If you're using laptop and suddently shutdown unexpectedly...
or when you're working normally such like:
When you're searching and browsing GMAIL inbox appear an alert: You're offline! results will be limited.
While the Power cord plug-in? and your internet connection working normally?
but your laptop is very hot... Overheating!
Here's my tips and tricks that I'm using it from many many years ago:
My Old laptop hp elitebook 2540p battery could be leaked...
which make BIOS system within your laptop working not correctly.
Just Dropped out the battery from the laptop, keep it away from your device but place it to the other safe place.
Then Follow this link below:

and start using your laptop normally without the battery plugin but keep the Power cord plugin and internet connection connected.
and you're searching and browsing GMAIL inbox normally will get no alert appears anymore!

I would like to share my marketing activity using my Laptop:
hp EliteBook 2450p, using Ubuntu desktop 20.04.5 LTS.
Opening a lot of multiple tab at the same browser in my daily activity, As a marketer... this is a normal habit,
but most of the time...
We've got a lot of problems with our device,
such as:
> The laptop hang due too many open multiple tab,
> The laptop running effects... very slow,
> The laptop running load average very high then shutdown unexpectedly.
To resolve the problems...
#1. Reduce the overheating.
There are two tools which you can use to reduce overheating
and thus get a better system performance in Ubuntu...
TLP and CPUFREQ.
To install CPUFREQ indicator use the following command:
also...
Restart your computer and use the powersave mode in it.
and looks like this:
#2. Install MSI Fan control within your Gnome Extention
(Edit: Since Jan-2023 I'm not using it anymore...)
Just start using powersave mode only (to reduce the heat rise up)
For your reference:
https://extensions.gnome.org/
#3. update your Ubuntu grub using this configuration: Edited: Thu, May 11, 2023
Save file.
#Tweaking kernel for maximum concurrency.: (Edited on: Thu, May 15, 2023)
Save file.
To make sure it'll be running properly, run this command in terminal:
#4. Maximize Swappiness:
We want to change this swappiness value to 120. (8GB RAM)
To do this,
you will need to edit the sysctl.conf file.
Just enter the following command into the terminal to open the file:
Now find/add the line :
to the bottom of the file.
Save file and You should update the grub.
type in terminal:
Or...
You might be want to use this method (8GB RAM):
regarding vm.swappiness
Let's increase your /swapfile to 4G, and set vm.swappiness to a more appropriate value.
Edit your /etc/fstab, using sudo nano /etc/fstab or sudo -H gedit /etc/fstab or sudo pico /etc/fstab.
Confirm this /swapfile line in /etc/fstab...
and confirm no other “swap” lines... use SPACES in this line... confirm NO TABS...
Save...
Edit /etc/sysctl.conf
Find the line that has vm.swappiness=10 or 20
and set it with:
Save the file. make it sure its running properly straightaway...
update the grub.
type in terminal:
reboot your system, then check your /swapfile
#5. Install Psensors, makes use of lm-sensors and hddtemp to get the temperatures:
and setup preferences and sensor preferences with your device.
#6. MTU Setting
MTU stands for Maximum Transmission Unit and it is basically a parameter that determines the maximum size of data packets
that are allowed to be transferred from the network to your system.
If the MTU value is too small, then you are crippling your speed by dealing with large number of packages, and if it is too large, you are letting the data transmission occupy significant portions of your bandwidth for larger periods of time, essentially causing lag.
So, there is a golden ratio as in everything and if you want to squeeze the maximum performance out of your internet connection,
you can determine and set your MTU to an optimal value.
Open a new terminal session and start ping tests to see what the optimal MTU value is.
Use the following command:
Start with 1480 and drop 10 by 10 until you find the highest value
that is indicating 0% packet loss, using “Ctrl+C” to cancel each ping.
After you have determined the optimal MTU value, go to /etc/network/interfaces:
And add a line “mtu 1470” without quotation marks "..."
(or whatever value you found as the best) and save the file.
Note that you need to open the configuration file as the system administrator
or else you won't be able to save your changes.
#7. Install preload
preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.
Update apt database:
Install preload:
You need to restart/reboot your ubuntu system.
And make sure your esm-infra and Livepatch status are enabled:
For your reference:
https://auth.livepatch.canonical.com/?u ... buntu-user
Your Pro version:
and your pro security-status:
Last but not least... Turn on your air conditioner too, Make it cooler...
Hopefully, this will speed things up a bit without causing network data package errors,
and your daily marketing activity running smoothly as well.
#8. Remove a PPA from the source list in the terminal
For some reasons... You need to remove the PPA from the sources list where these PPAs are stored. PPA repositories are store in the form of PPA_Name.list.
Use the following command to see all the PPAs added in your system:
Look for your desire PPA here and then remove the .list file associated with the PPA using the following command:
The -i option with rm command asks before removing a file. Consider this as a safety check.
Just answer with "Y" or "N".
#9. Open DNS
If you've got problem to reach Google.com or Paypal.com, That's mean your DNS Internet connection is in wrong setting,
Just use the default/auto DNS given from Your Internet Service Network Provider.
Also use the default/auto ROUTER given from Your Internet Network Provider too.
Do not use open DNS such like : 8.8.8.8, 8.8.4.4, 1.1.1.1, 9.9.9.9 within your Device Modem/WiFi/OS (Operating System),
just use: 192.168.1.1 or IP which has given by your ISP.
If your ISP allowing you to use:
First DNS: 8.8.8.8
Secondary DNS: 8.8.4.4
Then there will be no problem when your browser connecting TLS handshake to paypalobjects.com to login to paypal.com or to reach google.com as well.
In case Your connection get an Error event when Connection TLS handshake which result to CSS/Layout/Style web page messed and the links will not connecting/working correctly. (You should contact your ISP or change your ISP Provider)
or
DNS_PROBE_FINISHED_NXDOMAIN
What this error mean?
The DNS_PROBE_FINISHED_NXDOMAIN error means that your DNS setup failed to resolve the address you're trying to open in your browser.
The NXDOMAIN part... refers to Non-Existent Domain, meaning there were issues finding the IP-address for the domain name you requested
Do not mislead...
Open DNS will worked only to used to serve Domain Name System zone for Website Domain within your own Server profile,
and not for Desktop/Laptop Device.
Have take a look... Stable performance! 23 tabs opened at Firefox and Google Chrome Browser in the same time session:

just use: 192.168.1.1 or IP which has given by your ISP.
If your ISP allowing you to use:
First DNS: 8.8.8.8
Secondary DNS: 8.8.4.4
Then there will be no problem when your browser connecting TLS handshake to paypalobjects.com to login to paypal.com or to reach google.com as well.
