This is completed on this. If you do not know how to use and for what items in Recovery answers, then read the article

  • If errors occur when installing the update - Status CWM.

That's all! There is nothing complicated! Read more of different articles and instructions in the section. Stay along with the site, then it will be more interesting!

It is possible that few people know that operating system Android generally there is a BIOS, and most do not think at all why it comes there and how can it come in handy. If you treat these people, then it is excellent, in the case of a software failure, it is best to take your device in service center For qualified assistance to the masters. In fact, the tablet is also a minicomputer as a smartphone or stationary PC and there are many similar modules and nodes in it (although they are all solid-state and have their own characteristics). Therefore, many believe that the tablet must be the same programs for starting and identifying equipment. But it is not, because in devices with Android instead of BIOS engineering menu - Recovery, and BIOS is available on Windows tablets.

Log in in Recovery in two ways:

    from the system, in this case, you must make sure that it has this function;

    when the tablet is turned off, i.e. When you press and hold, the shutdown button drops out a menu in which you need to select a reboot in Recovery, in case there is no, turn off the tablet simultaneously pressing the shutdown button and the volume button in the "+" position, while the device will boot into the engineering menu.

It should be remembered:

    first do the first thing backup, since in case something goes wrong, that is, the high probability of data loss;

    in the engineering menu, the tablet sensor will not be active, so all switching between the fields is performed by switching the volume button.

Now it's time to explain why the Recovery engineering menu is needed.

This menu provides several options for updating the system, restoring the tablet, full reset settings.

For system updates Select the first line in the "_update _from" menu, thanks to which all updates.

For system Recovery You must use "Backup _ & _ Restore" and cuts out if you need to restore from backup storage. The manufacturer lays the working image of the system capable of bringing the tablet to the full working condition.

If you go to "Wipe _Data \\ Factory _Reset" item, it will help to perform reset Before installed parameter plants. True remember that when this item is selected, all information will be lost.

And once again back to the fact that they started, if, in fact, it is not known at all about this side of your tablet or you accidentally entered this menu, it is best to get out of it or attribute the device in service centerwhere the wizard without difficulty and the loss of your data will return everything back.

With a laptop, not so simple. Here you sit and break your head, trying to go to the BIOS on Windows 10. There is one secret. We only told our readers, but do not tell anyone about anyone. Go to the BIOS on Windows 10, you can use the F2 keys or DEL. But on the laptops it hinders one small detail: immediately the operating system begins to be loaded. It does not happen on all machines, but it is found quite often. Therefore, it is useless to press F2 or DEL. How to get to the BIOS?

So, the promised trick! You need to log in, and then go to the reboot. Do not help shutdown, hibernation. Need to reboot. Otherwise, do not get into BIOS. And so when the POST test starts again, we will finally see (about 1 second) Invitation (Press F2 to ENTER BIOS Setup). At this time, the F2 and DEL keys are stiguously pumped (and let go). The latter is needed in order not to redo. Because if the OS load starts, then it will be necessary to patiently wait for its end. Then perform everything from the very beginning. This technique allows 100% with confidence to enter Bios even on an unfamiliar laptop.

Stationary PC

Please note that you cannot enter the BIOS if the Ultra option is on quick start. Then the post is folded, the screensaver is cleaned, and immediately the control is transmitted to the Winchestera. And the developers of motherboards assure that it is possible to get out of the situation only in one way - dropping the settings. For this there are two ways:

  1. Pull the battery.
  2. Press the special button (there is far from all cases).

According to our observations, the invitation still sometimes appears. Because we just got rid of our settings.

This is how, apparently, the case is:

  • The board is the start counter.
  • For every tenth, the fifth, nh appears a proposal to enter the menu.

This is a reasonable style, because if you put Ultra Fast, you do not have time to see what the desktop appears before you. So, the setting has been changed without removing the battery and related problems. A dozen uses similar tactics: enough to start the PC to be interrupted 2 times with shutdown system BlockHow the recovery means appears on the third. So, the Reset SETUP is not the only way to log in. Even if the ultrafine launch is configured.

In the remaining cases with a stationary PC there are no problems at all. No need to go to a reboot in a laptop. It will be enough hibernation. When you leave it at least 2-3 seconds, an invitation appears to configure BIOS. The entrance is usually done through DEL (unlike F2 on laptops and ESC on virtual machines). For loyalty, it is possible to press alternately F2 and DEL (if the PC is unfamiliar). And only as a last resort, we carry the battery of settings on motherboardbecause at the same time everything is reset to factory settings. That in many cases is undesirable.

