fix laptop problems

Eventually, your laptop’s battery will die. It’s inevitable. Just as humans are subject to death and taxes, laptop batteries are subject to death. (Fortunately, the government hasn’t figured out how to plunder tax money from a battery. Yet.)

If your toshiba laptop battery fails or no longer holds a sufficient charge, you can easily replace it. such as “Toshiba Satellite M55-S139 Battery” Follow these steps:

Toshiba Satellite M55-S139 Battery 6 cells 4400MAH Description:
Voltage: 10.8V
Capacity: 4400mAh
Type: 6 cells
UL certificated cells inside!

1.Turn off your laptop and disconnect the laptop AC adapter.

2.Release the latch or other attachment devices that hold your battery in place.

3.Slide the old laptop battery out of its compartment or storage bay.

Press the release button if there is one and carefully lift the battery out of its compartment.

Avoid touching the contacts on the toshiba laptop battery itself or inside the bay; the oils on your fingertips could reduce the conductivity of the battery.

4、Take the replacement battery out of the box.

5、Slide it into the notch or bay.

6、Close the safety latch to lock it into place.

7、Reconnect the AC adapter for laptop and give the battery a full charge.

Don’t mourn a dead battery! Toss it out!

Keep in mind that batteries are considered to be toxic waste in most communities. You must properly dispose of or recycle dead toshiba laptop batteries according to the rules of your community or jurisdiction. Never just chuck an old computer battery in the trash.

And don’t get all Viking and try to burn your battery, either. That’s just a bad thing.

This tutorial would help you solve the problem that Laptop’s LCD Screen was dim. I will explain how to find the inverter of a laptop, but the tips are not aiming for some special brands or models, they should work for most laptops.

Warning: Please make sure that the laptop is not connecting to any power source including the laptop battery and the laptop AC adapter.

Problem: HP /Compaq NC6400 LCD Screen is dark.

Solve: plug the laptop to an external monitor. If the external monitor displays normally, then the problem is from one of these components: LCD backlight, laptop inverter, LCD cable or video board. Further tests have to be conducted to verify the particular component.

In-order to get out the LCD inverter, the laptop LCD screen must be disassembled,

These are the SPECIAL tools for disassemble the laptop. NOT NECESSARY to have them in this case. (A 6-point star screwdriver, a Magnetic screwdriver)

Open the laptop cover.

Check all corners of the Compaq NC6400 laptop display part for potential screws. In this laptop, there are six of them, four screws at the upper line and two of them at the bottom. All of them are hiding beneath the rubber buttons.

(Also check the sides of the display part for screws since the location of the screws vary from model to model. BE VERY CAREFUL. Make sure that you do not miss any screw, you could DAMAGE your laptop cover when you try to open it.)

Move the screwdriver along the LCD frame slowly, this will slide the frame open. (It is not over yet, for this specific model, there are some other places you need to looking into in order to remove the LCD frame)

After remove the cover, the HP/ Compaq NC6400 LCD Screen frame can be removed along with it.

Pulling out the 2 wire cable plug from the inverter.

before do that, first unscrew a small screw that used to secure the inverter in place.

the 2 wire plug is High voltage AC output to light up the fluorescent tube inside the LCD screen.

Two pins is standard for all today LCD screen, but without some type of the TOSHIBA LCD screen.

after remove the 2 wire plug from the inverter. you can move on to another side.

the wire plug is DC current supply from main board. There are many type of the socket on the inverter board and the wire plug.

In this case, there are 7 pins socket receiving electrical current and current signal from the main board.

There is no standard form for the inverter! You must look for the part number as shown on this photo.

Attention: The part number of the replacement cable must match your cable or else they may not compatible thought they may look similar.

Common for laptops: There are many different type of sockets with different number of pins (4 to 8 pins).

How to Test Your Laptop Battery?

Laptop batteries can fail, or over time can lose their ability to hold a charge. If your laptop suddenly stops cooperating, you can usually determine if a bad battery is causing the problem by removing it from its bay (on the bottom or side of the laptop) and running the laptop from the lalptop ac adapter only. If the batteryless laptop runs properly when connected to the adapter, the battery has most likely kicked the bucket, shuffled off its mortal coil, and otherwise become defunct.such as”Dell Inspiron XPS M170 Battery“

You can further test this hypothesis by substituting a laptop battery that you know is functioning well from another laptop of the same model. You may be able to borrow a coworker’s battery or take the laptop to a cooperative retailer’s repair counter.

If, in the other hand, your batteryless laptop doesn’t run when connected to the laptop AC adapter, either the adapter or the laptop’s internal electronics have failed. Again, if you can borrow a known-good ac adapter, use it to see if the problem is caused by the cords or converter or if the issue lies deeper within the laptop itself.

How to charge for the new bought laptop?what to do to maintain the laptop battery?

Lithium(hydronium) battery (such as toshiba laptop battery ,compaq laptop battery)needs certain electromotive force inside to keep the activity of internal chemical substances. Therefore, you should charge full and use it up. Generally speaking, the first three charging take about six hours. Charge to 100% is ok then. You should not charge only for a short period of time, when the electric power is less than 10%, charge in time. If you used it up completely, it’ll cause damage to laptop battery; at the same time, if the power is more than 60%, you should not charge as possible as you. The laptop battery which won’t be used for a long, should be used to about 50% power left, and then keep it in room temperature dry environment.
