③ When the adjustment is abounding afterwards CPU assay changes to the adjustment terminal voltage to activate whether the full, and the Accessory through the CPLD controls LED to advertise the adjustment is already saturated.

④ CPU detected AC disconnect, the CPLD to accomplish by switching amidst adjustment and adjustment power, and advantage the cachet LEDs to advertise the adjustment is power.

HP introduced lithium battery standard imperative

According to "China Quality Daily" reported on 26 May, China Hewlett-Packard Co., submitted to the State Administration of Quality Supervision, Inspection report, referred to some of August 2007 to January 2008 during the production of HPPavilion , CompaqPresario, HPCampaq, HP laptop batteries in the series, the number in China, with about 15 000. It is understood that HP will extend the May 14, 2009 announced the fourth installment of the list of notebook battery recall, including four brands of 31 types.



HP brand has occupied an important place in the minds of consumers in China, produced by printers, digital video players and computers are constantly affecting people work, live and learn. 6 consecutive years, HP has been selected "most respected companies, has sold is the world's largest maker of laptops, but in 2008, people began to fall to vgp ac19v19 HP multiple" doors "- including card" door " flash gate "screen" and "cockroaches" door for the incident, including consumers begin to re-examine HP.



HP to expand the scope of the battery recall having touched the consumer psychology In conclusion, why HP and again to expand the scope of recovery is not, HP batteries are a problem, there are other quality Hewlett-Packard the problem?



HP recalls the question of updating lead



In fact, as a recall, HP is not the first time. April 20, 2006, HP said that according to U.S. requirementsConsumer Product Safety Commission, said some of the series, the laptop battery recall Hewlett-Packard and the initiative to implement a global replacement program. HP and the battery manufacturer to confirm, one in 2005 to 10 in 2005 assembly defects of the battery. Hewlett-Packard that these deficiencies constitute a potential danger to the safety of consumers. October 30, 2008, HP announced the HP laptop used for some of the nearly 74,000 to implement a global battery recall and replacement program initiative. May 14, 2009, HP announced the recall notebook battery room.



HP to expand the scope of the battery recall  become the focus of users recently. Hewlett-Packard computer users by the composition of a group of QQ, users have to wonder if the battery model has been recalled in the recall list have been found "not in this column, friends said was" very disappointed. Meanwhile, some netizens questioned again and again to increase the HP laptop battery recall models, "HP battery is not a problem, why have not revealed why the battery does not remember the list?"



Recall of batteries overheating and other issues is the main cause of



I remember HP often associated with problems of laptop battery. HP said in the assembly of certain laptops can be of some batteries posed a potential customer for security, these batteries can overheat, pose fire and burn risk customers.



As we all know, laptops are based on lithium battery materials. And lithium are unstable, overheating, short life cycle of the physical characteristics, in order to improve the stability of the battery, lithium battery manufacturers

Add the other elements in the material. In other words, small groups and thin, which contains a variety of flammable substances in case of short circuit, overheating and other extraordinary skypemate download vista circumstances, the possibility of fire.

In fact, several years ago, began the safety of lithium exposure. Since lithium is potentially dangerous, laptop manufacturers to find ways to solve it. But the current situation is that people in battery life have become increasingly demanding, and manufacturers are in constant demand from consumers, so the performance of lithium battery manufacturers constantly Tiao Zhan. When the speed of technological development is not sufficient for demand, they often sacrifice safety and quality. In addition, safety standards for lithium batteries is also a bit confusing, to regulate the manufacturing process and products will continue to improve safety and reduce the risk of occurrence of Lv, but the creation of a uniform is not easy. The blind pursuit of modern design laptop thin and comfortable for the user ignores the problems of heat, will also affect safety. Low if the safety of the activity of the lithium ion battery, the battery capacity, inevitably, must come down, which in itself is a contradiction.



Industry experts to address the security of laptop batteries, from two aspects, one of the technical solution, using technological means to solve the bottleneck restricting their safety. Secondly, through the standard, through the development of standards, to some extent, establish a business rule.



Introduction of lithium peremptory norm



Currently, lithium batteries have been used in home appliances and other industries. It is because of the widespread adoption of lithium batteries, its production standards are so confusing. It is understood around the world, a standard laptop batteries are lithium into chaos, countries, industry has some standards, but not equal. The safety of lithium batteries has become a major drag on industry, so that the design of lithium ion battery, fully integrated manufacturing process quality control systems of the industry is in a large number security incidents in lithium ion batteries and came to a consensus conclusion.



China's safety standards for lithium ion batteries as the lack of overall planning, first among national and industry, and lack of coordination between the various industry standards, there are some items standard cross, repeated by the Otherwise, there is no standard uniform safety standards guiding both simple, but it also includes hp ac adapter the electrical performance, safety and environment for all general rules, as the nature of the rules. products of the lithium ion battery as a household word, not only the unity of its safety standards, the need for adequate protection of consumer interests, but also reduces costs for businesses, industry needs policy.
