When should you replace a laptop battery, screen or keyboard?

Laptop parts slowly wear out. If you catch the signs early, repair is simpler, safer and can extend your laptop’s life.

At Karthik Computers, we handle laptop repair and upgrades (SSD/RAM upgrades, battery, screen and keyboard replacement) at our Kovilambakkam service desk. If you are unsure what is wrong, you can still start a conversation by sharing the model number and photos.

Signs your laptop battery needs replacement

  • Battery percentage drops suddenly or the laptop shuts down even at 20–30%.
  • Battery lasts only a few minutes on full charge.
  • Battery is swollen or the bottom panel/trackpad is bulging.
  • Laptop works only when the charger is plugged in.

Important: If you see swelling or the body has started to bulge, stop using the laptop and disconnect power. Call or WhatsApp our service number to ask what to do next.

When a laptop screen needs changing

  • Visible cracks or liquid marks inside the display.
  • Vertical or horizontal lines that do not go away.
  • Screen flickers, goes white, or turns black but the laptop power light is on.
  • Patchy brightness or coloured blobs on the panel.

Some issues can also be caused by the cable or graphics. Clear photos of the screen help the technician judge if it is a panel change or something else.

Keyboard problems: repair or full replacement?

  • Keys not working at all, or typing the wrong characters.
  • Keys repeating by themselves or getting stuck.
  • Liquid spill on the keyboard followed by random behaviour.

On many modern laptops the keyboard is part of the top cover. Whether only the keyboard or a larger part needs changing depends on the exact model.

Why the exact laptop model number matters

Battery, screen and keyboard part numbers change between generations and configurations, even within the same brand. Using the wrong part can cause poor fit, charging issues or no display.

Before we can confirm options, we need your exact model. You can also explore our full Laptop repair & service details if you have multiple issues.

How to share details with the service desk

  • Model number: Usually printed on a sticker at the bottom of the laptop, under the battery flap (on older models) or on the original box.
  • Photos: Take clear photos of:
    • Any cracks, lines or flicker on the screen.
    • Swelling or gaps around the battery area or trackpad.
    • Damaged or missing keys on the keyboard.
  • Short description: Mention how the problem started (drop, liquid spill, age, etc.).

Send these by WhatsApp to our service number so the technician can guide you on the next step.

Repair vs exchange: when to consider a different laptop

If your laptop has multiple faults (for example, weak battery, broken screen and performance issues), it may be better to put that money into another laptop.

  • Old laptop exchange: Check if your current laptop can be exchanged and reduce the cost of the next one.
  • Certified refurbished laptops: Business-grade ThinkPad, Latitude and EliteBook models with Grade A body, battery health above 80%, fresh Windows install, 6‑month Karthik Computers warranty, 7‑day replacement and GST invoice.
  • If your laptop is slow but the screen and keyboard are fine, consider an SSD & RAM upgrade along with a battery change instead of replacing the whole system.

Questions, answered

How do I know if my laptop battery needs to be replaced?

If your laptop shuts down suddenly, runs only for a few minutes on battery, or you see swelling or bulging on the body, it is time to get the battery checked and likely replaced.

Why do you need my laptop model number for screen or keyboard replacement?

Battery, screen and keyboard parts differ by brand, generation and even sub-model. The exact model number helps us identify compatible parts and guide you correctly.

Can I WhatsApp photos of the damaged screen or keyboard?

Yes. Please WhatsApp clear photos of the issue along with the laptop model number to our service number so the technician can suggest the next step.

My laptop needs battery, screen and keyboard. Should I repair or exchange it?

If multiple major parts are faulty, it may be better value to use an old laptop exchange offer or move to a certified refurbished laptop instead of repairing everything.

Do you offer upgrades along with battery or screen replacement?

Yes, we handle SSD and RAM upgrades along with battery, screen and keyboard replacement. Share your model number so we can check suitable upgrade options for your laptop.
