HP Mini 5102 Laptop Screen and Speakers

The 10.1-inch screen on the Mini 5102 is a nice LED-backlit display panel with a 1024x600 native resolution. The matte screen surface is a welcome change compared to the glossy screens we usually see in netbooks. The matte surface helps to prevent glare and reflection on the surface of the screen under bright indoor lights and helps improve sunlight readability. Despite the nice matte screen surface, we really wish the 5102 used an 11.6-inch screen and 1366x768 resolution seen on many modern netbooks. A resolution of 1024x600 is okay in a pinch, but many websites just don't look right without a minimum vertical resolution of 768 pixels. On that note, HP includes at least some software optimized for lower-resolution screens. Corel Home Office (compatible with Microsoft Office) comes pre-loaded with this netbook and the Corel software looks much better than using Microsoft Word or PowerPoint on the tiny screen.

Vertical viewing angles are average with some color distortion when viewing from below and some over-exposed colors when viewed from above. Horizontal viewing angles are better with colors remaining unchanged at extremely wide viewing angles; you won't have trouble sharing a YouTube video with friends using this display.

The built-in speaker performance on the Mini 5102 is good for a 10-inch netbook but it's obviously weaker than a typical 14-inch or 15-inch notebook PC. I'm not a fan of the location of the built-in speakers since they're located on the bottom front edge of the netbook, but the audio quality doesn't suffer from any distortion issues until you get to maximum volume levels. The speakers lack much bass, but the range of highs and midtones are perfectly enjoyable. Again, the only major problem I had with the speakers is that they sound muffled if you use the netbook on your lap.

Granted, most audiophiles will want to use external speakers or headphones for a better listening experience ... but the built-in speakers work well in a pinch. The audio output from the headphone jack produced some high frequency background noise/distortion with one of the headphones we used during testing, but other headphones worked fine with no distortion.

The Guide of purchasing a Solar Charger

Nowadays, as the developed of the solar energy, the solar products has gone into the household, such as the solar water-hearter, solar chargers and so on, today we will talk about the guide of purchasing a solar charger, help you choose a good solar charger for cell phone, tablet, ipad, iphone and laptop.

The solar charger is good or bad, have four key points:

1. The using Efficiency.

Using efficiency include two ways, The conversion efficiency of the solar panel, and the secondary conversion efficiency. The conversion efficiency of the solar panel, As the name suggests is the efficiency of conversion of light energy into electrical energy, and the secondary conversion efficiency is the efficiency of light energy into electrical energy stored in the battery.

2. The quality and the capacity of the battery.

The capacity of the battery inside the solar charger must be 1.2 times or higher than your products, only this can full charged your products, because there will be energy losses in the energy conversion process, the conversion rate is generally 80% -90%. And the quality of the battery is related to the solar charger’s using life.

3. The control circuit and the protection circuit

Solar mobile phone charger products in the market is very complex, It's protection circuit and control circuit may be a simple design, or in poor compatibility, it is very easy to charge bad the phone or shorten the phone and battery’s using life. Therefore, the design of the control and protection circuits are very important.

4. The accessories of Solar Charger

This is a problem that many users may ignore, but it is a point that should not be ignored. There are many bad suppliers on the market for price advantage and configure inferior accessories, such as the AC Charger, the AC Charger can divided into with IC protection circuit and without IC protection circuit these two kinds, the AC Charger without IC protection circuit not only little charging current, long charging time, bad charging effect, but also have security risks, so when you are choosing a solar charger, you should pay more attention to whether the AC Charger has IC protection circuit or not.

Solar cell phone charger can only be used in an emergency, you can not completely rely on it to charge mobile phones and other digital products, generally speaking, to full charge the cell phone, the Solar Charger of Cell Phone solar panels must more than 0.7W.

"Nano-flowers" are made up of the dust of germanium metal sulfide, and sulfide Germanium is a semiconductor material, it is Petal-like, although the object is very small, but the surface area is very large, so it can store a lot of energy.

The structure of this nano-objects is made ​​by scientists from North Carolina State University and his colleagues. They poured the Metal dust into the melting pot, till gasification, and then blown to the relatively low temperature of the furnace area, the dust Solidify into a layers of sheet, These "petals" shaped sheets have only 20 to 30 nanometers thick, and not longer than 100 nanometers.

The researchers said that due to the small thickness, larger surface area, the flower-like structure is expected to improve the capacity of lithium battery.

The basic information of Solar Charger

Solar charger is a device that can convert solar energy into electrical energy stored in a battery inside, the battery can be for any form of power storage devices, mainly are lead-acid batteries, lithium batteries, nickel metal hydride battery, and the load can be mobile phones and other digital products, the load is diversity.

