Most likely, there is a magnet that tells the notebook when the lid is closed. If your phone or mobile device also has a magnet, it can activate it. I know this first hand with my old Blackberry and my MacBook Pro when I first bought it.

Why this happens That prompt is one of the features Windows implements for devices connected as MTP devices. The most sure way to disable it is to connect your Galaxy SII in USB Mass Storage mode. This way, Windows will detect it as a normal flash drive and will transfer files like any other flash drive without caring about the type. Some (desired) more ...

You can use Auto Kindle to convert a PDF to a Mobi file. This project was originally a quick and dirty method for me to convert my ebook collection in various formats to a kindle compatible format without worrying about the ebook source type. It takes PDF, Lit, and HTML files and converts them to .mobi.

I've tried Calibre too; it works, but the GUI too bulky for my simple needs (Calibre provides for library/ebook reader management, allowing you to see your whole library and control which books are synced to which device, including seamlessly converting books to the preferred format for any device along the way). Fortunately Calibre is written in Python, ...

Generally no. Most phones will only charge at 500mA (about half of what a DC charger for a modern smartphone outputs) if it detects it is a USB port. The official standard sets USB 2.0 current levels at 500mA and 3.0 at 950mA. It is not uncommon for USB ports to support 1A or higher though, especially on laptops. The problem lies with the phones. Some ...

For a computer, there is a battery, usually a watch style circular one. This powers a small piece of memory traditionally called CMOS. This memory stores the time and all the other BIOS settings. On a modern PC these batteries tend to last way past the computers useful life time. A mobile phone/tablet isn't likely to have a secondary battery as they would ...

The reason is security. SIM card is not just an ordinary piece of read-only memory. It's a separate micro-computer with its own environment capable of running Java Card applets. They can communicate with network provider and he can modify them over the air to some extent. For example when you want to change network provider, but keep your old phone number, ...

If you are browsing using your operator's network (and not Wi-Fi) they could just check which company owns the IP address that you are assigned when accessing the site. It's pretty easy to do. Click on this to get information about the IP address you are using. As you can see it tells you which company actually uses the IP address in the host section.

Found the solution here. They moved it to "History -> Show Full History". I guess it isn't used very often.

The M215 isn't a Bluetooth device. The M215 uses the Logitech® Advanced 2.4 GHz wireless technology, which is not the same as Bluetooth. Unfortunately, you will not be able to connect your phone unless the dongle also supports Bluetooth. From what I've read, that doesn't appear to be the case. Sorry, you seem to be out of luck.

It won't damage the speaker, but cell phones' electromagnetic fields (emf) can interact with normal speakers. Speakers work with electromagnetism, with an electrically induced magnet vibrating the cone of the speaker to make sound. Cell phones use electromagnetic fields to transmit and receive calls and data. Cell phones may also interfere with other ...

Watch a CRT and then an LCD through a phone camera. That flickering you can see on the CRT but not the LCD is due to the refresh rate and how CRT's work (the wikipedia article briefly talks about it). It makes it much harder for the camera sensor to cleanly pick up what's on screen, since a big dark bar will run through it every few milliseconds.

The USB device should appear under /sys/bus/usb/devices as several entries beginning with 7-6 or something similar. Where the driver link within the directories point will be the name of the module bound to the device.

I would suggest Calibre. It will convert from most ebook formats to most others.

The Tracor Northern image file is a special proprietary format which is not suitable for normal image processing and must be converted to a different format entirely in order to be used by most systems. Programs which use the TN image format generally convert it to a separate and also proprietary IMG format which can be used on MAC and PC computers. The TN ...

In general there is no problem charging your mobile phone over the USB interface of your laptop. Read: ExtremeTech: How USB charging works, or how to avoid blowing up your smartphone I think a usual safety measure is to avoid placing things like passive USB hubs between the laptop and the mobile phone -- particularly, avoid connecting multiple devices on ...

The Oversimplified Principle Of Battery Charging Assuming you know the following: The input power, in Watts, that your power supply / charger is capable of supplying to your laptop The power, in Watts, that your laptop is draining while it is running (assuming you have it running; otherwise this is very close to or equal to 0 Watts) The power, in Watts, ...

I've been trying to find an answer to the question at the top of this page, and so far have not found anyone who has actually measured things. Lots of people say "should" and "might" and "generally" but there is no actual answer. Having the equipment to do so, I did so. I measured the voltage and current coming from my USB power source (more on that ...

Practical Answer "it depends" on how your hold your phone, the layout of the space you're in, how many walls, what's in the walls, etc. Unfortunately, the real-life answer is to just boost the AP power and see if you can connect, and if you can connect some speed-test data to quantify how well you're connected. For example, you may get a useful ...

TCP and HTTP are different things. TCP is the transport layer. By definition, it's responsible for carrying application layer protocols (HTTP in your case) over it. TCP does not run over a port. It is the arbitrator of ports. In other words, when you connect to an HTTP server, you connect on TCP port 80. When you connect to HTTPS, you're connecting ...

If I understand your question correctly, I might rephrase it as, "If the network infrastructure allows HTTP traffic to pass on a certain port, will it also allow pure TCP (without full HTTP-compliant operation or even fake HTTP headers) to pass on that port?" Unfortunately, the answer is, "It depends on details you have not yet discovered regarding how the ...

2,4 is the frequency, b/g/n is the standard. The "best" connection is guaranteed with N because it is the newest standard. This is the IEEE standard 802.11n which supports up to 150Mbit/s!

Portable devices (like phones and media players) do not need, nor can they be, ejected before removing. That's why you won’t see a "Safely Remove" option in the tray menu. You might find this article useful. The relevant information from the article is that Windows gives Portable Devices special treatment. They do not have to be ejected / unmounted. If it ...

Apart from the fact that you need to get your map data somewhere (i.e. over a 3G or WiFi data connection), the current answers miss the most important point: To obtain your precise location. GPS is very precise once it acquires lock on enough satellites. However, more often than not, this takes a while, especially with small receivers or in a city (where ...

An interesting question. Back in the old days we used to have something called an acoustic coupler which did just that. So yes, in theory it could work. In praxis you will run into problems. E.g. the microphone on the phone might distort the sound of your fax. Our your speakers might do that. Or the software in the mobile will drop parts of the audio ...

There appears to be a program called SynCE to allow communication with Windows Mobile, and according to the download and installation page it suggests there are stable versions for most versions of Linux. Hopefully it should be able to achieve what you are after. While looking I did see a program called Multisync, but it looks like it was abandoned in ...

You can use floAt's Mobile Agent. It has a lot of useful features for Sony Ericsson phones and I know it can be used to backup SMS messages, contacts, settings. Maybe it can also save MMS messages.
