The front panel of the computer contains the power and reset buttons, power and activity LEDs for the hard drive, speaker, external USB connectors. It is connected with several cables to the motherboard.
It is necessary
- - screwdriver;
- - pliers;
- - tweezers;
- - a damaged flash drive.
Instructions
Step 1
Power off the computer and all peripheral devices. Remove the left cover from the system unit and place it on its side. Locate the front panel connector group on the motherboard.
Step 2
Straighten all front panel cables. Locate the POWER SW and RESET SW connectors. Connect them to the corresponding pin groups on the motherboard. If there are no designations on the board itself, you will have to find an illustration explaining the purpose of the contacts in the instructions (there is no standard for their location, and each manufacturer places them differently). You can connect these connectors in any polarity.
Step 3
Supply power to the computer and monitor. Make sure the power and reset buttons are working properly, then de-energize both devices again. If you are satisfied that the speaker, LEDs, and front USB connectors will not work, you can complete the connection here.
Step 4
If you want the front panel to function fully, find cables with HDD LED and POWER LED connectors, which also connect to the corresponding groups of contacts on the motherboard, but this time, observing the polarity. Turn on the computer and make sure that the first LED is on when the hard drive is active, and the second is always on. If one of them does not work, with the machine de-energized, reverse the polarity of the corresponding connector.
Step 5
At the next stage, you will need a control device - a damaged USB flash drive, which you do not mind burning with a voltage of reverse polarity. She must have a working LED. Near the front panel comb, locate two more small groups of pins for the front USB connectors. Find out from the instructions for the board the location of the contacts (Power, D, D-, GND) on these combs. If the pins on the connectors on the front panel cables are marked in the same order as on the board, be sure to connect the connector in the correct direction. If not, rearrange some of the contacts in accordance with the location of the pins on the board. Sometimes on the front panel cables, instead of solid four-pin connectors, there are four single-pin connectors - they are the easiest to rearrange. Avoid short circuits.
Step 6
After turning on the computer, connect the damaged USB flash drive first to one connector on the front panel and then to the other. In both cases, the LED should be lit on it. If so, plug in a working USB stick and make sure it works. If not, with the machine de-energized, swap the D and D- pins (but never Power and GND). Turn on your computer and make sure the flash drives are now working. Close it and stand upright again.