The Product Type of Solar Charger

Type one, with lighting function’s solar charger, built-in super energy-efficient LED lighting lamps, very power. If simply used for LED lighting, according to the size of the built-in battery capacity can be used for 3 hours to 30 hours.

Type two, only with charging function’s solar charger, this charger without any other extended features. The advantage of this type of charger is the capacity is very large, very suitable for professional external power supply.

Type three, support power adjustable block’s solar charger. General Support 5v, 9v can be adjusted.

Solar panels

Nowadays, the Market-oriented conversion rate of solar panels is still relatively low, generally have only 16.5%, some have 17%, and someone abroad have done by 25%.

U.S. researchers at Rensselaer Polytechnic Institute in 2008 have develop a new type of coating, covered this coating in solar panels can make the the sun absorption rate increased to 96.2%, while the sun absorption rate for ordinary solar panels have only about 70%.

The new coating is mainly to solve two technical problems, one is to help solar panels absorb almost all of the solar spectrum, the other one is to make the solar panels absorb the sunlight from a larger angle, thereby enhancing the solar panels absorb sunlight efficiency.

Ordinary solar panels typically only absorb part of the solar spectrum, and usually when only absorb direct sunlight the work efficiency is high, so a lot of solar installations are all equipped with automatic adjustment system to ensure that the solar panels is always to keep the sun most conducive to absorptionthe angle of energy.

The battery of Solar Charger for Cell Phone are usually lithium battery, the best should be the lithium polymer battery, security and high-performance

The principle of the solar cell phone charger is converted the solar energy to electrical energy stored in the built-in battery of solar cell phone charger, when need to charge their cell phones, solar cell phone charger battery will output the energy to charge the phone.

Applications, this kind of solar charger can be used for cell phone, digital camera, PDA, MP3, MP4, tablet PC and other digital products.

External Battery and its Cells

External Battery also be called mobile power. With the popularity of various smart phones and tablet pcs, More and more people find all kinds of digital products, particularly the power of the cell phone itself has been unable to meet our daily use of the life time. And the emergence of the external battery can solve this problem to some extent. So to those who do not come into contact with the mobile power consumers, how to choose the array of mobile power ?

Good external battery, the key we have to see is the battery’s cells. The internal cells of mobile power just like a car's fuel tank and transmission system, responsible for providing endless power for the entire mobile power, Directly determine the external battery is good or bad. The board of external battery can be seen as a control system, is mainly used to be responsible for power distribution and conversion, convert the 3.7V lithium batteries (or higher) voltage into the standard 5V (or higher) voltage, supply power to the devices that need to be charged.

The current external batteries generally use the lithium-ion battery, but the performance is varies, we can not distinguish from their sharp, and the general specifications label also can not reflect. Now Let's start from the batteries, step by step, to explore the mysterious world of mobile power.

The lithium-ion battery, depending on the different electrolyte material used, can be divided into two categories of liquid lithium ion battery (LIB) and lithium ion polymer batteries (LIP). Both LIB and LIP ‘s positive and negative material is the same, cathode materials for lithium cobalt oxide, nickel cobalt manganese and lithium iron phosphate material these three kinds, and the extremely negative is graphite, their working principle is basically the same.

Their main difference is the electrolytes, the liquid state lithium ion battery using a liquid electrolyte, and the lithium ion polymer batteries use the solid polymer electrolyte instead, Such polymers may be a "dry state", and may be a "colloidal", present, most use the polymer gel electrolyte.

The Classification of External Battery

According to the different of battery cells, we can divided externalbattery into two species, one is the original lithium batteries, another one is polymer batteries. There are big difference in the material composition and shape between them.

1. Original lithium batteries

The advantage of ordinary lithium cell battery, Because of the relatively long development time, the price of the battery is very low. The disadvantage are, there are many waste refurbished battery, because of the process causes, the problem rate and failure rate are high during producing. Institutional, heavy weight, short life and may cause an explosion. The mainstream mobile power phasing out of such cells. In the coming days, the ordinary lithium batteries will gradually withdraw from the stage of history.

2. Polymer batteries

According to the Electrolyte materials used in lithium-ion battery, lithium ion battery can be divided into liquid lithium-ion battery (abbreviation LIB) and polymer lithium ion battery (abbreviation LIP), the Positive and negative materials used in polymer lithium-ion batteries is the same as used in the liquid lithium-ion battery, Cathode material can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials and lithium iron phosphate materials, Extremely negative is graphite. The battery’s working Principle also consistent, The main difference between them is the electrolytes different, the liquid lithium ion battery use the liquid electrolyte, and lithium ion polymer batteries use the solid polymer electrolyte instead, Such polymers can be a "solid state", can also be "colloidal state", most of them use the polymer gel electrolyte present.

