When i start it, his fan turns while a few second and stop, nothing is happening neither the screen doesn´t display or bip. what can i do

sounds like its over heating,clean the fan out

if all fan are spin up.
see your RAM, maybe its broken.
a computer need a routine checking all RAM, if its not good, your computer will freeze.
try pull out and put it again. if its doesn't work. replace it.
PS. when you pull out your computer with all RAM pulled out and doesn't heard any BIP BIP BIP (BIOS POST CODE) noise. I can Assume your Mainbpard or ypur processor is broken. maybe its sound scary but its not. see for computer service center to help, they can give you good advice.

That would leave the processor ic, usually most motherboards do not include that.

This would indicate a video display card problem. Since the VGC-LT23E is an integrated system; this could be difficult to track down without professional intervention.

1. Check your power cord & adapter.
2. If its working then check the battery, reseat the battery & check.
3. If available then check with another battery
4. If no, then remove the battery & switch on the PC in AC mode.
5. Check if battery charging indication or AC power on indication is glowing. if not then need to change ur motherboard.
6. If indication is OK, but could not power ON then check ur RAM for any loose connection or dust. clean & reinstall.

May be there is a problem in the windows, but suppose it is not booting at all.

First Check once more your boot options from bios menu
Second If it still the same thing, extract your battery out of your laptop for 12 min, then try to power up your laptop pluging in your power cable(don't use your battery)
Third If it still not working, there must be a problem in your cooling fan, so check it, also check your motherboard & your graphics card (Most of this problems happens due to a problem in the computer cooling system in motherboard & graphics card)

Hope it works for you Christos

hello
you have installed wrong bios update
noting are to do now buy new motherboard

Maybe your graphics card is overheating, check the cooling fan over your graphics card and if it has sufficient power plugged into it.

lets try a few things bronx,

lets start by going over the beeps and lights. when you power the unit on. it should go Blue and stay blue. this means the unit is so far functioning correctly.

if your unit turns on lights up blue, then yellow , then red and stays red you have an issue

if you are experiencing the first scenario, press the power button till it goes red. which is standby mode.
then press button again till you hear two beeps, let go. make sure you have all your cables plugged in. this will send you to the diagnostic screen on the ps3 to select anyone of your options. since you are not getting a video display select the display settings and reset yours according to your type tv. if you are using a standard old school tellie, then its 480i, if you are on a plasma or lcd it would be 720p,1080i or 1080p. then you should be good from there


okay, if you are experiencing the second scenario its a much more severe issue. the GPU on the motherboard has gone bad, which is common on ps3s. if it is under warranty contact sony and they will send you out a refurb'd unit. if it is not under warranty there are a few good companies out on ebay that reflow or reball gpu chips on ps3s to repair this known issue.

since you are getting beeps and lights this is one of your scenarios. if you get no lights,no beeps then you got a bad Power Supply.

Good Luck!
