Concrete repair steps:

1. Setting
If the laptop battery should repair to the best state (no aging batteries), this is the most important place. Therefore, we should pay attention to.
(1) Open My Computer, Control Panel, Power Options Power use of the program, the use of batteries that
Full-time parameters entry named “never”.

(2) to alert that the project hook removed,
This is done to the battery when the laptop down to how many per cent when the program will not be executed.Laptop battery power to run a true After completion,there is no remaining power interference.

Charge-discharge description of specific steps:

In doing the above settings, On the full release in accordance with the principle of end to the battery charge and discharge, and laptop battery recall that bought back the activation steps,and my last time writing notebook battery is fully charge and discharge Gonglue do?
In accordance with that principle to the battery charge and discharge back and forth three times.

Be able to offset the curve of the battery to correct the fix coming.

Static electricity generation and trigger is a natural phenomenon, we can not be completely eliminated, but as long as usually more careful, it can be avoided. To deal with static electricity, we can take the “anti” and “release” hands. “Defense”, we should try to use cotton clothing and home accessories products, as the fabric, try to avoid the use of chemical fiber carpets and a plastic as the surface material of the furniture, in order to prevent friction electrification. “Release” is to increase the humidity, so that localized electrostatic easy to release. When you use a computer before, you should immediately wash their hands face, on the one hand to maintain a healthy, while also allows the electrostatic charge on the surface of the skin to release the water out. In the winter, we should try to use a high moisturizing cosmetics. Common humidifier. Some people like the indoor rearing ornamental fish and daffodils are also regulating indoor humidity a good way. The daily use of desktop computers and laptops, there are a few tips to note:

A notebook to make use of an external power supply

We know that the laptop will have in the course of currents, these currents can not be released if there is no conductor contact, if the encounter with the static electricity produced by the body, it will generate electrostatic discharge, resulting in blue screen, crashes. In view of this situation, it is recommended to use an external power supply, laptop power adapter three phase plug at the same time maintain a good grounding. Not only can effectively prevent the leakage, but also can prevent the accumulation of static electricity.

2, access to computers before discharge

Due to environmental dry friction, the body has accumulated a large number of charge, often in contact with notebook notebook damage caused instantaneous discharge occurred. Therefore uncertain whether the electrostatic accumulation of the body, first after the release of the body static electricity using a laptop. With the books before, it is best to wash your hands, water well to eliminate static electricity, especially in motion a long time (sports events to make clothes and friction, resulting in a large number of static electricity), after; if too lazy to wash your hands, then take a look around there is no ground metal objects can also have contact with both hands effectively eliminate static electricity. Also to be noted that as far as possible not to touch the books by hand directly connected with the internal circuit elements, particularly the interface, in the next, when particular attention to USB.

3, on a regular basis to the computer clean, efficient addition to static electricity

On a regular basis to the computer to do thorough cleaning, you can effectively reduce the accumulation of dust, while you can use anti-static cleaning materials for cleaning, to help reduce the accumulation of static electricity. Baxter clean your computer cleaning of the three detergents, all contain anti-static formula, can effectively play a protective effect, reducing static electricity, to protect the computer role.

How to deal with static electricity after a fault occurs

Notebook for everyday use, the most common are contact discharge, leading to a normal laptop can not boot. If this situation occurs, you can remove the battery after the elimination of its own static, unplug laptop power adapter, notebook and put it aside for half an hour’s time. Again after a separate access to the power adapter, generally can be a normal boot. If you still can not boot, or the repeated occurrence of the phenomenon of static electricity caused not boot and should be sent to notebook manufacturers to conduct a comprehensive inspection office, if necessary, some parts may need to be replaced.

1, Concept of ACPI

ACPI: Advanced Configuration and Power Interface

There are several modes of ACPI:

S0 to normal.
S1 CPU to stop working.
S2 CPU shut down.
In addition to memory outside the S3 components are to stop working.
S4 memory write information to disk, all the parts stop working.
S5 closed.

ACPI power management mode to use hardware and software requirements can be fully supports the ACPI function.

If you encounter problems in use, you can try to upgrade the latest Acpi.sys file.

In addition, the hardware of the ACPI support is essential. Chassis power supply 5 volts to the motherboard at the same time, we must make current stabilized at more than 720 milliamperes to be able to make a computer in a short time from the “sleep” state wakes up.

The program can be achieved by selecting the power supply power management, power management program is the computer power on the use of a group of settings. Windows2000 provides the following three kinds of preset power management program (always open, portable / laptop, home / office desktop), the user can also set up their own computer into standby mode or turn off the hard drive and monitor the waiting time required.

2, ACPI and APM Comparison

APM 1.0 & 1.1: the implementation by the BIOS Power Management;

APM 1.2: operating system, the definition of power management time from the BIOS is responsible for implementation;

ACPI: BIOS collection of hardware information, define power management solutions; by the operating system responsible for the implementation.

APM is a software solution, therefore, with the operating system-related, but ACPI is an industry standard, including software and hardware specifications.

1) How to determine the system is in S1 or S3 mode?

