HP Touchsmart TX2: Tablet Or Notebook?

Hewlett Packard brings a very interesting model that seamlessly blend the resources of a tablet with the resources of a notebook, the HP Touchsmart TX2 notebook with a surprisingly strong performance. If at first the size of the model causes some discomfort after everything is improved by virtue of its excellent setting that ensures a better performance than others in the category.

For some touchscreen functionality but is not suitable for technology enthusiasts not only impressed by the possibilities that this device features which are many but by the quality of their materials. It has several elaborate details in accordance with design trends becoming very attractive for the same this time. The inspiron 1521 battery has an equally good image quality recording in dark or dimly lit. The wireless has a reasonable level of signal better than other similar equipment.

It is impossible to talk about the HP Touchsmart TX2 without noticing its touchscreen function, it has a digitizer pen which provides a smooth writing on the screen even if we recognize a few millimeters away. It has a side button that corresponds to the right mouse button allowing fast movements. For writing long texts without doubt the best option is the physical keyboard for short messages and the virtual resource works very well.

You can also use the manuscript resource for annotating the notebook. Use with our fingers is a bit different and works in 90% of cases being that the touch is often imprecise. One important thing to note is that even though the hp 484170-001 gets dirty quickly and grease cleaning is easy. Multitouch functionality on the other hand is very welcome and makes the user experience more simple and fun.

If we talk about the keyboard the same even if the computer is small in general this was well developed and ergonomics was intended to provide a soft and gentle touch. If we refer to performance without doubt be a tablet notebook features it has some problems, but if you use programs like Adobe Photoshop can see that we are facing a big machine and therefore a great performance.

Your processor is more than most Core 2 Duo processor and video card attached to it make the difference, which makes the equipment a perfect hybrid. An interesting point is the heating of the team, if we use this game with a potent or powerful design tools can reach ninety degrees but if we give normal use Internet browsing, IM, Skype, Office temperature is stable at the fifty degrees.

In a conclusion the HP Touchsmart TX2 has the advantages of being small and lightweight, the screen rotates 180 degrees and has a great design. As disadvantages we have a touchscreen a little weak and a bad battery.

The First Desktop And Notebook Computers Under The Brand Of Lenovo

March 1st, Lenovo held a press conference dedicated to the Russian market the first products under its own brand. This event, we have been waiting since last September, when it was announced the launch of Lenovo in Russia under the brand IBM Think. Denis Reshin, CEO of Lenovo East Europe / Asia, before the official start of the conference, shared with us some impressions from a recent trip to the Olympic Games in Turin.

Turning to the main part, Denis Reshin said: “The new line, represented in Russia today, is aimed primarily at small and medium businesses, as the most rapidly growing segment of the market.” In the past year, according to a report Gartner Group, small and medium businesses have spent over 400 billion U.S. dollars to buy computers, computer equipment and service support.

A related further reorientation of the policy of the company Lenovo, which until recently has been directed toward the upper price segment, will now be called, first, to optimize the new product to ensure it has even the smallest businesses, without exceeding their budget, and secondly, to capture the new price segments of the market in which the company either did not attend or is insignificant position to date.

In the desktop segment, were presented a series of desktops M, A, E, as well as the recently released 3000 series of light J Series. J Series includes the new J100 and J105, designed for both home users and small and medium businesses. Desktops Lenovo J Series, made in two form-factors Tower or Small Desktop, equipped with light-silver front panel, side vents, as well as additional equipment: block speakers Think Vision USB Soundbar and USB-keyboard Performance USB Keyboard.

Lenovo J100 is made on the chipset SiS 661 supports Pentium 4 or Celeron D; J105, in turn, is equipped with a chipset AMD Socket 745, AMD Sempron processor or AMD Athlon 64. Both desktop models include RAM DDR400 c maximum up to 1GB capacity, equipped with six ports USB, audio jacks, Serial ATA interface and hard disk drive 80, 120 and 160 GB depending on model configuration.

Notebooks submitted C100 series models based on the Pentium M processor or Celeron M chipset Intel 915 GM, performed in an attractive silver casing for a user with a 15-inch widescreen display. With a weight of 2.8 kg Lenovo C100 is equipped with a built-in Wi-Fi adapter that supports three wireless standards 802.11 a / b / g, Bluetooth, as well as 10/100 Ethernet and modem.

The laptop also includes built-in drive DVD / CD / RW or DVD-ROM, at a thickness of 3.3 cm Lenovo C100 is equipped with card reader, four-port USB, FireWire, and slots S-Video, lithium-ion battery provides up to 5 hours.

Take Care Of Notebook Batteries

Take Care Of Notebook Batteries

Cells Lithium Ion battery can be drained or explode if heated to temperatures above 60 degrees, or if they are loaded beyond their power limit. Another problem is that the cells are rapidly oxidized when they are fully discharged, which demands close attention if the battery is completely depleted. To make reliable batteries, all Li-Ion batteries used commercially have some sort of intelligent circuit that monitors the battery charge. This stops charging when the battery voltage reaches a limit and stops the supply when the battery is discharged, in order to avoid discharge.

Another interesting question, especially notebooks, is that the batteries are composed of 3-9 independent cells. The circuit is monitoring the voltage of individual cell, but only the set. This means that in situations where the cells are out of balance, or in cases where a cell is defective premature, the circuit interrupts the power supply after a short time of use. Then come the many cases where a battery that originally lasted 2 hours, 15 minutes passes last, for example.

In most notebooks, the battery circuit works in conjunction with the BIOS of the motherboard, which creates a possibility of various errors. Commonly, after several partial loads, the monitor is out of balance BIOS and go to calculate the capacity of the battery the wrong way. Then whenever you are making partial refills, which will make the battery last less and less, although the cells remain perfectly healthy.

This is why so many notebooks include utilities to “calibrate” the battery, available in the setup. This tool performs a charge and discharge cycle complete, updated measurements. When you leave it unused, Li-ion batteries deteriorate faster when fully loaded or unloaded, therefore, it is best to leave the battery with a 40% load. Heat also speeds up the process, therefore, the colder the environment, the better. A fully charged battery, stored in an oven at 60 C, you may lose more than 40% of its capacity after only 3 months, while a battery retains the 0 C, with 40% load, will lose only 2% after one year.

Avoid discharging the battery when not needed. The best thing is simply to use and charge battery according to its cycle of use. Another tip is that the battery life is less when subjected to fast downloads, so burn DVDs with the notebook using the battery power is not a good idea. Every 20 or 30 cartridges, it is interesting to make a complete cycle of loading and unloading, in order to “calibrate” the measurements of the chip and the BIOS monitor.

At first, removing the battery from a laptop that is connected to making the most of the time would be a good idea to increase its life. The problem is that most notebooks use battery and surge protection from the mains. Removing the battery, this protection is lost, which can shorten equipment life.
