A sufficiently satisfactory Surface Pro endurance challenge

Surface consumer attention from the beginning of the listing, Microsoft is close to perfect industrial design on the Surface tablet reflected most vividly. But many friends of Surface equipped with a tablet of the new system will certainly be a variety of doubt, We specially set up the the “Surface Almighty board”, to introduce the Surface the Almighty characteristics and buying guide.

Just landed in the domestic market in the recent Surface Pro is undoubtedly one of the most talked about products in the domestic market, the comprehensiveness of the powerful hardware configuration and Windows 8 systems, many of my friends have a strong intention to buy this product. But also some friends on a product that also raised the question: such a powerful hardware configuration, however, has such a compact body, life is not weak?

Due to the Surface Pro X86 architecture is indeed power is much greater than with the ARM architecture, so a product that certainly in life than to have a large gap in the iPad mini with 8-10 hours of battery life. So I believe that as long as the Surface Pro can have the same endurance (the same hardware specifications) general super pole, is enough to make people satisfied with.

Charging time

With respect to the life time, the charging time is also very important. With the increasing performance of the Tablet PC, the battery capacity is growing, consumers are actually still care about these devices charging time.

We can see from the above figure and the Surface Pro full charging takes about two and a half hours. This data should presumably make the most of the users are satisfied with this than with the same battery capacity of the new iPad shorten the full two hours. Speaking of reasons, Surface Pro power adapter output current is 3.6A, and Retina iPad using the power adapter output current is 2.5A, so the gap will thus produced.

Endurance rival traditional notebook slightly inferior super pole

Microsoft Surface Pro back once familiar x86 architecture platform, so we choose to test software on the PC platform for the endurance test PowerMark it with the famous PCMark, 3DMark, but also by Futuremark company developed. During the test, it will continuously cycle run a set of test scripts, including four common applications: Internet browsing, word processing, video playback, 3D games, as close as possible to the actual usage of the vast majority of users testing.

The test is divided into three, respectively, in Internet browsing, word processing, video playback test three common user options.

Three test test Surface Pro gives the results in about four hours, for a such a high-power products is still a good data. Similar to the traditional laptop, slightly lower than most of the super pole.

Summary:

From Surface Proo hardware configuration and features, its battery life performance is actually completely acceptable. If you have previously used an ordinary laptop, Surface Pro can achieve the same battery life performance, of course, contrast ultra-extreme or slightly inferior, this estimate will be improved in the next generation of Intel Haswell processor listed, look forward to Microsoft Surface Pro 2.

How to Make the Second-hand Laptop Batteries Renewable

For hp 484170-001 battery, a lot of people think is a simple thing, but in the wrong time not know what sample to just can’t find the corresponding accessories, then want to find a the same battery is very difficult or price is not acceptable, then can let a laptop as desktop integration machine used, that is really bad, what method is solved? The answer is yes, in fact all notebook all cell medium but is two kinds, one kind is hydrogen battery, one kind is bedding battery, as long as you have a certain ability (mainly is confidence) so the world there is a rare live you!!!!!!

First of all make sure your notebook is that kind of medium, general has a hp HSTNN-LB11 Batterys hell is a mark, do not know English does not matter, battery case also is but hundreds of words, if there are NI – MH mark (wording), so congratulations you, because you success near some, NI – MH indicate your battery medium is hydrogen battery, you must first make a few battery back, can from the electronic market to purchase or purchase from a “network. This kind of cell shape like home use small battery is almost the same is no outer packing, voltage unity is 1.2 V (if you even 1.2 V is voltage value are not know, so the following article you need not see the) and capacity is not the same, as household battery, small, medium voltage is 1.5 V, but use the same situation as output current the same thing, medium must be small than with a long time. Conditional buy as far as possible capacity big although prices have a certain gap.

The battery, then the next step is to give your hp Pavilion DV7 series Battery surgery, because the battery is “patient” as “the doctor’s you should proceed with caution, the surgery tools is necessary. Provoked the silk knife, pliers, saw blade, lighter, small copper wire, a dc voltage 1 v to 12 v adjustable transformer (small home appliance stores sell), household fuse, electric iron, insulating tape, etc. These things can be bought from the hardware store. Battery shell is mostly by fluctuation two shell from intermediate adhesive and into, then we also from its adhesive place put it saw, (this process the most trouble is successful shut build) slowly saw to do saw into a straight line to aspects of the bonding process, after the test of the ability is also your patience. Saw, pay attention to don’t put battery inside parts saw bad,, anyway as a doctor treat battery is mentality.

Saw opened after you will find inside but is N (sometimes N is more than 10) hp HSTNN-DB75 battery series parallel and er, (good! Yes, in fact, is a few battery series parallel, series is to achieve the standard working voltage, parallel is to achieve a certain battery capacity (namely notebook use time), in fact most cases have a problem not every battery and just one day or a few day, take it out from points need to be wisdom, maintenance process is the only a few questions of the battery shopping away with normal cell substitution off, the question is so simple.

Ok, started to really to do the operation on the hp Pavilion dv6 battery , the battery one section one day dismounting (is the cell of connections between saws, had better be on paper as a draft to avoid memory loss), the battery is points are negative, and battery case connected and smooth side is negative, the other side is positive, the battery function is to store electricity, and discharge. Then verify a battery good and bad is testing its storage and discharge capacity, we give the battery, the operation tools mentioned transformer transferred to 6 v, positive joint battery positive, negative joint battery cathode (this is in overpressure charging), each case 5 minutes stop 5 minutes, the reason is two, one is for transformer cooling, 2 is for battery “rest”. Such operation 8 times or so to complete the store electric process, contrast, discharge test process is simple much more fun, take a day household fuse side joint negative side joint positive (short circuit discharge) if the fuse immediately fuse, then this section is good, and if there is no reaction then this battery is the problem the battery (oh… victory is in sight). So and so the problem of the battery with normal battery instead of, connect again after carefully put it back battery shell, good adhesion after put back to notebook have a try, you will be very pleased.
