Screen will not come on hard drive light no light checked power supply is ok

This means power supply is OK. Simply check the boot order in the bios settings. if ok, then boot from a bootable cd. if not, correct the booting order making sure that the hard drive drive c: is2nd after CD.

check the power cables frm the smps connecting the motherboard and cd/dvd drive ..... also reseat the hard drive

For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!

Try removing the battery and unplugging machine. There may be a reset button (look on bottom of computer). Reset. Plug in and try again.

Make sure that your power supply is ok, I mean to say that check the connction. If it is ok then check that you are giving the actual power input to your hard drive. Don't connct the hard drive again. First check the power supply to the wall is having the same out put that required by the hard drive as input. Let me know the result.

Hi
did you updated the bios before this problem ?
do you hear any beep ?
did you add a new hardwarw to your laptop?
answers for this will help to solving this isue

Thank you for your reply.

I have solved the problem with local help.

Printed installation manual of Seagate 500 GB eSATA external hard drive has not properly mentioned how to use power on/off switch once connected to mains. I could get local help, who has already used the device. On/Off switch to be pressed for few seconds after mains connected, sometimes it comes automatically once power is on and USB cable pluged to the USB port of PC if power supply is ok. There is no indicator for the power supply (before device glows) after connected to the mains. I was in confusion whether power supply is ok or not.

Finally, It was found that the problem was with mains power supply and I have changed the power socket and adapter.

I can sell you a power supply if interested but if you get a red light the power supply is most likely still good. You may need a new motherboard.

try to disable your eithernet card in bios and see if you still get the error.
