Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. This is one of the most common problems with Toshiba laptops we deal with. Indications of laptop overheating problem: The keyboard and the bottom of your laptop are very hot when the laptop is working. The CPU fans are working all the time at maximum rotation speed and operate much louder than before. The laptop suddenly shuts down by itself without warning.

To determine what components are causing your issue, verify that lights on your hardware devices, such as the CD-ROM drive, are not on when the noise is being made. If you are only encountering excessive noise when a device is accessed, it is likely that the device is causing your issue. If the noise you are experiencing is occurring the entire time the computer is on, it could be any of the below devices.

Distinguish what device is causing the noise by reading through each of the below sections. CD-ROM, DVD or another disc drive CD-ROM and other disc drives may generate noises when the drive is accessed. Disc drive noise should be a soft whirling noise when the CD-ROM drive is accessed and only be generated when the CD-ROM is accessed. It is abnormal for a CD-ROM to experience any of the below symptoms.

There are several fans in computers that help provide ventilation to the computer's components. Below is a listing of the fans that may be causing noises in your computer. Case fans are fans commonly attached to the front or back of a computer. It is normal for most additional case fans to generate additional noise (usually a low hum). However, you should not expect to hear any clicking noise or high pitched noise from any of the case fans.

When this occurs, it is a good indication that the fan is failing or has already failed. Although not installed on all computers, some computer heat sinks may also contain a fan to help with keeping the processor cool. It is also not uncommon for a fan to go from quiet to loud while you're working on the laptop. Most computers and laptops will adjust the fan speeds when the processor is working more, or computer is getting too hot. You should only expect to hear a slight hum from the CPU fan; below are some issues that may cause additional noise from your CPU fan. See below power supply section. The computer hard drive is a common issue for additional noise. It is normal for a hard drive to produce noise. Normal noises you should expect to hear include a low humming or quiet whistling sound. Noises you should not expect to hear are repetitive clicking, very noticeable humming, knocking, or any hard thump. If any of these noises are experienced, it is recommended that the hard drive be looked at, or you replace the hard drive as it may be going bad.

Note: You will notice an increased volume of sound from a SCSI hard drive when it is compared to a standard IDE/EIDE hard drive. Note: If you have an SSD it should never make any noise.

If the fan within the power supply becomes bad or dirty, it can cause an excessive amount of noise. If an excessive amount of noise is coming from the fan next to where you plug your computer power cable into, it is likely that the power supply fan is failing or bad. We recommend that you first clean the fan by using compressed air to blow out any dust, dirt, or hair.
