Tuesday 17 November 2009 - laptop battery recharge time
Laptop battery rumors 6: laptop battery recharge time is generally controlled, for the laptop battery is full then, while continuing to charge the battery charge 1 to 2 hours, which would help to enhance battery saturation.
Truth: In fact, today's laptop battery usually had a power protection circuit, full power after the battery protection circuit will automatically cut off the charging circuit. Therefore, the laptop battery charge time is a fixed value, filled with the battery after the power supply only for laptop devices, even if the battery charge for 12 hours and then it is useless.
The classification and distinction between the battery
In general we use there are three kinds of batteries, 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI, in recent years, In the notebook field has also been a fuel cell, its only by-product of water and heat, no noise, the basic pollution-free, efficient power generation systems in general higher than the multi-reach 43 ~ 58%, if the heat produced by the reaction utilization, efficiency can be up to 80%! Is a clean and environmentally friendly power. Because of its technology was not perfect, there are still many problems to be solved, and now it is in terms of cost, size, weight, ease of access to fuel, both absolutely can not and traditional lithium batteries and polymer lithium battery to compete.

Tuesday 17 November 2009 - To do HP DV6000 Battery
To do HP DV6000 Battery, use an external power supply when the AC is best to unplug the battery, or battery life if exposed to heat their impact on the state. If the long-term without the battery, please charge and discharge at least once a month to ensure that its activity. In the custody of the battery when there is a need for attention. At present, the vast majority of notebooks used in lithium-ion batteries do not use if a long time, often prone to the phenomenon of excessive discharge, may no longer be able to charge. In order to prevent over-discharge, can be in semi-charged state to save in a cool dry place, and then every six months, and then to half of its electricity charge state.

Friday 13 November 2009 - Toshiba Laptop Battery capacity
After the current correction Toshiba Laptop Battery capacity is also unable to meet the operational needs of the brother, this brother hastily asked me how to do? The author gives the following two solutions:
The best way is to replace the Toshiba laptop batteries. Original purchase of a Toshiba laptop battery manufacturers, you can get a better draft renewal time. But at the moment are all original standard Toshiba laptop batteries expensive, if the economy does not nervous, I still recommend including the owner, including a friend purchase. There is also a kind friend for the Toshiba laptops have greater demands on battery life, but the economy was well-off, I suggest you can purchase a long-term expansion of the main battery or the battery. Of course, this method is the most expensive and, in particular, is to extend the battery is often due to less production, the price is the most expensive of the three types of batteries.

Thursday 12 November 2009 - Battery Capacity
(5) Battery Capacity
Battery capacity refers to the amount of electricity from the battery to obtain, often C, said the unit, said common Ah or mAh. Capacity is an important indicator of electrical properties of the battery. The battery capacity is usually divided into theoretical capacity, practical capacity and rated capacity.
The capacity of the battery capacity of the decision by the electrodes, if the electrode capacity varies depending on the capacity of the battery capacity that smaller electrodes, but by no means the sum of positive and negative capacities.

Thursday 12 November 2009 - the first charge and discharge battery
When the first charge and discharge battery currents must be small (but not too small, or too long), there is to try to be filled, put completely.
I realize the method is that, when the current size of the charge transfer can not be basically,
If it is random on the filling, then do not choose fast charge mode bar (express charge mode), because the battery in use after a period of time has been a bit of aging, and
Concrete expression of the resistance is bigger, in charge when the voltage across more than rising, fast and so easy to think that the charge control circuit is already full, and
Capacity is also naturally be "down" (in fact, there can not be recharged into the electric).
Discharge is the discharge current as small as possible, the operation is slow the first CPU, hard disk stops turn, transferred the darkest the screen (or close the switch off), then is not to run any program,

Laptop battery loud noise with a lasting
A first-come take a look at from the perspective of energy-saving laptop battery, since you want to use a little longer, then the
It is necessary to first know how to avoid cell "aging"! Usually, due to battery internal resistance with the use of time constantly growing larger, there will be a substantial voltage drop in system voltage support is not sufficient, resulting in a serious shortage of electricity. Over time it will form a vicious circle, seriously affect the battery life books. This is fortunate, and sometimes the battery of your books will be in a very short period of time expired, and was very nerve-racking! This failure is probably caused by batteries, but found mostly in lithium batteries, in fact, books like household flashlight battery, as is a composition of one of the batteries, as long as one of a failure of the , then it will result in the overall series,

