Plugged in not charging

I have Lenovo Laptop (Think Pad),  I am using the charger provided by the Company and it was working perfectly fine.  But last two days I am finding that the battery is not full and I have tried different combinations and checked almost everything but not successful in getting the battery to be charged.  What should I do now to get the battery to be charged; now on 23% charge is available.  It shows the message – Plugged in not charging. How can I make sure that recharging starts in my laptop. Please advice.

Lenovo laptop was being used by me few days before and I had the same problem.  Sometimes when you do not switch off your computer this type of problem occurs.  I will suggest you to switch off your laptop and then wait for a few second and then you can restart your computer and most probably your problem will be solved.

Lap top and Battery system

A lithium-ion battery is a rechargeable battery type.  The lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the consistent components of a lithium-ion cell.

Lithium-ion batteries are common in consumer electronics.  For notebooks or laptops, lithium-ion cells are supplied as part of a battery pack with temperature sensors, voltage converter/regulator circuit, voltage tap, battery charge state monitor and the main connector.

Li-ion batteries are considered as non-hazardous waste. The metals extracted out of the batteries are recycled. They are also considered as rechargeable battery, storage battery, secondary battery.  The laptop will get hot due to usage.  Hence adequate precautions need to be taken whilst working on the laptop as it will be harmful the body, if the body is directly in touch with the hot part of the laptop.  There are covers available in the market to avoid direct contact of the laptop with the body. 

Many companies are making laptops.  Laptops are convenient computers.  It can be used while doing other simpler activities.  Like we can use it in the bed, it can also be used at the time of breakfast or taking lunch and dinner.  The different brands of laptops and different specifications of laptops often make the customer confused.  Hence it is always better to buy a brand or the system which we know are able to handle it comfortably.  Lenovo is not at all a bad company but in fact they are the world’s leading personal technology companies.  I have also used the Toshiba brand of laptops but had one problem with it as it used to get heated up soon.  The heat was so high that sometime it was difficult to place the laptop on the lap.  There are other brands like Dell and HP brands.  Any laptop if we buy will be able to perform the similar functions. The laptops should be handled carefully in order to have a maximum life of it.
