Guidelines for Adapter Care

Plug the adapter firmly in the socket to avoid power surges. Insert the adapter jack in the laptop carefully. Tilting or pushing too hard may damage the pins inside the laptop. Coil the power cord neatly before storing it in a bag. Improper coiling may tear the wire inside and cause short circuit. Exposure to extreme heat or cold may damage the adapter. Handle the adapter with care and do not drop or expose to moisture.

Easy steps to pick the right laptop AC adapters.

  1. Finding the right "tips" - Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, laptop AC adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called "TIP" which you will plug this tip into the "DC IN" in your laptop. Your laptop won't work on the wrong tip. You can only use the “matching Tips" DO NOT try to force it in.
  2. Finding the right "output voltage" - Different laptops were designed to consume power varied by equipments such as CD-Rom, LCD size, CPU maker and CPU speed. You require using the "matching voltage”. Only use the laptop AC adapters output the matching voltage of your laptops. You can easily locate your laptop voltage. Mostly, voltage is printed on your laptops. You also can check your laptop manual.

Guidelines for Battery Care

  1. New Laptop Battery isn't charging. Is it defective?

    Generally new Laptop batteries come in a discharged or sleep mode condition. It must be conditioned to operate at its full capacity by charging & discharging. Fully charge/discharge battery up to 4 cycles before achieving full capacity.

    When charging for the first time, the Laptop may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. Sometimes the Laptop charger will stop charging a new Laptop battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This is a normal condition to prime a brand new battery.

    Please check the Laptop BIOS interface. BIOS are generally set up to read an OEM (Original Equipment Manufacturer) battery. The replacement battery may not communicate effectively with the Laptop software. Please have the Laptop system BIOS updated and retry charging as normal. BIOS updates are available at the Laptop manufacturer’s support website.

    A new battery may cause the battery power icon on the Laptop to indicate you have a low battery condition. We recommend that you let the battery charge overnight in the Laptop. It may be necessary to remove and replace the battery and restart the Laptop with the battery installed in order for the Laptop to start up sequence to properly recognize the new battery.

  2. How long do typical batteries last?

    Lithium Ion batteries lose capacity to hold charge with every charge-discharge cycle. The life of a battery under normal use is around 500 charge-discharge cycles. The average Laptop should give you between 1½ to 3 hours of run time. Though the following various factors that affect a Laptop battery life.
    The Ambient temperature (20 -25C) at which it is used.
    Frequent full discharge harms the battery health. If a Laptop battery is discharged past the critical 3% level, the battery may not be able to be recharged again. A Laptop battery needs a small amount of power in it in order for it send communication back and forth with the Laptop to recharge the battery.
    High end graphic applications require more power and deplete battery faster. e.g. animation software, 3D games, high graphic application, playing of music or movies.
    Use of active peripherals drawing power directly from Laptop. e.g. LCD brightness levels , USB Pen drive, USB modem, External optical drive, external speakers etc.

  3. Maximizing performance of Laptop battery?

    Ensure maximum performance of the battery by optimizing the Laptop power management features as suggested manufacturer’s manual.
    Minimize use of battery power of the Laptop. Use the AC mains through Laptop adapter when ever wherever possible.
    Adjust brightness of the screen at the minimum possible level.
    Switch off power to the laptop or hibernate if not in use.
    Disconnect peripherals which consume power from the battery, if they are not in active use e.g. CD/DVD Drive, external HDD, cards etc.
    Adjust power management settings on laptop to turn off hard disk and monitor when not in use for an extended period.
    Remove unnecessary files from startup to minimize the time consumed to get started.
    Remove unwanted applications and temporary files regularly from the laptop to perform desired tasks swiftly.
    Turn off the speakers unless absolutely necessary.

  4. Laptop Battery Care

    Use the battery at an ambient temperature between 20C to 25C.
    Avoid discharge below 3%.
    If Laptop is to be stored over 2 weeks, remove battery from Laptop and store separately.
    Do not expose to moisture, rain, or soak in water.
    Do not short circuit, disassemble, crush, drop, hit, puncture or otherwise abuse the battery.
    Keep away from fire, or other sources of extreme heat. This may result in explosion.
    Use battery only for its specified purpose.

  5. When to buy a replacement battery required?

    On regular battery use, the battery begins to fail the running time of the battery and full charge rate will begin to decline.

    Ideally, when battery supplies less than 30 minutes or less of charge, it is time for a replacement. Li-ion Laptop batteries will wear out slowly over time on each charge-discharge cycle, providing ever shorter battery run times on every use.

  6. Factors Affecting Battery Life

    Li-Ion batteries lose capacity to hold charge with every charge-discharge cycle. One cycle of charging the battery and using it before recharging is called charge-discharge cycle. The loss is gradual, but irreversible. Battery life depends upon the ambient temperature at which it is used. Higher temperature hastens ageing. High charge level hastens permanent capacity loss. For example, running the laptop for an extended period on a docking station while power is supplied through an AC wall socket, results in high charge level, which may harm the battery.
    Frequent full discharge harms the battery, while partial discharge/ recharge are better for longer life. Battery self-discharges at a higher rate if left in an unpowered laptop. Leaving the battery at very low voltage level for an extended period accelerates loss of Full Charge Capacity ( FCC). High end applications reduce battery life e.g. animation software or 3D games reduces battery life more than word processors.

