How to find my lost Ubuntu laptop?


Yes, you will be able to find your lost Ubuntu laptop if prey was installed on it beforehand.

Install prey with one of the methods below:

Via the Software Center, click the below button:

Run the below commands in a terminal to install prey,

sudo apt-get install prey

Install from a .deb file.

After installing prey, make an account and you're done.

The free account allows you to use prey on 3 machines. If you need more functions or more machines you need to pay for the pro version of prey.

Prey can only be uninstalled if the thief knows the administrator or super user password. To prevent him from doing so they encourage you to add a BIOS password and disable booting from removable devices on your PC, so that the thief will be forced to boot into the previous installation and thus, not be able to format your hard disk easily.


For any further questions about prey, see: FAQ – Prey.

Background: I'd like to benchmark some SSDs. I am thinking about doing this on my laptop. I would like to check if my laptop supports using multiple SSDs at the same time. I don't want to have to dismantle my laptop to find out, as I currently don't have the tools. I am using an HP Elitebook 8570w.

Question: Is there a linux command that tells how many slots for SSDs my laptop has?

Attempt so far: I've been looking at dmidecode. The command “dmidecode -t 8” seems to give info about sata connectors, and “dmidecode -t 9” seems to give info about PCI connectors, but I couldn't find info on how to interpret the output. It seems like I have 6 SATA connectors and 1 PCI connector, but I am not sure what's being used. Moreover, even if the motherboard has an available connector, is there any guarantee the laptop would have the physical space for the additional SSD?

“dmidecode -t 9” gives:

Ninja Ubuntu Laptop Vanish: How Can I Remotely Undelete?

When I had a bunch of video programs running, as my Ubuntu (operating system) HP dual-core laptop froze, I forced my computer off (via holding on the power button for around 20 seconds until it turned off).

When I turned my laptop back on, my files were gone, my preferences were gone, my operating system (Ubuntu 11.10) was gone and replaced with Ubuntu 10.04, the name of the computer was changed from Joey Arnold's computer to some random numbers and letters, the fiilesystem was different, my previous partitions were gone and replaced with new ones, and my 120 GB hard drive suddenly went from around 15 GBs of free space to around 80 GBs of free space.

I can connect my laptop to my Ubuntu desktop via an ethernet cable wire. I know how to get online from the desktop via the ethernet attached to my laptop, being that my laptop can get wireless internet.

However, I don't know how to remotely undelete. I don't...

I am New to Ubuntu. I'd like to install ubuntu on my laptop. Right now I am using windows-8.1

my drive iis partitioned into 4 parts C:,D:,E:,F:

I want to install ubuntu in C:\ drive without lose of my data on the other drives.

is that possibale... help me


Open disk management in windows and try create unallocated (black) space from other partitons. Boot ubuntu from USB/CD and click Install Ubuntu. If you see "Install Ubuntu alongside Windows 8.1" you can start installing. Windows boot loader will be disabled and replaced with GNU GRUB. You can still boot windows by selecting Windows 8.1 loader


One way to do it is to install it in a Virtual Machine. In that way you will not mess the partitions and put your data in jeopardy. Linux would behave as just another application in Windows.

I would recommend Virtual PC from Microsoft...

Brief: This quick trick shows how to find devices connected to your local network in Linux.

Wireless networks have always been a desirable target for wannabe hackers. Wireless networks are also more vulnerable to hacking than the wired ones.

Forget hacking, do you ever wonder that someone might be leeching off your hard paid wifi network? Maybe a neighbor who once connected to your network and now uses it as his/her own?

It would be a nice to check what devices are on your network. This way you can see if there are some unwanted devices on your network.

So you might end up thinking, “how do I find what devices are connected to my network”?

I’ll show you how to do that in this quick tutorial. Not only it’s a good idea from security point of view, it is also a good little exercise if you have interest in networking.

We will use both command line and GUI way for finding out what devices are connected to your local network in Linux. The process...

There’s one big event that can trigger an overwhelming sense of dread when you’re installing an OS on a friend or family member’s PC: data loss. It’s bad enough when it happens to your own data, but when it’s someone else’s machine, the feeling can be unbearable.

I know because that’s the situation I found myself in during a recent family reunion in upstate New York. I was attempting to install Ubuntu 16.04 alongside a Windows 7 installation on my mother's laptop. And not thinking (I shamefully admit), I failed to make a backup of her data before I resized her Windows partition. It wasn’t until I tried to boot back into Windows 7 that realized what I had done.

After a mild panic attack and several assurances to her that I could fix it, I found the program that saved my butt: TestDisk. TestDisk has been around for a while, and was even reviewed by PCWorld in 2011. It works like a charm, but does so without the aid of a flashy GUI. It turns out it’s in the official...

You may be like me and keep a couple virtual machines around on your laptop for development, testing, and gaming. I had an Ubuntu VM in VMWare that I'd lost the password to, and I wanted to reset it so that I could get back to coding.

Typically, with a desktop computer or a server, you hold down some key while the computer is booting to get into the Grub boot manager and then boot into something called "single user mode", where you're able to change passwords, fix configs, repair disks, etc.

Unfortunately, the boot screen just flies right by in Ubuntu under VMWare. So the first thing you'll need to do is shut down the VM, and then get ready to start it up. But before you start the VM: get ready to hit Shift because that's what will get you into Grub. Ready? Ok. Boot it and hit Shift.

