Im having trouble getting my laptop to turn on. I can hear it running but the screen is just blank. I was using it on sunday and it worked ok but then when i come to use it on monday it just wouldnt work. I left it last night to charge the battery up incase that was the problem but its still not coming on today. Does anyone know what could be causing this?

Do you have a monitor you can plug it into. If the picture comes up on your monitor then the laptop screen is the likely cause, whether its a connector, a wire or the screen itself is the more interesting thing to try and find out.

Hi nicky with most laptops. Sometimes the screen backlight goes but please try this before it comes to that. There should be a button usually the Fkeys (i.e. F4,F5) check to see if there is one with a Screen and then press FN - say F7 (but the one that has the screen) This is also a usual joke where someone does this to be a pain. But if nothing happens then it may be the screen backlight has gone. If the computer still powers up as you say maybe try and find someone with a monitor or if you have an LCD tv try and see if it connects to that and you can actually get some sort of picture. If all else fails see (Neil) The DR he may have more better advice as it might be that the computer power ups but thats it.

P.S. If this is too technical for you im sorry but i hope this helps.

Regards Lee.

Ive just tried connecting it to a monitor but nothing happened. Also tried turning the brightness up but that didnt alter anything either. Feel lost without it lol

It sounds as though its just the fan running actually.

Its prbably crashed, Hold the start button in until it reboots

ouch id take up to the dr. Can i ask what model of laptop it is ? If its an acer and its just the fan its the usual sign the motherboard inside has gone. Usually to over heating. But to be sure take it the dr;s shop or see if mark can have a look for you

Its a HP 6735s i think. When i was using it on sunday it seemed hot as it had been running for a while and then the battery ran out so i left it. I just hope it hasnt overheated and damaged it.
Will try the start button in a minute. Fingers crossed.

I switch it off take out battery leave for a few minutes it normally boots up

No still no luck
Only thing i have come across is the caps lock light flashing and noticed it was five times. Judging by the link it is a general system board failure.

Unable to PM TheDr as his PMs are over the limit.

nicky ask Mark/Boss to look at it for you he said the other day he will help people if he can for free

if you can't get hold of the doc, message mark

turn on the computer and put a light up against the screen if you can see anything in the back ground then your back light has gone simple way of checking ,also do the lights on the front come on ie battery light and hard drive light

Ive just been speaking to Niki on the phone, there is a bit more to this and its giving 5 flashing pulses from the Capslock, which means a Board Problem.

Niki done well researching that part, but the laptop is now 4yrs old and is probably beyond economic repair.

Left her with a couple of options to mull over.

So its a know HP Problem.

no worries hope all ends well

Looks like the laptop is beyond repair and judging by google it seems to have happened a lot with this model. Best get saving up for a new one.
Thanks for everyones help

Just before you use it as a paperweight, try removing the RAM from the laptop and then try turning it on. If the caps lock flashes differently, or beeps occur, then you may only have faulty RAM, not a faulty board.

Unfortunately with laptops, not a lot can be replaced unlike desktops. The only components you can replace are; RAM, HDD and in some unlikely cases, CPUs. Graphics cards replacements on laptops are only for the ultra gaming end of the scale.

HP Laptops have to be one of the least reliable laptops in the history of laptop-kind.

If taking the RAM out sees no change, then take your hard drive out (As it'll have all of your stuff on it) then you can either ebay it as Spares or Repair, or have yourself a doorstop.

Good Luck!

Try this, it worked for mine.

START BUTTON AND F8 PRESS AND HOLD FOR A WHILE, KEEP DOING IT AND IT SHOULD BOOT UP EVENTUALLY.
