Keys or Keyboard Not Working
The Keys of the laptop won't respond, sometimes double type characters, stick or appear to be broken or missing.
Keys are Sticking
Keys are continuing to add unwanted characters as if pressed for an extended period of time or will not respond when pressed. Use a can of compressed air under keys to potentially remove large obstructions. If this fails gently pop keys out of their seating and gently wipe the underside of the key and the keyboard underneath it with a cotton swab and isopropyl alcohol.

Fan is Making More Noise Than Normal
If the fan is consistently making more noise than normal.
If the fan for your Acer Aspire v5 571P-6609 is making much more noise than usual, you can either use a small handheld vacuum on the gentle setting or a small can of compressed air to help rid the fan of dust, as demonstrated here.
Too Much Load
The more of a computer's resources are in use, the more heat it will produce which requires higher fan speeds to cool. Reducing the number of programs and applications running on your laptop could reduce fan noise.
Alternatively, you can upgrade your fan to handle a greater load. See [this guide] to replace your fan.
Alternatively, your fan may be compensating for improper ventilation. It is best to set laptops on flat, clear surfaces that will not block the vents.
