So, I've a HP 4540(H6R10EA) and my bluetooth is working fine under Windows 8.1, but when running Ubuntu 14.04(I've a dual boot) I can't enable it. I tried searching on the forums, but none of the solutions worked for me. I typed in some commands in terminal and the output is down bellow, I hope it helps.
Seems that your Bluetooth driver for your Ralink device (Ralink RT3290) has a bug similar to your problem.
This Ubuntu fourm post seems to have the solution.
I'm not sure on the following because I'm on a mobile device
Hunt around for a readme or similar document, it will give you instructions to install the driver, hopefully
Accidentally I removed Openjdk from Ubuntu. Now it is not possible to install it again.It gives error that:
Use Ubuntu Software Center: OpenJDK Java 6 Runtime
Why do you need openjdk? it's slow and not fully implemented. Use java instead.
Since June of 2017, the traditional way to install the Java 6, does not work. Note that Java 1.6 is not supported anymore by Oracle neither.
The typical method to install Java is adding the webup8 repository and using apt-get to install the software.
A year and a half on, it’s much easier to get a fully-working Linux install on the Asus Transformer T100TA. Remember when nothing really worked, and we had to jump through hoops just to get battery monitoring, or power off working? And wifi was just a pain? How things have changed
Much of the work testing and patching new kernels has been done by Brainwreck and the guys over at the Asus T100 Ubuntu Google+ group. I’ve been away moving house (and job, and country), so sorry for not being around.
I recently did a full reinstall, and here are the latest steps I took to get an almost fully-working machine.
This post refers heavily to the original installation post from 2014. for more detail on any of the steps, you might want to take a look there or in the many helpful comments from other users.
As before, prepare a bootable USB stick, but you can use the Ubuntu 15.10 amd64 release no need for a latest daily build.

The first thing you’ll have to do is to press Esc while starting the laptop to enter the BIOS / UEFI “Aptio Setup Utility”, go to the Boot menu, and change from “Windows” to “Linux” for “OS Slelect” (sic.) option.
If you don’t do that, you’ll only have a cursor on the top left of the display when you boot Linux from the USB flash drive. Save to apply the options, and at next boot your bootable USB flash drive should boot into Ubuntu. If not, press F7 at boot time to access the boot menu shown below.
In my case the flash drive was the first boot device so it started automatically, and after a few seconds, you’ll be asked to try or install Ubuntu.
I’d recommend to just try the first time, and if you can login and connect to WiFi, you can do the actual installation, which I did, and after a few second I got to the graphical installation program asking me to select the language.
So I carried on, connecting to my wireless access point in the process, and selecting US keyboard. I also checked “Download updates while installing Ubuntu” and “Install third-party software…”
Linux Mint and Ubuntu are both known as two of the most newbie-friendly distros around. Ubuntu is the most popular so much so that Linux Mint is based on it. But there are real differences between the two. Which one is right for you?
Linux Mint first hit the scene in 2006. The distro is built on top of Ubuntu but takes extra steps to remove obstacles for newcomers. One key distinction from most other distros is the inclusion of Flash and proprietary codecs out of the box. This will change with the upcoming release, version 18. Then users will have to download codecs during or after installation.
While the numbers are different, Linux Mint releases typically come a few months after each Ubuntu version. Starting with 17, every LTS marks a new version number, with the three subsequent releases being x.1, x.2, and x.3.
