Inspiron 5559 - Laptop is very slow and lags
I have a Dell Inspiron 5559 (4GB) with Windows 10 and Quickheal Antivirus installed in it. Everything is regularly updated. I often just shut the lid of the laptop without putting it into sleep or hibernation. The problem is the PC takes lot of time to come to the PIN screen. Secondly, while working on the laptop and using only Word, Excel, PDFs - it takes lot of time to swap between screens and there is a sustained lag many times while working. Furthermore, if I double click on any file in my Google drive or local drive it takes time to open and image files take a lot of time. When clicking on the windows button there is a lag in opening the menu or to open notepad. The laptop has 95% free space in its HDD. Looking for some advice on improving the performance of the laptop. Thanks!

My same model was running extremely slow for an i7 6th gen. In task manager my DISK would be running at 100% for a while after each boot-up and wake-up from sleep.
After coming across another forum the solution that worked for me was to update the intel RST (Rapid Storage Technology) driver direct from intel site. DELL-update would fail to pick this up and the one on the Dell support site was an older version than the one I had already installed.
Intel-Rapid-Storage-Technology-Driver
I installed the SetupRST.exe file from the link above.
Good luck!

I have the same laptop and before my hard drive failed (it was an HDD), I was having plenty of slow down issues. If I am correct, the HDD on our laptops is considered to be bottlenecks. They drag the rest of the performance down. I ended up replacing it with a 1TB SSD from Sandisk and holy, the change is VERY noticeable in terms of startup and read/write speed. Instead of waiting normally 5 minutes to get completely loaded in, it takes 5 seconds from sleep and maybe a minute for the startup.
If you're curious, this is the one I purchased from Best Buy: https://www.amazon.com/SanDisk-Ultra-NAND-SATA-SDSSDH3-1T00-G25/dp/B071KGRXRG/ref=mp_s_a_1_fkmrnull_1?keywords=sandisk+3d+ssd+1tb&qid=1558141350&s=gateway&sprefix=SanDisk+3d+ssd+1&sr=8-1-fkmrnull
I have to warn you though if you decide to get this that you will not be able to use hibernation mode (or shouldn't as I guess I can shorten the life of your SSD and void any warranty if used).
It's the sad reality that this is probably your best solution overall, but if you don't want to spend money on another hard drive, you can upgrade your 4GB of ram to a max of 16GBs (two 8GB DDR3 sticks). You can view the listing for that here: https://www.crucial.com/usa/en/compatible-upgrade-for/Dell/inspiron-15-(5559)#MEMORYFilters
I upgraded both of these and it made a huge difference. If you have any more questions, feel free to reply. I suggest not opening up your laptop unless you're comfortable doing so and follow proper safety procedures to make sure you don't cause damage to yourself or the computer.

This worked for me. Thanks Babapatha. My bootup time went down from 15 minutes to 5 minutes flat. And all programs also seem to be responding much faster. After 4 years of frustration, your solution was God sent.

Yes I got the same performance problem for 2 months.
I added RAM, added SSD etc but nothing changed.
Although it is the original adaptor, bios was telling that "unknown adaptor. so system performance may be down".
I tried a new adaptor (not Dell brand) but nothing changed.
Finally, I changed only the pin side of the adaptor (not the main part) and it started to run fast as old good days.
Note : I read and read forums and understood that, Dell is using some software to prevent you using "not original" spare parts and if you use, making the CPU etc slower, so you are getting forced to use Dell spare parts otherwise you are crawling on the ground. (It is just the reason, why my new (other brand) adaptor didn't work, altough it is also 65W). Possiblt even a minor difference is detected.
Anyway, simply main reason may be the adaptor pin or power jack pin as they are very simple and thin. This is my experience. Regards.

I suggest starting a new thread on this issue as it seems a little too specific for the original topic.

Hello,
Not sure if you'll see this but...
I have the same issue going on.
The adapter is not recognized and everything is running SUPER SLOW>
I want to get another adapter, to try to fix this issue.
I found a charging cord / adapter, that is a certified dell power cord... but after reading your comment, I was wondering what you used to replace just the pin?
Or, if anyone else can see this, any recommendations?

I found out a workaround which does not require to buy a new power brick / power cord or mb replacement, and it is: install Linux instead of windows. I tried both Ubuntu 20.10 and a distribution based on Gentoo, and in both cases the GUI was snappy and the battery got charged.
I don't know why, but it seems that the Linux drivers do a better job than the dell-provided windows ones...
