I have a Toshiba Satellite L775d-s7332 17.3" laptop. The old battery (Model: PA3817U-1BRS) is bad, but when plugged in, the laptop turns on but not charge. I bought a new battery same model (aftermarket) and tried it but the battery light flashes about every 5 second. I return the new battery and bought another 1 and same results.  The laptop works fine with only charger and no battery or with charger and old bad battery. The latest BIOS on the laptop is installed version 1.50.  I can't downgrade the BIOS because the laptop wouldn't allow me since it does not see the battery. Any suggestions?

I have a gateway MS2285  (NV53 Series) laptop. It makes an annoying beep when the charger plug in. There is no setting in the Bios to turn off the beep. I also tried to mute the system volume but it only allow me to lower the overall volume. There is not beeping sound when the volume is muted but that is only a temporary solution. Any suggestions?

Power down the computer and remove the power cord. Remove the battery. Hold the power button down for 30 seconds. Replace the battery. Attach your power cord and boot. Does the light still flash? This could be a fault in the charging circuit.

Thank you for your reply. I tried the reset the laptop by power down it and remove battery and power cord and hold down the power button for over 1 minute but it does not help. I agree with you that it could be the charging circuit. I not too long start repairing laptops, i'll try to do some testing on the motherboard. Any help with charging circuit schematic  or any other advice will be appreciate.

Unfortunately I do not believe service manuals or schematics are easy to find for Toshibas. You will need to do a web search.

Windows 7.

  1. Right click on the sound icon down by the clock.
  2. Select "Playback Devices"
  3. Click on the "Playback" tab if it is not already selected.
  4. Then click on the speakers.
  5. Select properties in the bottom right.
  6. Click on the "Levels" tab.
  7. Click the speaker icon under "PC Speaker" to mute it.

That's it. No more annoying beep. Note that you could lower the volume in step 7 rather than muting it if you just want it quieter.
