No power in Samsung Q45 laptop

The rechargeable battery needs to be replaced, go to www.ebay.com type make and model of laptop, refine search to battery.

are you installing it with correct polarity
is one of the battery terminals in the laptop damaged so that it is not making contact

When you first bought the laptop did you fully charge the battery for at least 20-24 hours before use? To ensure the lifespan of your laptop battery is long you will need to follow these easy steps:

1) Charge the battery at least 20 hours before use.
2) Completely drain battery power before you charge it again.
3) Try not to have the laptop battery plugged in if you re going to use AC directly from the wall socket.

You may need to purchase a new battery as this one's lifespan seems to have been reduced as it can only hold 52% charge. When you purchase another follow the above steps.

If it will run off the AC Adapter but won't charge the battery then odds are it is the battery that won't take the charge and not the AC Adapter's inability to charge anything.


Google "dell vostro1500 battery" and change to shopping. You will see many available knock off battery's starting at 20 dollars.

Although AC Adapters go out too. They last a lot longer than batteries do. Today's batteries just don't last. I would say average life span is a year to a year and a half.

Hi

Dont be panic. Your laptop has absolutely no problem.Your manufacturer had set a 80-20 policy for the laptop battery charging such that the battery wont be charged to 100 percent but it will charged only upto 80 percent. The makers of the lap are doing this because to give good life to the battery.You can change it by going into the power options inside control panel.

I have a new gateway laptop with windows 7 and today it said plugged in not charging 8%. I tried everything and nothing worked so I turned it off and unplugged it and took the battery out and put it back in and it started charging...hopefully this works.

probably itz the faulty battery, try replacing it..
i guess ur hdd is also detoriating (as itz emitting much noise), beware!!
however, u shld contact ur system admin/vendor/an authorized service center....

If the computer is connected to an electrical outlet, the light operates as follows:

• Solid green: The battery is charging.
  
  
• Flashing green: The battery is almost fully charged.
  
  

If the computer is running on a battery, the light operates as follows:

• Off: The battery is adequately charged (or the computer is turned off).
  
  
• Flashing orange: The battery charge is low.
  
  
• Solid orange: The battery charge is critically low.

Looks like the AC adaptor is faulty.

Most Dell batteries have an LED indicator that allows users to see how much run time and how much overall battery life are available at the touch of a button.
To check battery charge, press the button and the number of lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge.
To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and approximately more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, approximately less than 60 percent of the charge capacity remains, and you should consider replacing the battery
if the ac adapter will power the laptop without the battery installed its fine. if the cord is fine and your battery is fine its a mother board issue and it will most likely have to be replaced

Your battery not able to hold a charge is a bad battery.
Love your precise description & diagnoses. Wish others would describe their troubles as well as you!

Have a great day!
