Mine is Toshiba Satellite u300-11v. I have it for the past 2 years. I never carried it anywhere. It is making huge grinding noise when starting it for the first time, now a days it is making noise even when starting it from hibernation. I don’t know exactly weather fan or hard drive makes noise. However i suspect the sound from the left side of the laptop. Please advice.

It’s easy to find out if the grinding noise comes from the hard drive or fan.

First of all, remove the hard drive and start the laptop with the hard drive removed. Now listen for the cooling fan. Make sure the fan actually spins. If the grinding noise is still there, you’ll have to replace the fan.

If the noise is gone when the hard drive is removed, it’s not the fan problem. Most likely you’ll have to replace the hard drive.

While playing songs, suddenly, sound on the right side internal speaker is dead but another -left side speaker is working, now only one speaker is producing sound. If I check it using headphone, sounds on both sides (left and right side) are coming. Please let me know what the reason it is.

Both channels in headphones are working and it means the laptop sound card is working correctly.

Most likely your problem is related to the right speaker failure. Apparently, the right speaker went bad and has to be replaced.

In order to replace the faulty speaker it’s necessary to disassemble the laptop, remove the top cover, unplug the faulty speaker from the motherboard and replace it with a new one.

I’m fixing my girlfriends Toshiba Portege A100 and the fan is dead is there anywhere online where I can order a new fan besides Toshiba (i.e. non genuine parts or second hand ). Thank you for your time.

I had to repair Toshiba Portege A100 only 2 times. First time I replaced the hard drive and second time I replaced the fan. That’s a lot of work, because you cannot access the fan from the bottom of the laptop or even if you remove the laptop keyboard. The fan is located on the bottom of the system board and you have to remove the board in oreder to replace the fan. You’ll be surprised, but I have created a guide for replacing the cooling fan on Toshiba Portege A100. The hardest part was finding a new fan. This model is not sold in the USA so I had to find an equivalent. I found that Toshiba Portege 3500 should work fine, and it did. That’s the same fan. Here’s a part number for Toshiba Portege 3500 fan: P000363930. You can search for this part number on eBay or just Google for it.
