Problems Power

Problem-solving process by identifying what Begins always works.  If the problems associated with power, (the battery is one cause of the laptop will from not turn on) the first step is to Ensure power to the laptop..  That this means checking the battery LED on the transformer fire, and if not (or do not have the LED), make sure the ac adapter is plugged into an electrical outlet That good..  You can check That by unplugging the ac adapter and just plug the lamp or to check by current testers.

The next question is whether or not there is a small LED status lights on the lamp plugged into a laptop with power.  Even the oldest models usually have a good light power status..  If you have a positive and notebook power status earnest Also note light up, the next check is the battery.  Some notebook models will from not operate without batteries installed properly, find out on the internet if your laptop will of models operate with the battery dead or missing. .  If the battery is not a problem and the laptop still does not work with the power of good status, it Could Be a problem with power regulator, or more likely, regulation of electric power (power in component) or the main board.  Overcoming the problems of regulation or the motherboard requires test equipment or spare board to swap, and are beyond the scope of this article.  (We will from this portion discuss in more detail in other sessions)

There is very little difference Between troubleshooting Laptops Dell, Toshiba Satellite, IBM ThinkPad, HP Pavilion (and Compaq) or even Apple PowerBooks or iBook. .  The basic design of all the Same laptop, although one model uses an Intel CPU, the other AMD and Transmute Also PowerPC is low.  A Toshiba laptop troubleshooting May Technicians prefer to start with a battery, Such as the famous weak, Such as HP and Compaq notebooks problem Often Begins with the RAM.  However, not all models cans be marked has a weakness on the Same issues.  not follow a logical process of elimination.  Just because one model of Dell tends to blue spots on the screen Pls perform certain age a Dell notebook memproksi That continues with the Same problem.

IBM and Sony and Apple laptops Generally regarded as higher quality Than other popular brands, but They are all experiencing similar problems due to overheating, wear, and the occasional run of bad components.  Batteries are a special subset of power problems That are happening.  The older NiCd batteries are specifically vulnerable to the problem.  If it is not perfect in the charging, the battery cells begin to record the previous level as a new maximum level, and Some May even individual cells reverse.  Ni-MH (Nickel Metal Hydride Battery) Replaced the which NiCd (Nickel Cadmium) for the standard model is Somewhat better, but not cans They fight bad charging control circuitry or software controlling bad..  All laptop batteries, whatever the form, consists of a number of low voltage cells connected in parallel or series to Achieve the required operating voltage.

Some older notebooks require you mengsiklus battery continuously, only works on AC power as long as it takes to recharge the battery.

Many new models Should Be fully charged battery about once a week, but do not worry Otherwise leave it plugged in for a long time, and the latest designs no matter what you do for a laptop really get the charging of the battery for a reasonable percentage  of time.  If you think your battery runs down too fast, make sure you have enabled aggressive power saving mode in the software (usually accessed through the Control Panel icons or manufacturer) That dim the screen, slow CPU, and let the hard drives spin down Pls note  in use.  Also, keep in mind That the estimated level of residual resistance of the battery That the caused the alarm on the screen cans be set by the user, and if your default settings are very conservative (Between 10% and 20%), you May Want To  experiment with a lower level (Between 3% and 5%) will of the which still give you time to save your work and turn off the laptop before going into hibernation.
