Re: Cannot Switch On!

There are a couple of things that you can try. plug in AC adaptor, then press the Power button again, if it work, There might be a problem with the battery pack. Try using a replacement battery pack of the same type.

if it not work, motherboard problem, there is some fuse protection is burn. you may consoder sending it back for repair. hope this helps.

Power on but nothing is diplayed on toshiba l500

If you still get lights on the edge of the laptop & you can hear the fan spinning and harddisk clicking a bit but nothing at all is appearing on the display then it's either the screen or the power inverter that have gone. Either way it's not really something you can do yourself, take it to a technician to sort out. If you are not getting any lights, fan or clicking sound then it is a power issue - the LED doesn't necessarily mean that the power supply is ok. Again, not much you can do yourself, take it to an expert.
there is another way as well for running the machine again, and for that you have to do this. First, unplug it from the power cord and then take the battery out, as you complete with this press the power button for few times, for example you can even hold it for 30 seconds or so, then see if it fires up.

Sometimes that helps flush out any little bits of electricity/static that may have built up. And the after sometime try to boot the machine and see what happens.

Together with this, you may would like to remove the memory panel at the base and take out the BIOS battery to reset the bios, then place it back in. If your BIOS is someway despoiled this will get rid of the difficulty.

Power light comes on but nothing happens

What type of laptop? What operating system?

Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

Hi, I have bought this dell vostro 1015 laptop one and half year ago. Day before yesterday my windows XP hanged and I was unable to shut down. So I pressed power on button for few seconds to switch off...

It sounds like your hard drive has gone bad. As this is a laptop you can try to reseat the hard drive, if that does not help then it might be a case of hard drive crash.

Year old advent netbook 4211b will not turn on,

When you press power button press F1 or F2 or "del" key if you can see bios screen then you not need to refix RAM memory or reset bios.
IF you can see bios screen then lake sure harddisk is detected and SATA is disable then save settings and exit.
Also when you power up press F8 key if you able to see safe mode and other menu then you have change screen resolution enter in enable vga mode.
Then open control panel and display then change scree resolution to 1024*768.
Then apply and ok.
But if you can't see bios screen or nothing in dispaly then you have to refix RAM memory .
Check in back side there is 1 plate open it then refix RAM memory.
If still not get display then open back cover of laptop then find motherbord on it then pull cmos cell for 10 minutes so all settings go to defaults then again refix cmos cell then check.

Let me know if you need more assistance.

When I press power button, only power button is lit green solid and nothing else happens...nothing on the screen...all black. No sound codes. Tried external monitor...nothing. CPU fan keeps running....

yes its motherboard. GPU has failed. Most likely you'll need to get your motherboard Reballed or Reflowed. I have found some reasonable business partners that do this service through ebay. usually runs 80-140 to get fixed. good luck!

Power Issue

sounds suspiciosly like your chord fitting is damaged(loose wires at connection)and shorting.if possible try a friends power supply with same connecter type before renewing cos could be faulty(loose)connection at pc(inside)constant pushing and pulling of connections often causes 1. loose split or disconnected wires at male connection or 2.loose pins on motherboard female connection or broken housing (not difficult to repair)more difficult to find out how to get to internal connection.
