HP Notebook Hard Disk Sound Should be How to Solve

HP laptop repair center, often the customer reaction HP laptop hard drive in the process, sometimes the sound, and thus there is no way to work properly, actually this is not a fault, is a normal phenomenon, so how should we resolve this annoying The sound of it, the main method is as follows:

HP notebook hard drive abnormal sound failure analysis:

Hard work needs stable voltage and current supply, if the voltage is unstable or inadequate power supply current, it will seek a difficult, hard, "Kaka" ringing, or can not find the hard disk or data reading difficulties , may also be manifested as a hard disk suddenly lost in the work process, the data can not be read, etc..

Both cases we use computer switching power supply power shortage or failure to appear above. For the power supply of +5 V and +12 V voltage instability phenomenon, we can use the multimeter test to judge. Too high and too low will not work, generally within 10% fluctuations can be considered to be the normal situation. Current lack for power, we can calculate how much their host's hard drive, CD-ROM drive and related configuration with its full load of power, compared with the Power switch. Under normal circumstances, the power supply power should be greater than the various components of the 10% of the sum of the maximum power, rather than make the two are equal.

Laptop repair engineer experience, there is a situation that is hard to their own problems, may chip failure, may also be damage to the motor, and then the magnetic arm fracture. But here said the hard drive suddenly loud "Kaka" neither insufficient power supply, nor is it due to damage to the hard disk controller chip, but a hard circuit boards and hard disk magnetic arm-powered interface part due to poor contact . The hard drive circuit board powered phase plate body part is not pin or flexible cable, instead of using a crimping method, because the hard disk is used for a long time, coupled with poor working environment, the interface board tinned layer oxidation, disc body spring leaf oxidation, resulting in poor contact between the two, resulting in unstable magnetic arm Seeker motor powered, and seek abnormal, the hard drive does not work.

Troubleshooting:

The solution is very simple, four screws to disassemble the fixed circuit board, remove the board, up to pick up the board, there will be two rows of spring in the interface side of the board, we need to be careful with water sandpaper each a spring piece contacts polished bright. While the corresponding contacts of the circuit board also polished bright, then the circuit board as it back can.

Laptop repair engineers recommended: because of the rise of the price of today's notebook hard drive, if you buy a laptop hard drive to spend a lot of money, if you have encountered more than annoying hard abnormal sound, try the above method.