  7. What do the power ratings mean - mAh, Volts, and Watts?

    MAh (Milliamperes) represents the amount of stored energy in your battery. 1000 Milliamperes = 1 Ampere. The more mAh capacity - the longer your battery will last. This does not mean that the battery is not the correct replacement, but rather it is a longer lasting battery. Voltage in a battery refers to the volume of electricity that is delivered to your computer. The amount of energy that comes from your wall outlet is far in excess of what you need to operate the tiny circuits of a computer. Hence your power adapter contains a brick or bar like box that decreases the energy to a much lower voltage rating. Each computer manufacturer designs their computers for the appropriate voltage requirement. Your battery pack will then be engineered to match the voltage of the power AC adapter. Laptop battery packs are composed of several battery cells that are wired together in series. By combining the cells in this fashion, higher volumes of energy can be delivered to your laptop computer.

  8. Can I specifically calculate my battery run time?

    You can determine your laptop’s run time when you know how many watts your laptop uses and the total power capacity your laptop battery has. Here is how you can calculate this yourself. Battery capacity can also be measured in Watt-Hours. Watt-Hours are calculated by multiplying Volts * Milliamperes.
    Here is an example: Your Laptop runs on 14.8 Volts, and your battery rating is 4400mAh total capacity, then total Watt-Hours is 14.8v * 4.4Ah = 65 Watt-Hours. Watt-Hours measure the energy which powers one watt for one hour. If your laptop runs at 20 watts, your run time will be 3.25 hours (65 Watt-Hours / 20 watts Laptop pc power use).

  9. Will a higher milliamp (mAh) rating on my battery damage my laptop?

    No. Higher mAh ratings indicate that your battery will last longer. Although the milliamps may be higher, the voltage will always remain the same. If you have received a laptop battery that has a completely different voltage than your original laptop battery, please contact us immediately.

  10. Is it normal for a battery to produce heat while it is being used and while charging?

    Yes. Laptop batteries produce heat when they are being charged and also when in use. Heat is a natural byproduct when energy is transferred within the battery.

Lithium-Ion ( Li-Ion ) battery facts

Lithium Ion ( Li-Ion) batteries are rechargeable in which a Lithium Ion moves from the anode to the cathode during discharge and from cathode to the anode while charging.

Nickel Cadmium ( NiCad) and Nickel Metal Hydride ( NiMH) are also rechargeable batteries. However Li-Ion batteries are now almost the de-facto standards, as they are lighter, have higher energy storing capacity and retain charge longer than similar sized Nickel-based batteries.

Li-Ion batteries are environment friendly as they do not contain toxic material such as Cadmium or Mercury.

Guidelines for LCD Screen Care

  1. What is a compatible LCD screen

    Replacement LCD screen require a great deal of compatibility check due its wide range of technical specifications.
    Different types of screens are used by Laptop manufacturers when assembling a single model of laptop, as a result, more than one type of screen can be used in the same laptop model.
    Also, LCD screen manufacturers release new models of LCD screens every 6 months or so, as a result, one's original screen may be outdated and not available any longer.
    Exilient has a vast experience in the understanding of such compatibility to ensure that Laptop LCD screens we offer are the exact replacements of your laptop models or fully compatible equivalent types. Please Note, replacement of the screen requires technical skill to open the Laptop to be able to replace the LCD screen.
  2. Understanding the LCD Technical Jargon.

    LCD screens require a backlight system to operate; there are two backlight systems in use today: CCFL and LED.
    CCFL - Cold Cathode Fluorescent Light is an older backlight method, which utilizes a daylight specter fluorescent tube and an inverter which powers it.
    LED - is a newer backlighting system which does not use an inverter, and instead of a fluorescent tube it uses a strip of LEDs (Light Emitting Diodes).
    Glossy or Matte finish : Both are entirely interchangeable since the difference lies only in the type of the screen surface finish.
    CCFL type LCD and LED type LCD are not interchangeable and thus not compatible for use in the Laptop screen type.

  3. Which type of Laptop LCD do I need for replacement?

    The size of screen, resolution of screen and the backlight type of the screen will identify the correct LCD required for your Laptop.
    Size: The Laptop models from manufacturers come in different screen sizes. The popular models have 8.9”, 10.1”, 10.2”, 12.1”, 13.3”, 14.0”, 14.1”15.0”, 15.4”, 15.6”, 16.0”, 17.1” and 17.3”.
    Resolution : Screen resolution is measured in horizontal and vertical pixels of the LCD screen. ( e.g. 1024x768, 1280x1024, 1366x1280 etc).
    Backlight Type: Generally CCFL or LED.
    While you may be able to confirm or all the above specifications of your Laptop model , the most sure method is to have the LCD taken off the Laptop and verify the manufacturer’s part number mentioned on the rear of the LCD screen.