Now you should be in Grub. If you don't get it, don't worry, just shut down and try again.

Choose the 'Advanced Options' and then any of the "recovery" lines from the Grub...

Let’s face it: battery life on Linux is abysmal. If you take a modern laptop running Windows 10, battery life will probably be somewhere around 6 – 10 hours, easy. Install Linux on that same PC, and you’re lucky to get 4-5 hours. Why is this? Well, many Linux developers don’t do enough to help laptop users. Sure, some add a few tweaks, and others even use some of the software covered in this article to help improve battery life on Linux but the majority of mainstream Linux operating systems have mediocre battery life at best.

That’s why in this article, we’ll be going over the best ways to improve battery life on Linux laptops. Let’s get started!


The first piece of software that users can use to improve their battery life on the Linux platform is TLP. It’s a background tool that, once installed, automatically scans the computer it’s on, and adjusts battery usage automatically. For the most part, no tweaks really need to be made with this tool because...

Your laptop computer is probably worth much more than the money paid for it – just think about all the personal folders and files stored on the hard disk and their value to you.

Even if you can afford to replace a lost or stolen laptop – or are able to make a claim on an insurance policy – the missing data could be priceless. Unless you have access to a recent backup, sensitive personal information or treasured digital photos could be gone forever. That’s why it’s always recommended to back everything up on cloud storage such as BT Cloud.

One solution is to install free tracking software that can later be used to locate a lost laptop. If you’re using Windows 10 you can use Microsoft’s existing Find My Device feature, which is explained here. For everyone else, we suggest installing Prey – follow the instructions below to see how it works.

Step 1: Getting started with your free tracking software

To begin, head over to Prey’s website where...

I came from Windows world and always think that if we want to reinstall the windows then we only need to format the C drive while data in other drives survive(e.g. Documents, Software etc.) but if we reinstall the Linux, then all of our data erased(If we used default partition scheme). In this tutorial, I will create separate home partition for my personal data and also want to make sure that it will survive during the clean installation of Linux.

I will use the recommended partition scheme for this tutorial, in which, I’ve created four primary partitions:

1) /boot – for bootloader, if you’re running multiple OS
2) swap – which should be a little larger than the amount of ram you have(double than your ram is recommended)
3) / – the main file system directory for operating system
4)/home – for your data files

Suppose,I purchased a new Laptop and want to install Ubuntu 10.04 LTS on it and for this, I did the partition like this:

In this guide I explain how to disassemble a Compaq Presario v6000 series laptop.

Most likely this guide will work for some other Compaq Presario models.

Let’s take it apart step-by-step.


Turn it off, unplug the AC adapter and remove the battery.

Remove three (yellow) screws securing the power switch cover.

Remove three more (green) screws securing the keyboard.


Start removing the power switch cover as it shown on the picture below.

Be careful, there is a cable under the cover connecting the LED board to the motherboard.

Do not move the cover too far.

That’s the cable I was talking about.


Now you can lift up the keyboard and access the cable connector underneath.

The cable connector has to be unlocked before you pull the cable.


In order to unlock the connector, you’ll have to move the brown...

Linux Thermal Daemon (thermald) is a tool developed by Intel's Open Source Technology Center which monitors and controls the CPU temperature, preventing it from overheating.
Thermald tries to prevent the CPU from overheating without a significant impact on performance

by using some specific Intel functions available in the Linux Kernel. According to the Ubuntu


, thermald can control cooling using:

active or passive cooling devices as presented in sysfs the Running Average Power Limit (RAPL) driver (Sandybridge upwards) the Intel P-state CPU frequency driver (Sandybridge upwards) the CPU freq driver the Intel PowerClamp driver

It's worth mentioning that thermald applies various cooling methods only when the temperature reaches a certain threshold, so you may not notice a difference while using it if your laptop doesn't usually get very hot.

I couldn't find any information on what processors are supported by thermald on its official page, but...

Two months ago, I bought a new battery for my Lenovo laptop (a ThinkPad X230T). I was about to go away on holidays and wanted a battery that could last me through a plane flight; the original battery was by then barely lasting ten minutes. Little did I know that I was about to be in for an adventure.

I installed the new battery, and everything went fine for a few hours… that is, until I had to plug the laptop in to charge. The battery was not charging. Odd. I rebooted, only to find this message displayed on the screen by the BIOS:

The system does not support batteries that are not genuine Lenovo-made or authorized. The system will continue to boot, but may not charge unauthorized batteries.

ATTENTION: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and provides no warranties for failures or damage arising out of their use.

Problem: Wireless USB adapter doesn’t work on Ubuntu. Belkin and Dynamode wireless adapters

Background: Since I can neither afford the luxury of an Apple OS or stand any longer the bloated and slow Windows I thought it was about time to try out Linux on a computer at home. Since the majority of use of this home computer will be browser based (and since soon I believe a great deal of applications will be browser based) I figured that there was nothing to stop me giving it a go.

Well I have to say that once I got the installation complete I was most pleased with myself, and very happy with my zippy new computer.

What you will need
– Your Ubuntu installation CD
– Your windows drivers/hardware drivers cd

It is just fabulous the way that Ubuntu automatically detects all hardware and everything just works automatically – that is – everything except my wireless USB and thus my connection to the internet.