The detailed introduction of External Battery

External Battery, also called mobile power, mobile battery, backup battery, The concept of “ External Battery “ is development with the popularity of digital products’ rapid growth, its definition is convenient and easy to carry large-capacity portable power supply.

Now, the digital products function is Increasingly diversified, and the use of them is more frequent, it has more and more closely associated with our daily life, the importance of How to increase the use time of the digital products, to play its most important function is even more urgent. ExternalBattery, is the best solution to solve this problem, Carry a mobile power can be achieved mobile charging to a variety of digital products in anywhere outdoor.

Working Principle

External battery is a portable device that a set of electrical storage, boost, charge management, Storage dielectric generally use lithium batteries, because of the relatively small volume of lithium batteries, large capacity, wide market liquidity, affordable, widely used in digital products. The voltage of lithium batteries is between 2.7V – 4.2V, the voltage decreased with the decline in electricity consumption, and Voltage of 2.7-4.2V can not directly charge the other digital products, Because digital products lithium voltage is also 2.7-4.2V, the voltage between the same potential can not be charged. So the output power of the mobile power must have a boost system, boost the 2.7 – 4.2V voltage to 5V, so that it can charge to other digital products, such as cell phone, MP4, tablet pc, psp and so on. Of course, the mobile power is not a one-time equipment, it can be used repeatedly hundreds of times over. So when the mobile power is used up, we must charge the external battery, The principle is the same with charge the cellphone, Connected to 5V USB computer interface or USB charger cancharge mobile power. So the external battery must also have a charge management system, the charge management system can automatically adjusts the charge current based on the voltage of the lithium batteries, the Process have pre-charge, constant voltage charging, and Float charging, etc..

Sony will also enter the Windows Phone market

Sony mobile, the UK and Ireland general manager Pierre Perron in IFA general meeting told reporters: "Sony's strategy is very open, Microsoft has always been our partners. Although android is our preferred partner, but Sony is clearly not only select the single partner. Now we are in talks with Microsoft, hope to make our products more diversified. "

Pierre Perron pointed out that in the upcoming marketing activities, sony will highlight the integration of Sony mobile phones, tablet PCs and TV. Such as achieve the shares of pictures and photos through two devices that support NFC, without the use of Bluetooth or Wi-Fi. This will become a selling point of the Sony Windows Phone 8 and Windows8 equipment.

It seems that sony has a great change in the attitude to Windows Phone, the CEO of Sony Ericsson ever said that “invest money to a platform that is not better than the current system will made ​​me feel uncomfortable, so we will continue to adopt the Android system, although I am curious to Windows Phone.

The restore method of Laptop Battery Loss

Many people often complain that their laptop’s using time is short, or aften using a certain time, the laptop using time get short, this is because of the laptop battery loss, and is there any method that can restore the laptop battery. Now introduce what is the laptop battery loss and how to restore the laptop battery, make the laptop using time get longer.

Laptop Battery Loss

Any battery (including notebooks’) will have a design capacity, such as: 4800mAh, 23Wh, these are the maximum capacity representation, In fact, the actual capacity did not reach so high, or after a certain period of time will become smaller and smaller, such as: the label on the battery is 4800mAh, but actually, only 4500mAh, then this difference between them is battery loss = (4800-4500) / 48,00*100% = 6.25%. There is a variety of reasons can cause the Laptop Battery Loss, so we should avoid the occurrence of the following circumstances as soon as possible:

1. The poor quality of the battery itself, the battery loss increases after using a period of time.

2. The charger is not good, its charging voltage and current can not reach the battery charging requirements.

3. Using the laptop in high or low temperature environment for a long time, also will cause the battery loss increases.

4. Most batteries has remaining power protection, it will start protection after the battery power is less than 3%, but sometimes the users charge the battery after the battery is full discharged, this is not correct.

5. Frequently not fully charge and discharge, the battery did not run out and charge it as they like, which will also caused the battery loss.

6. Not standardized mating battery, or long-term use the battery in the very moist conditions, and long-term use the power in the electromagnetic radiation (leading to a conductive metal in the battery)

The restore method of Laptop Battery Loss

The most common notebook battery loss repair method is charge and discharge notebooks, we can use the external software monitor battery loss. The battery have a certain of loss is normal, new laptop should not use, now introduce how to restore the battery loss through charge and discharge.

The easiest way, Open My Computer - Control Panel - Power Schemes, choose all time parameters using Power Options selected as "never" and "alert" option untick. Unplug the laptop power cord, and stay the laptop to automatically shut down, (in this process, do not let the machine standby); repeated for three times like this, allows notebook greatest degree ofrepairing batteries loss.