Notebook

It has already been said that the input is easiest to perform after a reboot.

There is a more extravagant method. Take note if it comes up:

  1. Open the laptop housing.
  2. Turn off hard disk.
  3. Willy-Neils PC will be forced to show the input invitation to the BIOS.

It can be used if it does not work otherwise enter the settings. Many are also interested in how to reset the installations on the laptop. The storage principle is the same as before (apparently, this is the most reliable way). Therefore, the solutions are similar:

  • If the battery is available (not the battery, namely the pill), reset through it.
  • Sometimes a special button is served to reset.
  • In some cases, there will be a jumper (jumper between contacts) to implement the desired operation.

Actually, former masters, this is not in a novelty. But it happens when Bios is perepallin. Here you already need the instruction. Create an example for ASER.

Rent translation:

  1. Turn off the power, pull the hard drive, power cord, battery.
  2. Disconnect the cord from the real-time clock battery, find the CMOS jumper at the bottom of the compartment with the RAM memory module.
  3. Close Contacts
  4. Each the power cord from the network (the jumper remains in place), press the power button, wait until test POST. Then remove the jumper.
  5. Reboot the system (without hard drive), press F2 to enter the BIOS.
  6. If the system does not require a password (if it was installed), the settings managed to reset.

It is not difficult to notice that these operations are not under the usual yowser. Why? In order not to have stole information. If the attacker takes a stalled laptop, it will dig for a long time before the data gets. To pull the CMOS battery, you need to work hard and that longer. Here is an exemplary kind of jumper, and do not ask us where to look for the RTC wire (real-time clock). It should be clear that these operations should make a professional by passed by the leadership (Tim.ID.au/laptops/acer/aspire%205732z%205332.pdf).

Tablets

For the tablets, the Android inputs in the recovery menu when loading is simultaneously pressing the power and volume buttons (or up, or down). Then the screensaver appears, from which you can spend all the necessary operations, in particular:

  1. Restart Bootloader.
  2. Start (launch of android without any operations).
  3. Recovery Mode.
  4. POWER OFF.

The flopping of options is made by the Loupe / Hitch keys, select the power button.

On tablets with a dozen, everything is different. You need to connect through a special adapter keyboard to the tablet. And while starting to press ESC. At all, as in virtual machines. That's what it looks like.

To open the BIOS on Windows 10, make the launch and press the ESC before the tenth begin to draw circles from the points.

Virtual machines

On many virtual machines by pressing the ESC, the BIOS is called, but the boot menu (the same as the PC F12). If, of course, enable this option in the settings. But the latter relates to real PCs, and on virtuals this parameter is included by default. It is impossible to change it. The said is illustrated on the screen.

After entering the menu you will see standard set options. Not much different from primitive PCs.

Installation

The inclusion in the BIOS and its switching is the problem itself.

  • Turn on the tablet and press the home button several times.
  • The menu will appear, but only for a short time, you must click one of the volume buttons before it disappears. Pressing the "Home" button at this moment will close this dialogue, so do not press the "Home" button for too long.
  • Select Settings using volume controls, and then click the Screen Lock button to select it. Now BIOS will boot.

Calling the Recovery menu on Android OS

To go directly to menu Bios. And skip the above menu above, it is usually easier to simply hold the "Home" button after pressing the power button until the pop-up menu appears.

To go to the BIOS, at home, the button runs, the lock button is entered, the volume button up and down, and the volume buttons and the lock button are simultaneously held left and right.

Use it to enable Legacy USB. This allowed me to use a USB keyboard and gave me the opportunity to boot from USB. From here your classic ARCH installation. (Installation Instructions)

net

wireless

The wireless chip works out of the box, both with network and network manager. However, if you place the network manager daemon before Display Manager, if you have, it can sometimes turn off the wireless connection.

bluetooth

Just install Bluez and any front end (or his absence) that you like. Enable when started using SystemD by startup

Buttons

Volume buttons and power button, apparently recognized by default. Like rotation lock and home buttons do not work.

Click the lock button and the "Home" button, then run

You must get such a conclusion

See the following article, setKeycodes, how to configure these 2 keys.

In addition to this article, before starting SetKeycodes you can easily check whether the key you are about to install, already running

where ### is your desired key code.

It is also worth noting that if you want to use it for quick access In GNOME, you need to try several different keys, as it is easy to choose a value that GNOME will not allow, as this may be a letter to a foreign alphabet or similar. GNOME also seems to not allow you to use a value that is not configured to anything, so you basically need to find some really unclear keys for use.

