You did not attach the summary page but I expect it did not complain.

Right click on C: and select Properties then Tools.  Select Optimize.  On the new page select Optimize.  On mine it only took a minute to report back that the drive was 0% fragmented.

Disk optimization - done. A screenshot called disk optimization PNG is attached.

 

I see your version of Intel Rapid Storage Technology Driver and Management Console is slightly older than the one on the Dell Support webpage so try and update it.

Intel Rapid Storage Technology driver version 16.8.3.1004, A06 downloaded and installed. From Dell's support site.

Did you mean this version of the driver?

 

Intel Dynamic Platform and Thermal Framework Driver
Downloaded and installed Intel Dynamic Platform and Thermal Framework driver version 8.3.10209.6897, A12. From the Dell Support Site. Did you mean this driver version?

The drivers were downloaded from this Dell Support Site:
https://www.dell.com...RIUT090/drivers

 

 

Rerun Latency Monitor for 1 minute and post the summary and a screenshot of the drivers tab.  
A summary and screenshot of the driver penalty are attached.

Your computer CPU clock speed is very low, did you change CPU multiplier within BIOS setup utility?

 

 

No, I wasn't doing anything.

Disable your WiFi and rerun Latency Monitor for 1 minute.

See if you can install:

 

Sterownik Wi-Fi kart Intel 3165 i 7265

 

from the Dell site.

 

Then try latency monitor again for 1 minute with WiFi connected.

[piotrzyna]

Intel 3165 and 7265 Wi-Fi driver downloaded from the Dell Support website.

When installing there was only the "repair" option, I clicked and at the end I got the "fixed" message.

I did a laptop reboot.

I am seeing RuntimeBroker.exe which often means an update is in progress.

 

Go into Settings, Update & Security and see if it has any updates in progress or if there are any updates available.  

 

If not let's try resetting TCP/IP:

 

Open an Elevated Command Prompt as before and type:

 

netsh  winsock  reset  catalog

 

hit Enter

 

netsh  int  ipv4  reset  c:\resetlog.txt

hit Enter

netsh  int  ipv6  reset  c:\resetlog.txt

hit Enter

 

 

Reboot.

 

Wait about 5 minutes after getting to the desktop to make sure all of the setup is finished then rerun Latency Monitor for 1 minute.  (Make sure all browsers are closed when running Latency Monitor)

[piotrzyna]

I was looking for an update, is there something new - I got a message that there are no new updates.

 

Commands executed

 

I waited 5 minutes.

Browsers closed.

The report is attached.

Looks better. 

 

Try the UserBenchmark again.

[piotrzyna]

Done

Still looking slow.

 

I am looking at the Speccy log.  It says you have no battery.  Is that correct?

 

Do you have the charger that came with it or are you using a generic (non Dell) charger?

 

Will Speedfan work on your PC?

 

http://www.filehippo...nload_speedfan/

 

Download, save and Install it (Win 7+ or Vista right click and Run As Admin.) then run it (Win 7+ or Vista right click and Run As Admin.).

 

 

I usually use it to monitor temperatures but on some PCs it also shows voltages.  IF it works can you give me a screenshot of the main page.

 

Let's also see if minitoolbox will work:

 

Please download [url=https://www.bleepingcomputer.com/download/minitoolbox/[/url], save it to your desktop and run it.

 

Checkmark the following checkboxes:

Flush DNS

Report IE Proxy Settings

 

Report FF Proxy Settings

 

List content of Hosts

List IP configuration

List Winsock Entries

List last 10 Event Viewer Errors

List Installed Programs

List Devices

List Users, Partitions and Memory size.

List Minidump Files

Click Go and post the result (Result.txt). A copy of MTB.txt will be saved in the same directory the tool is run.

 

[piotrzyna]

The battery is physically in the laptop. But it has long been useless.

The power supply is original Dell.

 

 

Speedfan.

Screenshot attached.

 

 

MiniToolBox
Result attached.

Can you remove the battery?  

 

A bad battery can cause a slow computer by loading down the power supply.  It is better to have no battery than a bad one.

 

Appears to be a lot of work to remove the battery but I think it really needs to be done.  There is a service manual on the documentation page on the Dell site that explains how and you can watch a video:

 

He removes the battery at the 6 minute mark.

 

I use an old credit card to pry the back off instead of a metal tool.

 

Also be very careful with the screws.  Haven't worked on a lot of Dells but HP is fond of using many different screws.  I draw a diagram showing where each screw is and then place each screw on the diagram as I remove it so I know where it goes.

[piotrzyna]

Battery already removed, using your video, your tips.
And see what good happened:

 

I heard some noises as I turned on my laptop.

I clicked Solve sound problems ino and a positive surprise, there is a sound!

 

The touchpad works fine too!

The left and right buttons work too, the rest are fine too!

Youtube - videos load better but slowly anyway, sometimes they stutter, you can hear crackling in the internal speakers of the laptop, but it's still much better.

 

Unfortunately, the keyboard still does not work. Not all buttons work, min. 7, 8, 9, 0 and F4 to 12 and 7 to 0 and PrtScr, Insert

Probably, however, I will have to physically replace the keyboard.

 

Delay monitor - report attached.

The Internet works faster too.

Glad to hear that it helped.    Was the battery swollen?  

 

Let's try getting rid of some of Windows spyware:

 

Search for

 

task scheduler

 

hit Enter

 

Click on the arrow in front of Task Scheduler Library then

 

Click on the arrow in front of Microsoft

 

Click on the arrow in front of Windows

 

Click on Application Experience.  In the next pane to the right, right click on each Task and Disable.  Should be three or four (later versions) tasks.

 

Click on Customer Experience Improvement Program.  In the next pane to the right, right click on each Task and Disable.  Should be two tasks.

 

Download OOSU10.exe:

 

https://www.oo-softw...com/en/shutup10

 

Download and Save it (You will get a popup while it's downloading.  You can X out of it)

then Right click and Run As Admin.  (I've never tested this on a non-English system so don't know if the software will run)

Allow it to make a System Restore Point.

Click on Actions then on Apply Recommended Settings.

 

Close the program and reboot.

 

Rerun Latency Monitor and post the summary.

 

Also give me another Process Explorer log.  Please wait a full minute after starting the program before you make the log.
