now it works really fast. and if you have amd radeon graphic then you need to change something there if you want chrome to work better...

hope this will be helpful.

I was given my 320 as a present from my wife, so it was kind of difficult to tell her that the thing was slower than the 10-year-old Toshiba it was supposed to replace. By the time I realised that it was seriously, mind-numbingly slow, I had loaded it up with MS 365 software and transferred all my files to it so I had to find a solution. Did a full disk check, no difference; removed all the rubbish games programmes, no difference.

I read somewhere that uninstalling Lenovo Vantage did the trick for one user, and as all it appears to do is provide a different way of fiddling with desktop visuals etc, I knocked it out; total transformation. 

So I strongly recommend trying that simple step before you start mesing around with anything more complicated.

Sad to say, I've got another client's new Lenovo ThinkPad 320 sitting on my workbench and, as you all have guessed, this one (which has a 1TB Seagate) is just a rubbish, in terms of the hard disk speed as the others I wrote about before.

I was unable to try the trick that I talked about - changing the Intel IDE/ATAPI controller to Microsoft's own - because, on this machine, there is no such controller. The only thing like that present is an Intel Chipset SATA RAID Controller and this has no option to use a Microsoft driver as an alternative. I did have the ability to upgrade it to the lastest 2018 version and did do that - but no difference.

Out of curiosity - but fearing the worst - I went into the Bios (via the official route: PC Settings> Update & Security > Recovery > Advanced Settings) and changed the mode from Intel SATA RAID to ATAPI but, as I expected, this caused the machine to be unable to boot, so, dabbing F2 repeated as the machine restarted, I went into the Bios and changed that back again

Backing away from that dead-end, I followed dooce's advice and uninstalled the Lenovo Vantage - no difference - I then went to uninstall the two remaining Lenovo apps, one of which was Lenovo Settings. I ran that app first and was told that it was no longer needed, because its functionality was wrapped into Vantage! Anyway, all three Lenovo apps are now history but that made little difference. And I had rebooted after each was zapped.

So what should I do? Well, I'm advising the client to get her money back from where she bought it (Lenovo directly) not least because the old Win7 Samsung laptop she brought to me at the same time - so I can copy the data  onto the Lenovo - now performs massively better than the Lenovo, despite it being six years old and having a Pentium B950 2.1GHz, compared to the Lenovo's i3-7100U 2,4GHz CPU. And I haven't yet finished tweaking and twiddling - though I had on the Lenovo, to no good affect.

Okay, the Samsung has 6GB of RAM, compared to the Lenovo's 4GB but I don't for a minute think that's relevant here - the Lenovo is just not fit for purpose.

I've attached a couple of screengrabs so people can see the relative hard disk speeds of the two machines - and see just how horribly erratic the Lenovo is across different size of file reads and writes.

Sorry, that last posting did not contain the speed test from the Samsung - here it is in this one.

Nope - no significant difference.

This was in reply to Vijendersingh's comment:

Hey, I had the same problem when I bought the laptop but now it is working fine as I did 2 things:

1. I increased the Virtual ram of every disc. Made it equal to the actual physical RAM

2. I uninstalled the MacAffee anti-virus and installed other antivirus. I must say there is something wrong with McAffee.


Now it is working perfectly fine. Let me know if this works for you too

Er..... scratch that. Turned the thing on a day later and it was just as slow as before. Going back to supplier first thing tomorrow. What a rubbish bit of kit - cannot believe a supposedly reputable company can produce such a sub-standard product.
