A battery is long ah ?

Lenovo 3000 N500WhetherBatteryOvercharge protection?
A: The long-term use of external power source connected to the battery pack will reduce the life of the battery, IBM ThinkPad R60 battery, IBM battery 40Y6797 IBM ThinkPad T60 battery, try to avoid such use.
Charge the battery at 93 ~ 95% of the time, in order to protect the lithium ion batteries, manufacturers have designed a way to automatically go to full charge indicator drip (as in the load current) slow load, it needs more time to access 100% of the state. And 99% is generally considered full power, insert the adapter into the case shows that the condition of charge exchange, using the AC adapter.
Excessive loading and unloading during the lithium-ion batteries can cause damage to the intuitive understanding positive and negative, from the molecular level, excessive discharge of carbon anode will lead to excessive release of lithium ions and laminar structure pops collapsed too, will be charged too much on the negative electrode of lithium ion hard carbon structure to go, and do a bit of lithium ions can not be released. Therefore, the lithium ion batteries have been supplemented by a circuit overload control. The charging time cause the battery from overcharging, since the index related to the circuit before disconnecting the circuit in the past, but by over-discharge, especially the battery soon will be no place in any case, the battery will continue to add because there is no electricity in the air exhaust caused by excessive electrical discharges.
So if you do not need much time to charge the battery completely safe (generally considered 40%) and then stored.
1, "activate" absolutely necessary, and indeed the actual use of the battery has a positive effect, especially to calibrate the parameters of the battery.
2 LED indicates the "full" when the fact is that the burden remains slow, retention of the actual load (overload protection), but after several hours.
3, the battery life of lithium ion and the discharge of their lives in the 300-500 times, but even if you do not need to buy back its consumption of life is also slow.
4, a battery to maintain the longer form: the battery to 40% in a cool place to place every month to do so after a full charge and discharge capacity of up to 40% will be saved.
Lenovo Y730 Battery problem
1. Lenovo Y730 been BatterySoon special sound of the siren, Lenovo 3000 G400 battery only memory of the machine to pull the alarm when the same as normal?
A: This alarm sounds normal, Lenovo is designed.
2. Lenovo Y730 of the two main issues:
1. became a music board self-test on the display, IBM ThinkPad R60 battery, IBM battery for IBM ThinkPad T60 Battery 40Y6797 do not know how to get rid of?
A: The configuration of the motherboard's BIOS.
2.Y730 story about the power button has a button, is a key to reducing curing, I used the D version of the popular dish in the market are not in the press, GOST disk software company can only occur in the installation interface, regardless of any time you can reinstall just the interface?
A: This problem is not piracy reasons. You need to install the original XP, no version of Ghost, because time is not reinstated Spirit reformat the partition. VISTA XP partition to different formats.
3. Lenovo Y730 and Y730A is PEI-What is the difference did not, Lenovo Y730 is this model?
A: Only Y710, one was on behalf of its independence.
4.Y730 sound card can be placed in the same time and with a speaker, in what ways, not the external sound card. How to weld what are the graphics?
A: 1. sound card output only one way speaker can not be used instead. 2.Y730 replacement card, the specific costs please contact the College of the service station.
R400 Lenovo battery problem
1. I just bought a Lenovo R400 this, one day BatteryFrom 100% of the total power is shrinking every day. Today it has become 95%. Who can help me think why?
R: The battery is a self-discharge of the situation, losing a little power is a normal situation. IBM ThinkPad T60 battery, evidence of its power management software to reset the battery indicator function, or check the status of the battery is. If the situation worsens, or battery life dramatically changed little, and early warning service stations battery contact.
2. Lenovo R400, and the quality is worth buying now?
R: A week ago only to take the ThinkPad R400 2784A34, feeling above can also be used; IBM ThinkPad R60 battery, IBM ThinkPad T60 battery, IBM 40Y6797 Battery, I think the R series, SL series is better than a number, is the unity of the demolition, of course, increase the hard disk of the same interface.
3. Lenovo R400 BatteryCan set the threshold for charging, and X61 (and 20% power when the load)?
R: The machine does not work, hardware problems, and the positioning of the various products.
IMB 4.R400 battery is manufactured or produced by Lenovo?
A: The products of Lenovo, IBM point s durable.
5.R400 batteries need to activate? Or when the battery in the factory has been activated?
A: Each brand and model of machine to be activated in the first use of automatic shutdown is used in more than 10 hours of charging.
