Problem status
Iphone5 mobile phone now suddenly charge not into electricity, change friends also not, now all shut down can't open, how to solve it? Do you want to go after the sale, please give an opinion to a netizen
Solutions
First, connect the charger, charge for more than 2 hours, and then see whether the boot, you can try to connect the computer with a
1, check the current battery power of notebook batteries
First look at the battery at this time the amount of electricity, if the electricity between 90%-100%, then the charge is not in the electricity may be normal. Because the laptop to protect the battery life, the number of charges will not be so frequent, only the battery charge is less than 90% (some is 95%) when the charging.
Calculation Formula of capacitor charge discharge time
Set, V0 as the initial voltage value on the capacitor;V1 is the final charged or placed voltage value of the capacitor;VT is the voltage value of the capacitor at t time.Then,Vt = "V0" + (V1-V0) * [1-exp (-T/RC)]Or,T = rc * ln [(V1-V0)/(V1-Vt)]
For example, a battery with a voltage of E is charged to a capacitor C with a initial value of 0 through R.V0 = 0, V1 = E, so the voltage charged to
Database Design Manual 1 Introduction
1.1 Purpose of writing
The paper points out the database design of the computer room charge system, and makes the specific design rules for all the logos, logical structure and physical structure used in the database.
Expected Reader: programmer, database administrator. 1.2 background

b Name of software system: charge
Remember, the first time to write a computer room fee system Document template, a full 12 documents need to write, just spent two or three days to let the master acceptance, the completion of the project, so swallowed the document was written. You should know: the account owed, after all, is to pay. Now to the computer room toll system personal version of the reconstruction phase,(1) abstract the data and design a local conceptual model;(2) Synthesis
How long is the charge time of the notebook battery good?There is a power indicator in the lower right corner of the notebook, if you do not use the power battery can maintain 2 to 3 and a half minutes, the specific performance of different notebook, at the same time the operation also has an impact on the use of batteries, such as: watching movies, listening to songs.No electricity in the notebook, how lon
following figure:
The battery has been dormant due to excessive discharge, the lithium battery will go into hibernation less than 3v, now the voltage of 2.75v (8.26V/3) has been lower than the 3v low voltage limit. In the absence of professional equipment, you can only try the following two ways:
1. To connect the power supply, put a day or so time (on the boot can be), to see whether the self-activation.
2. Battery out, the back of the battery ha
1, first look at the battery is not the problem,
2, the condition allows the cell phone can take down the battery, with universal charge try to see whether can be charged into the electricity.
3. If the battery can be charged with electricity, then the problem of data cable or phone socket. If not, then the battery problem. If the problem is a battery, small series has a small way, with a newspaper wrappe
Project Development Plan (GB856T--88)1 Introduction 1.1 Purpose of writingA project development plan is a preliminary plan that is first done to identify the project to be developed. There is a relatively general understanding of the conditions required for the entire development process of the project. Project development plan intended for readers, developers, managers, and analysts.1.2 BackgroundDescriptionA. Name of the software system to be developed: Computer room

Test Analysis Report1 Introduction1.1 The purpose of writingThe Test analysis report is the process of analyzing and summarizing the function problem of test data on the basis of testing, and the test process is an indispensable part of software development. It plays an important role in the upgrading of software functions. Moreover, for the future developer reading source program, according to test data and results analysis software functions and limitations laid a good foundation. Developing s

To understand the computer Tatsu people should know, ordinary computer USB interface output parameters are generally 5V and 500 Ma. Let's take a look at the charging voltage of the ipad's own charger, which turns out to be "5.1V and 2.1A".
When you see these two sets of numbers, you should know that the ipad is "not charging" when it connects to the PC because the PC-side USB interface outputs voltag