As a result, I went for 167 (Audio Record) and 171 (Tools)

Graphics

The XF86-Video-Intel driver works well without the need to configure.

The brightness most easily changes using the ACPI method described in detail on the backlight page # ACPI.

Touch screen

The touch screen works out of the XF86-INPUT-EVDEV box, and the pen works almost excellent with XF86-INPUT-WACOM.

To force the Feer button to emulate the right click, go to the Wacom settings in the system settings.

The touch screen will be recognized as a finger input by many applications, such as Gnome Files or Chromium by default, and will drag to the scrolling page, and not to the selection of text or objects.

Screen rotation

If you like to use a tablet in portrait mode or any other orientation than normal. Simple screen rotation control is not enough, as the inputs touchscreen And Wacom will still be calibrated in standard landscape mode.

The touch screen is calibrated by inversion of axes and replace the axes. Moving axes basically means that the X axis becomes Y and vice versa. The inverting axis is folded up and down or left and right.

However, the Wacom tablet simply uses the number, 0, 1, 2 or 3, but they do not correspond to the XRANDR numbers.

For non-permanent turns there is a simple scenario SH. Download Slate.sh.

To rotate to a specific XRANDR position

Rotate the Click button (GNOME)

You can configure the screen rotation when you press the key combination, or the side buttons if you set them the buttons above [Disabled Reference: Invoice section]. Go to System Settings\u003e Keypad\u003e Labels\u003e Custom Labels Click "Add" and Under commands Add the path to Slate.sh -r. For example:

Then add. Now you can install a shortcut by clicking on it and pressing the desired keys.

Multitach

The 8-point multitouch now seems to work without an XF86-INPUT-EVDEV-MultiTouch Git Aur [non-working link: archived to AUR-Mirror], and MTDEV is the dependence of XF86-INPUT-EVDEV. The delivery of GNOME 3.14 includes applications such as Eye of Gnome (GNOME Image Viewer) supporting multitouch actions such as Pinch-to-Zoom.

I also installed Ginn Aur and all Utouch Ubuntu (depending on GINN). The default setting gave me a scrolling of 2 fingers in all applications that I tested.

You can test Multitach, running MtView-Git AUR:

It is worth noting that the theory should have 10 fingers Multi-Touch, however, since you can hardly put 10 fingers on the screen, this is not a problem.

Accelerometer / MageNetometer.

Slate series 7, as far as I can judge, uses an accelerometer / magnetometer STMicroelectronics LSM303DLH. Currently, I'm trying to run it. As soon as I do this, I will send instructions on the LSM303DLH page.

sound

After installing the GNOME, the sound works without any additional features. Rocker buttons on the side also work without problems.

Webcam

To force the webcam to work, Gstreamer0.10-Bad-plugins AUR or similar.

accessories

I did not have problems with the docking station. It seems he works as expected.

keyboard

However, there are instructions for setting up the Bluetooth keyboard, however, if you have GNOME installed, run "System Settings"\u003e Bluetooth. Make sure the Bluetooth is turned on. Now press and hold the power button on the keyboard until the LED flashes.

Return to the Bluetooth window on the tablet, press the + button below the device list. It will guide you through the wizard that will twist the keyboard for you. When it gives the code, simply enter it on the keyboard and press ENTER.

Articles and Lifehaki

BIOS - softwarewhich sets all low-level settings for your computer. And those who only recently moved from PC to the tablet, often wondering, and how to enter the BIOS on the tablet.

I immediately want to say that there are no bios on tablet computers, except for those that work on the operating room windows system. The rest have only modes that imitate the work of this software. For example, android is a recovery, IOS is DFU.

Where is bios

After calling the main menu on the gadget display, you must do the following to find how to get into system software:
  1. Go to "Settings".
  2. At the bottom there will be a string "change parameters", you need to click on it.
  3. On the left will pop up the menu where you only need the lowest line "Update and Recovery", click on it.
  4. Now you will see a small list of features, select the "Restore" section.
  5. Right click on "Restart Now".
  6. The tablet will begin to reboot, after which the "Select Action" menu appears, while the color of the display will be blue.
  7. Here choose the "Diagnostics" item, and in it - "additional parameters".
  8. After multiple icons appear with different system features, select "UEFI built-in parameters.
  9. Click "Restart".
  10. When the device turns on again, you will automatically find yourself in the BIOS.

How to enter bios via keys


Also open the system software using keys located on the housing tablet computer With Windows. For this:
  • Press the volume buttons and turn on the device.
  • Hold them for four to five seconds.
  • As soon as you enter the BIOS, the keys can be released.
Thus, you can start working with a tablet computer system.
