When i switch the laptop, i hear a knocking sound from hard disk and the computer displays non - system disk or error disk plz help

Good Day Kawindwe!

I am sorry but I think the hard disk is on its last leg. A knocking sounds is the first symptoms of faulty hard disk. It is better to replace it.

The non-system disk error is displayed when the CMOS BIOS failed to detect the hard disk.

There is a small chances of making your hard disk work again. It worked for me before maybe it might work with you too.

First, turn off your Laptop. Remove the power supply adaptor from your Laptop. Remove the battery. Press and hold the power on button for at least 5 seconds to discharge remaining volts on your unit. After awhile, return the battery, plug in the power supply adaptor and turn on Laptop. See if that recognize again your hard disk.

If the first did not fix it, try this one. Turn off your Laptop. Disconnect your hard disk and then reseat the connectors properly. Then, turn on your device. Did that fix your problem?

Kawindwe, in case that fixed it, I recommend you back up your files cause the hard disk will not last that long.

My Acer 5315 laptop (two years old) will suddenly not power on. The amber light is on when the AC power is plugged in but the other never comes on. I have used the Acer power reset procedure as well and...

ok, well. If you are sure at least one of the power supplies is functional and or one of the batteries is functional then the problem is the power circuit on the motherboard. Either the on / off button is shorting or there is a diode or rectifier problem on the motherboard itself. If the problem is just the AC supply and you are positive at least one of the power supplies you are trying is functional but the batteries are dead from not being charged then it could, and most commonly is, the actual plug on the laptop and it will need to be replaced. My experience with older Acer computers is that plug gets loose and does this or the plug on the power supply shorts. I don't know why but it is almost always one of those two things.

Child has plugged in laptop extension by mistake and now it won`t turn on,is it repairable as 120 photo files are on it

You could try removing the drive from its housing then plug it into a working pc's secondary hard disk slot, it may be just the casings's power supply which burned out. Alternatilvely buy a usb to ide or sata lead and plug the drive into an old pc power supply. then plug into a working pc via usb.

Hard disk not detected sometimes

I can think of 3 possible causes to your problem:

1. Faulty cable - try replacing the cable by borrowing a working cable from a friend. If this solves the problem then you need to buy a new cable

2. Lack of power - some USB drives especially those for high capacity drives require extra power aside from that provided by USB. If you do not have a separate power leading to your drive, check if there is a separate power slot and run a cable from it to your outlet/USB slot. Just make sure that the voltage levels are correct.

3. USB Slot - some laptops' USB slots do not produce power enough to drive a hard disk. Other devices may work (e.g. keyboards, mouse) but not hard drives. Try to use another slot in your laptop. If this works, remember to use the same slot next time.

Hope this helps.

My seagate 250 GB hard disk is not being detected, no lights, pls help me!!

First, try plugging it in to another usb slot.

If it still does not work, plug in another device to the same usb slot. If it does not work also, there is a problem with your usb slot, and you can buy an extra usb slot.

or, if the other device works, try unplugging and taking out all the power supply for your desktop/laptop. Then, after 20 minutes, plug them back in and then plug in your hard drive, then turn on your computer.

Hope this helps, leave a comment on what happened ^_^
