Toshiba to market two new notebook computers

Is a 7.2V lithium battery,[link widoczny dla zalogowanych], but the external power adapter voltage is 8.4V, because the lithium battery fully charged voltage of 4.2V. I use the 7.2V Li-ion battery for external power supply, until the battery voltage down to 6V, close to the battery termination voltage can be used normally. If you use a 8.4V battery is better, you can charge the battery to the machine, this method is simple, the maximum battery utilization. 2. Diode depressurization in the current use of silicon diode forward voltage drop to 0.7V by the characteristics of the time, through the calculation, the number of a string of step-down to the rated voltage diode. For example, an external power supply type TRV87E 8.4V, 9.6V battery can be purchased in the battery external power supply line 2 IN5408 diodes in series with the step-down 1.4V, output voltage is 8,2 v. This method is available to machines work simple, the disadvantage is the control voltage accuracy is not high, each block can only be 0.7V, have limitations. 3. Voltage regulator module to buy the battery voltage step-down method to exceed the device rated voltage of 2.5V or more. 5A in the electronic market to buy more than a three-terminal voltage regulator module, the reference price of 5 yuan, because only three joints, the access to the battery input voltage output access list, adjust the potentiometer to the rated voltage can be. For example, equipment can be purchased 10.8V 8.4V lithium battery. Advantages of high precision voltage regulation; drawback is a little complicated, but used to be a small box and aluminum radiators. 4. Optional battery voltage tap method twice for the device voltage, the battery box with a knife forced open, half-tap in the battery, the battery divided into two groups using chloroform and then glue the plastic box, the advantage is the battery capacity doubled, the disadvantage is to be forced open the battery compartment. Specific production methods are: to find a width of 2cm, length slightly larger than the socket terminal of the copper plate,[link widoczny dla zalogowanych], according to the size of the battery slot, notch width and thickness of solder on the appropriate copper (preferably to do tabs, so the battery INSERT), and then welded on the double-stranded power cord. If the machine is a standard jack, you can buy the same model to distinguish between positive and negative plug welding can be used. If the external power jack is not assigned to the private self and difficult, you can plug the original AC power adapter output machine in the appropriate length of the cut line, buy a small two-pin plug with self locking 2, the two were welded into the socket adapter output line and battery power cord, plug wire is welded on the self-locking plug. This plug cable to connect each access to external power adapter and computer use. Charging method: If the battery type consistency, the voltage is consistent with the original machine charger available. If you are not the same, will have to reprovision the charging power supply. Because there are good computer lithium battery charge and discharge protection circuit of rechargeable power source do not ask, higher than the battery charging power supply 4-5V, 1.5A power supply current to pulsating DC. This request can be purchased or home-made products, nickel metal hydride batteries and nickel cadmium batteries almost. Battery charging voltage higher than the number of volts, current to 500mA plug-style rectifier. Laptop batteries for the camera external power supply method is also applicable to other video equipment, such as digital cameras, lights and other power-hungry photographers.

PortegeA100 series CPU to 1.4GHz or more, 12.1-inch screen (resolution 1024 × 768), a stylish pearl white exterior, white keyboard, which stretch across the product compact,[link widoczny dla zalogowanych], stylish performance can be described as a panoramic view. At the same time, exquisite, lightweight design jump full visual experience will be unified in harmony together, and from the \SatelliteM30 series CPU to 1.5GHz or more, is the first launch in the country equipped with widescreen models, it is not only equipped with a 15.4-inch wide-screen LCD (16:10 aspect ratio,[link widoczny dla zalogowanych], a resolution of 1280 × 800 ), but also has exceptional audio performance capability, which can play DVD movies was more impressive. In addition, M30 in size and weight also had the maximum compression (weight 2.8 kg), so eventually the industry dubbed the \Both computers are equipped with wireless, cable networks, USB2.0 interfaces. Is a digital image processing, storage, receiving, transmission is a good helper. (High, editing and proofreading)
