If the laptop only works when it is connected to the charger, the battery may need to be replaced.


  • Laptop batteries have a limited number of charge-discharge cycles they can perform. The battery will usually run out of charge-discharge cycles after a few years.
  • Prolonged exposure to very high or very low temperatures can deteriorate a laptop battery.
  • If the laptop battery stays at a very low charge (or completely discharged) for prolonged amounts of time, the battery will likely lose its ability to recharge.

Solution: Replace the battery. Refer to this guide for replacing the laptop battery.

If no sound comes from the speakers when sound should be heard, the speakers may be faulty and probably need to be replaced. First, make sure the sound is not on mute or at a very low volume. If the sound is not muted and no sound is produced, try plugging headphones into the computer. If the headphones work, this means the sound card is functioning properly and doesn't need to be replaced. At this point, the most likely cause is the speakers, which need to be replaced. See this guide to see how to replace the speakers.

I’m adding this comment as an owner of a Toshiba Satellite L505 laptop and issues with the battery.

After initial 12-cell OEM battery went through a decent lifespan, I tried a 9-cell third-party battery. After not very long, the Toshiba monitoring app alerted that the battery was nearing the end of its rechargeable life! So an acquaintance mentioned similar problems with his kids’ laptops after buying 3rd-party batteries, and suggested to buy an OEM (manufacturer battery). So I went to a Toshiba 6-cell battery (all they sold); now despite the smaller cell size (6), after using this Toshiba battery for less than a year the Toshiba monitoring app again stated the battery was nearing end of rechargeable life.

It should be noted this laptop is not heavily used but used or turned on for an hour or couple hours 3 - 4 times a month, so no high charge/discharge cycles or prolonged inactivity. So I’ve limped along now for awhile having to keep it plugged with the AC charger. Something definitely off.