Thursday 12 November 2009 - To reduce the battery volume
To reduce the battery volume to extend the use of time at the same time, increasing frequency of use to reduce the memory effect of the negative impact of such purposes, taking into account the cost of the battery and the use of the safety, the battery continuously refined in the selection. With lithium-ion battery cathode material, for example, the current can be broken out of lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, and many other raw materials. From a technical perspective, the current lithium cobalt oxide-based batteries. To further enhance the product's energy reserves, a higher technical level lithium nickel material is expected to enter the market in 2000. However, as battery cathode materials have limited impact on their properties, according to experts estimate that by 2000, the volume of lithium-ion battery energy density of about 400wh / l, while the minimum thickness of a single batteries should be 4 ~ 5mm between the in performance is almost there is not much room for development.

The internal structure of notebook computer Laptop Battery
Talk about what constitutes a core component of notebook computer batteries battery pack. General laptop battery is 10.8V or 11.1V, and a single cell can not meet the requirements of notebook PC batteries and are based on so many single cells in series and parallel component of the battery pack (pictured is the use of two sets of three parallel series, after The composition of the battery group). As we often see in the battery shell of 3300mAh, 4400mAh and so refers to the capacity of the battery, which is indicative of the current on the battery discharge can be used for one hour, for example: 4400mAh lithium battery can be a 4400mA discharge current hours. Therefore, the value the bigger the better to prove it can work longer.

Wednesday 11 November 2009 - Hp EV089AA battery not connected
Preferably Hp EV089AA battery not connected to any peripherals, try not to use the CD-ROM, floppy drive, we recommend the use of notebook that comes with the mouse or the touchpad bar (with the mouse is ... ...), LCD screen brightness should be appropriate to reduce, so that can also reduce some power. "
It seems, in order to extend the battery usage time is also required "careful planning." Is estimated that the nominal battery standby time, the actual notebook manufacturers are measured out by the above method. I also have a practical use in the discovery, that is WIN2000 more energy efficient than WIN98/ME some, in my notebook, for example, without any operation, hard drives and LCD screens do not close the case, the standby time is running WIN2000 2 hours 43 minutes, WINME standby time is 2 hours 31 minutes. This is just a little bit of my feelings, only for your reference

Tuesday 10 November 2009 - fault type:Hp DC359A Adapter -free output
fault type:Hp DC359A Adapter -free output
Such is the most common failures, mainly for the AC Adapter supply does not work. The host to confirm the AC Adapter cord is connected to a good (some with AC switching AC Adapter supply to hit the open state) circumstances, the boot no response, the display no display (monitor light flashing). Fault-free output is further divided into the following categories:
‡@ +5 VSB no output
+5 VSB has been mentioned earlier in the host received an AC AC Adapter supply that there should be a normal 5V output, and for the board to start circuitry. Therefore, +5 VSB no output, the circuit board can not start the action, will not boot.
This failure to develop methods are: the AC Adapter removed from the host, then a good host AC input AC Adapter lines, AC Adapter output measured with the multimeter to the motherboard 20-pin plug in the purple line (+5 VSB) the voltage, without the output voltage is illustrated in +5 VSB line has been damaged, in need of replacement AC Adapter. For some motherboards with a standby light, no meter, you can also use indicator light to determine whether or whether there is +5 VSB output. Such failures show the AC Adapter within the device is damaged, the insurance is likely to have been fused.

Tuesday 10 November 2009 - Dell laptop power adapter is called Dell notebook computer's "power source",
Dell laptop power adapter is called Dell notebook computer's "power source", many users tend to focus only on the maintenance of mainframe computer Dell laptop, but very few people will take into account the maintenance of Dell laptop power adapter. In fact, Dell laptop power adapter has been working in high-voltage, high current state, the internal temperature is high, so in their daily use, if not pay attention to its proper maintenance and maintenance, Dell laptop power adapter is more likely to damage high.
Dell laptop power adapter is a high-precision, high-efficiency switching-type regulated power supply, its role is to 220V of AC electricity is converted to low-voltage DC (typically 16V ~ 19V), for the Dell notebook computers to provide a stable work of electricity.
As the Dell laptop power adapter is a work in-house high-voltage, high current state of the switching power supply, work load more weight (usually for Dell notebooks 50W ~ 100W power supply output power), and is completely closed structure, case there is no cooling holes, the internal nor the fan-assisted cooling, so Dell laptop power adapter at work, the internal temperature is high. Especially in the hot summer, touching the surface can feel the hot, the internal temperature is even higher. Thus, in daily use, we should pay special attention to the heat Dell laptop power adapter, and other maintenance issues.

