Most machines are all kinds of battery protection circuit, when the laptop battery temperature is too high or when the discharge current is too large, probably because the battery protection circuit moves beyond the standard, and thus causing the battery power automatically force the issue.

The most common situation is that the use of DELL laptop battery is running at full speed when the current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery, in which case do not panic, as long as the Disconnect peripherals to wait about 10 minutes, you can reboot.

There is also a common situation is that laptop computers in a hot environment, high-load operation using the battery, so that the ambient temperature plus the heat generated by the battery self-discharge battery protection circuit may exceed the preset temperature, which is particularly high frequency machine In the high-temperature environment may occur after high-speed operation. Encountered such a situation should remove the dell Inspiron 6400 battery placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment, the use of high-load laptop. IBM in 2001 after Chupin notebook computers, power management software Battery MaxMiser can display the battery temperature and discharge current, but not every brand-name products have this powerful.

In order to maintain the BIOS state, many laptops have the battery calibration repair option, simply speaking, this function will be the notebook’s battery is full and complete discharge to no electricity, and then re-filled, so that for long-term result of not completely discharge the accumulated have a certain role in error correction. However, please note the correction in the BIOS spent rather a long time, if you do this, preferably before going to sleep.

Many models also have Windows, discharge functions. This can save time, while working will be corrected:). Battery Calibration will not be too frequent, often the depth of discharge is to bring the dell Inspiron 6000 battery life shortened, it is recommended two to three months to do it once.

Laptop Troubleshooting 4: Interface question

Laptop computers most likely failure of the interface is a network interface, USB interface, IEEE1394 interface, and headphone jack, etc. The main problem is the use of poor quality and improper operation of the plug caused mainly as a pin is damaged, interface circuit burned, the port surface rust and other coatings.
Solution: the interface pin damage is usually due to excessive force when inserting or receiving the wrong equipment, caused by, so when the access device interface, a good idea to look at whether the match, if they feel the process of access to significant resistance, then the need to look at the pins is bent, to avoid further bending Er Shi pin fracture. If the pin has been obviously bent, you can clamp off the state of its set right, remember to first shut down, otherwise the pin interface circuit short-circuit may cause fire.

Note: the port is a gateway to the external computer, not a port of the computer as a person without friends, loneliness, protect notebook port is also a important thing. Now, most laptops are equipped with a baffle port can be used, in the absence of the case should be connected together on the tailgate, and do not let interfaces encountered water or corrosive things.
