Welcome to a laptop battery specialist
of the Hp laptop battery
Although version 12.04 (Precise Pangolin) seems a long way behind the latest 15.04 (Vivid Vervet) version of Ubuntu, 12.04 is a Long Term Support release. This means it’s guaranteed to get security updates until early 2017 – much longer than standard releases of Ubuntu.
Without delving into chicken/egg debates, if you've ever used Apple's Mac OS X then you’ll find Ubuntu very familiar as there are more than a few design similarities. They're far from the same of course, but it makes for an easier transition if you’re used to Mac OS X. The menu bar runs along the top of the screen, with status icons for battery with such as Hp Pavilion dv2 battery, Hp Pavilion dv2z battery, Hp HSTNN-XB87 battery, Hp NB800AA battery, Hp HSTNN-Q21C battery, Hp HSTNN-IB40 battery, Hp Pavilion dv8100 battery, Hp Pavilion dv8200 battery, Hp Pavilion dv8300 battery, Hp 580029-001 battery, Hp Pavilion DV5000 battery, Hp Pavilion ZE2200 battery, email, Wi-Fi, Bluetooth and time all displayed in the top right-hand corner. Applications sit in a static dock on the left-hand side of the screen.
Hitting the Windows key (yes, there's a Windows key as the Probook 455 G2 is also available with Windows) will open up the search bar. You can search for items on your computer or type in a web address to be opened in Mozilla Firefox, which is the default browser here.
The laptop comes pre-installed with the open-source LibreOffice, which is compatible with the latest Microsoft Office formats. It's less refined than Microsoft's suite, but it’s still more than good enough for most word processing, spreadsheets and presentations tasks, You also get Mozilla Thunderbird, a free email client that integrates itself into the status bar.
One of Ubuntu's most useful features is virtual desktops, or Workplace Switching as Ubuntu insists on calling it. This makes it much easier to multitask on one screen, although this feature has been present in Mac OS X for many years and has finally made it into Windows 10.
The virtual desktops built into those rival operating systems are more elegant though. You can use touchpad gestures, as well as keyboard shortcuts, to switch between different virtual desktops. Oddly, Ubuntu 12.04 is limited to just four virtual desktops in total unless you tinker around with command line settings – a limitation that doesn’t apply to Windows 10, Mac OS X and, to be fair, later versions of Ubuntu..
Ubuntu also has a feature similar to Windows Snap, so you can quickly position two windows side-by-side using either a mouse gesture or keyboard shortcut. It doesn’t work quite as smoothly as Windows Snap, but it’s still very useful to have.
An easy way to find and install more programs is the pre-installed Ubuntu Software Center. While it’s full of video players, email clients, web browsers, games and system configuration tools, it’s more threadbare when it comes to business software. Some basic Access-related tools and utilities are available, but if you want CRM or Visio-compatible diagramming software then cloud-based options are your best bet.