A: The S1 sleep mode, ACPI, only the CPU to stop working, other equipment are still in power-up state. The S3 in the ACPI mode (BIOS-> Power Management -> Suspend to RAM set to Enable, among other equipment are situated outside the memory power-down state. Therefore, to determine the system is in S1 or S3 mode mode The easiest way is to carefully observation system situation: In the S3 state, all the equipment to stop working, even if the pop-up button on the drive can not open the drive door. In the S1 state, optical drive door is open. In addition, S3 mode, the system is completely quiet , all the fans are stopped. At this point system can not wake up from the keyboard. manual method can only be awakened by the power button on the front panel.

2) To achieve STR, so why not cut off the power after shutdown?

Answer: STR function is turned off, it will be the operation of the system information stored in memory, the next boot directly read the memory information, and return to pre-shutdown state. Its advantage is to start very fast, and can keep working condition. The disadvantage is that, even after shutdown, we can not disconnect the computer power supply. Because the data in memory will be lost once the power cut off.

3) In the closing Win2000, display “now safe to shut down” instead of automatically close ATX power supply, how should I do?

Answer: can try the following approach: choose “Settings / Control Panel / Power Options / Advanced Power Management”, if the machine supports advanced power management, then select the “Enable Advanced Power Management Support” and then in the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon Mid PowerdownAfterShutdown for 1; if the machine does not support advanced power management, then, unfortunately, only in the closed system, the display “now safe to shut down?” had to manually cut off power supply.

4) does not care to “Close Windows” dialog box “Let the computer to sleep” to the lost, and ask how to restore?

A: Generally speaking, such problems as long as the reinstall motherboard drivers, restart the future should be able to solve the problem, you can also “Control Panel / System / Device Manager” in the “Advanced Power Management support” deleted, and then Reboot the machine, according to Windows2000 system can also be prompted to re-install solve the problem.

Dell is going big on personalisation with the 15.4″ screen multimedia laptop Studio 15, with five colours and 11 artistic designs available to choose from. The Studio 15 can be equipped with an Intel Core 2 Duo and dedicated ATI graphics. It comes with a slot-loading DVD drive, backlit keyboard, sleek drop-hinge design, widescreen glossy display and touch sensitive buttons. Software wise the Dell Studio 15 includes a unique Apple Mac OS X launch dock.

Parsing the intended markets for Dell’s ever-shifting in-house brand names requires a bit of tea-leaf reading, although it’s been easier of late, with the company stripping down its consumer brands to just the Inspiron and XPS lines. Now the company is adding a new line between the budget Inspiron and the high-end XPS. The new Studio line, as personified by the $1,250 15-inch Studio 15, has the same tapered shape, slot-loading optical drive, and rounded hinge as the Dell XPS M1530, but a similarly configured Studio system costs roughly $300 less than a similarly outfitted XPS.

The trade-off is mostly in size and finish. Even though it has a similar look, the Studio laptop is about 25 percent thicker and slightly heavier than its more upscale XPS cousin, with plastic accents instead of metal. We’d be tempted to toss in the extra $300 for the brushed-metal wrist rest and slimmer design of the XPS, but the Studio line does offer personalization options (lots of colors and graphic imprints) beyond what’s available for Dell’s other laptops, along with a slot-loading optical drive and credit-card-style media remote for about $200 more than a similarly configured Inspiron 1525 (not including discrete graphics, which are not available on the 1525).

While clearly inspired by the popular XPS M1530, the Studio 15 has a more angular look, with its large side hinges curving the screen down at a sharp angle; the XPS presents a more rounded look. At 6 pounds, it’s a bit heavy to tote around every day, but still at the lower end of the 15-inch scale, around 6 pounds. Our early review unit had a matte midnight blue lid, but there are a variety of color options. We’ve also seen some leaked shots online of several artistic designs motifs that should be available in the future, which we’ve previously covered on Crave.

On the whole, the Studio 15 has a good array of connectivity options. Down the left hand edge you’ll find both HDMI and VGA output, Gigabit Ethernet, USB, a combo USB/eSATA port, 4-pin Firewire, microphone and two headphone sockets. Flip over to the other side and you’ll see a power connector, an additional USB port, memory card reader (SD, MMC, Memory Stick), ExpressCard 34 and a slot for the internal DVD writer. If you’re hunting for the power switch, you’ll find that nestling in the middle of the screen hinge on the right hand side.

Symptoms of laptop:

It’s a Toshiba Satellite A105-S2712 for repair with the battery charging problem. Many laptop-users do not have a lot of experience with these laptops because it is a new model. The customer complained that the laptop will not charge the battery when it is plugged into the AC outlet.

The laptop didn’t turn on when we tried to start it from the battery. The battery charge LED didn’t light up when the laptop was turned off and plugged into the AC outlet. It means that the battery is not charged while the LED didn’t light up when the laptop was plugged into the AC outlet. The laptop starts fine when it is plugged. When you  move the mouse over the Toshiba Power Icon in the lower right corner, the balloon will pop up and there is a line in there: Battery Remaining: N/A.

Problem repair procedure:

By updating the BIOS we can easily fix the problem. It says that the BIOS version should be at least v1.30. So, Download the right version at Toshiba website. Select your laptop model and find any downloads for the BIOS. In the BIOS change history you will see the description of changes.

After updated the BIOS, the battery charging problem disappeared.