Tuesday 10 November 2009 - a simple Dell Inspiron E1505 keyboard fault handling
Another button is invalid or double-click the mouse frequently asked questions are also insensitive, frequency of use left mouse to be much higher than the right, so the button is most likely to first failure, If you want to improvise a temporary period of time, you can enter "My computers, "" Control Panel "," mouse "," button ", is set to" left hand used to "can make the right mouse button into a left and continue to use. Double-click the insensitivity were mostly related to inappropriate and double-click speed settings, the same access to "Control Panel", "mouse", "button", where you can adjust the double-click speed settings and test the adjustment of the results. Generally speaking, for the novice computer users, it is best to adjust this rate was lower.
Third, a simple Dell Inspiron E1505 keyboard fault handling
Mouse maintenance is simpler, more than 90% of the fault for the break, keys being exposed, mechanical (optical) system caused by dirty, a few low-quality products and components are often cold solder joint damage, including damage to light-emitting diode component aging, crystal, IC damage to the most common. Disconnection fault occurs in multi-connector plug, or bend at the mouse, showing the cursor does not move or the good times and bad, hand to promote connection, the cursor jitter. Failures as long as not appear in the PS / 2 plug Kou Department, the general is not difficult to handle, cut the re-welding can be. Button failure, manifested as a normal cursor, but the buttons do not move. Under the original mouse can be welded, apart of the micro-switch, carefully clean contact, wiping the grease, the majority could be restored after a good install. Hodge-poor mouse button failures mostly reed fracture, treatment is only to be replaced (or will be left up to the right reed for use).

Tuesday 10 November 2009 - To minimize the battery discharge
To minimize the battery discharge less than the charge or over discharge
In fact, over-discharge well resolved, and not to terminate the discharge limits can be set too low, and I have been using 3%.
Very often, the battery may be just a short time, such as the battery remaining 70%, if the switching power supply, then the battery will automatically charge, there is no such a cycle, although battery life is not to set the absolute number of cycles of death, But always it will reduce the battery capacity, lithium-ion battery is alleged that no memory effect, but in fact only a relatively low memory effect Bale. Unfortunately, IBM does not provide solutions to less than the charge-discharge method, but provides a basis for solving this problem. This is what I found on the R31 may not necessarily suitable for other machines, but the method should also be not far off, do not forget, after you tried to paste them all to share.
R31 charging circuit based on the status of the power to decide whether to charge the battery. Power supply output voltage is 16V, within the margin of error of plus or minus 0.2V, if the voltage is below 15.5V, then the charging circuit is not charging the battery, while the books still work, that is, IBM provides the basis for settlement. However, this foundation is weak, because if the voltage below 15.2V, books will be converted to use battery-powered, even if the power supply plugged into the books are useless. In other words, we can toss the space is 0.3V.

Monday 9 November 2009 - using the battery-powered
the less frequently used device is disabled. Usually when using the battery-powered best to temporarily disable the swap the unwanted interfaces, such as wireless network card, printer port, infrared port, 1394 Firewire port, etc., or would waste a lot of battery power, the specific method is in the " Control Panel "-" System "-" hardware "-" Device Manager "to find their own want to disable the device, and then click on" disabled "can be, and need to use the time to be" enabled devices ", is very simple. After disabling the use of results have been very obvious, you can save a lot of power.
3, reduce internal power consumption of devices. More and more CPU-frequency, high-speed hard drives will bring a lot of energy consumption and increased heat dissipation. Therefore, no special requirement, then the best use within the system or a third-party software to control the drive speed, do not open too many windows and programs in order to avoid CPU overload of work, so not only can reduce the battery power consumption, another can also reduce the bulk heat, in the "autumn tiger" there is the season, this is still a little benefit.
