Put the CD in the CD-Rom and restart your laptop as it is booting keep pressing the F12 key and will bring up the boot priority just click on CD-ROM it will then continue to boot and you might see a screen saying press any key to boot from CD and it will boot from the cd

Hp pavilion dv2000 lights switch on but boot or


Hi

Thank you for your query

Please try the folowing

1) Remove ALL wires and then press and hold the power button in for approx 20 seconds

2) Plug everything back in and then rerty

This may sort the issue out however from what you are descrbing, if there is no boot or display it is highly likely the motherboard and/or the CPU is faulty

I would recommend that you book the PC into a reputable PC repair shop if the above does not work

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again

Keyboard and VGA port does not work,i think it's a motherboard


i think your board is dead you must wait 15 seconds to reboot your pc or you will over surge it with power my buddy did it to mine and blew up my graphics card your board might be dead but does it make a clicking sound when you try to start it or any beeps if not your board is dead you could try to clear the cmos just take out the round watch battry on the board for about 5 min and then put it back in and start it up but theree should be a jumper you can use to clear the cmos cmos is your pc's boot options you know when you hold the delete button and shows your boot options it will reset itself try that if nothing works your board is dead

BIOS corrupt after an upgrade, how can I load the factory settings of a laptop ZE5600


You need to "flash" the BIOS with a good file and then your computer should boot up for you.

HOW CAN I LOAD XP IN HP PAVILON DV 2910TX


Hello,

If you have the Win XP CD place it in the cdrom and boot the computer up. Make sure the bios has the CDROM as the first boot device and windows will automatically start the install when it boots up.

Wont boot up or start - cpu fan does spin but switches off


You seem to have a lot of hardware in there, so trying to remove some items to lighten the Power Load was a good idea - but maybe too late.

Check your Power Supply - I suspect that you will need around 550 Watts or more. If you can put in another Power Supply (after disconnecting as many drives etc as you can) see if the problem re-occurs.

If it does not, then your Power Supply is failing and will need to be replaced (with a 550 Watt or above PS Unit). I would personnally think that a 700 Watt unit would be ideal if it were my machine.

Yeah, I know you said you replaced the Power Supply but didn't say if everything was reconnected nor what size Power Supply Unit you put in.

Good luck.

Power switch


You could try searching for the manual for the motherboard, I have the same problem every time I disconnect a motherboard.

Sometimes it is printed on the motherboard in dead small writing which wire goes where.

Also usually motherboard manufacturers follow the "unofficial" standard io connectors.

+PLED -PLED +PSW -PSW NC NC NC NC
+HDD -HDD -RST +RST +SPK NC NC -SPK

Key:

PLED = Power LED/Message LED
HDD = Hard Drive LED
RST = Reset Switch
PSW = Power Switch
SPK = Speaker
NC = Not connected (sometimes not even there)

Note quite often the Reset switch is the reverse of everything else! (i.e. on most if the + is on the right the + is on the left for the Reset

The USB ones usually always follow the following standard

VCC -DATA +DATA GND NC (USB1)
VCC -DATA +DATA GND NC (USB2)

And usually one of the NC pins is no pin as some USB cables have that pin blanked out to ensure you connect them the right way. Note also with USB you start with the VCC then you go straight to negative data, then positive, then ground (again the - and + data bits, like the reset are in reverse of normal reading - the are right to left, not left to right!)

Finally if your not sure which cable is + and which is - the - ones are normally either black or white (most of them are white, except the speaker ones which are black - I presume that goes back to the colour scheme of red and black for positive and negative in audio equipment) and the + ones are normally some colour.
