Are you noticing that your laptop battery is not lasting as long as it used to? Are you having trouble charging it? If so, it may be time to replace your laptop battery. Here are some of the signs that you need to replace your laptop battery:One of the most obvious signs that it may be time to reevaluate your laptop battery is if it runs out much quicker than before. If your laptop suddenly shuts down, even when it's mostly or fully charged, this could be a sign that the battery is faulty. To check if this is the case, connect your laptop to an external power source and see if it turns on.
Another sign of a dead laptop battery is if it swells. If you have a removable battery, you can take it out and check for any cracks in the case. If your laptop has a permanent battery, look for any signs of swelling near the chassis. To find out if the problem is the battery, connect the laptop to an external power source and leave it off overnight.
When you turn it on and Windows loads up, check the battery icon in the system tray. Hover over the icon to see a status message and a percentage, which represent the battery charge level. If it says “Plugged in, charging”, then the battery is working, even if its capacity has dropped significantly since you bought the laptop. If the status message says “Available at 0%” (plugged in, not charging), then the battery is not receiving power and is likely dead.
Alternatively, if there is a red X next to the battery icon, Windows won't be able to detect the battery, which could mean that it's faulty. Finally, if your laptop charges at a slow rate or only charges when plugged into an outlet, then you may need to replace its battery. If your laptop looks swollen near the keyboard or touchpad, then this could also indicate that its battery is swollen.
