Try removing the battery and starting it up. Dell batteries are notorious for developing a short that won't allow the machine to start. Then try starting with one or the other memory chip in.

Usually this is a battery or memory issue. For flashing light codes on your machine you can refer to Dell's support site.

My toshiba at200 table 10.1 wont turn on


1. When you press the power button to turn it on, do you see any thing on screen, like the toshiba boot up screen or something like that. Or is it completely blank (black color) always.

2. Can you see a faint image of your desktop (try to see it in dark place with flash light). This is important to confirm.

3. Also, when you press power button, do you see the LED lights on laptop blinking or solid green (which ones are in blinking/solid) and do hear any sound ? Or do you feel that your laptop doesnt even try to boot.

My hp laptop dv6305us screen is blank power light is on but screen is totally blank.


The DV6000 series of notebooks are known to have problematic motherboards. Try the below options:

1) Hold the power button down for 5 second and the machine should shutdown. Then power on again.

or

2) Flip the laptop over and switch the "lock" switch to "unlock". Then flip the release button to remove the battery for a few seconds. Put the battery back in and try to power the laptop on.

or

3) Power on the notebook like normal. Watch the Hard Drive activity light (the one that looks like 3 stacked plates), if the screen is blank and the activity light is solid or flashing, you know that the LCD screen is bad and needs to be replaced. If that light is not flashing then the problem is your motherboard and it needs to be replaced. Call HP and ask them if your model was part of a DV6000 series recall, if so your repair costs might be covered.

My computer turns on but the screen stays blank and the light near the caps lock button and scroll lock button flash on and off. i have tryd pressing the fn+f4 button like the book says but that doesn't...


If you go on to hp.com and enter computer model + Caps you should see a list of all the errors it could be. It is a rather long list....but in short it could been CPU, BIOS, MEMORY, GRAPHICS -problem issues.

I would bet you have flashed your BIOS and the computer power failed along in update process and there you got a BIOS update failure.

HI,
Do a power drain, this may cause by an electrical charge in the motherboard itself,Im Not really sure how it affects the display of the computer but this method usually fix such problem like that, First, removed the battery then unplugged the AC adapter the press and hold the power button or the ON/OFF button for at least 30 seconds then connect the power supply back to your computer then turn it back on, if nothing happens,there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...


Hope this will help...Your response is very much appreciated...

Hold the power button for 5 seconds or more - does it turn off properly? If so, can you turn it back on afterwards?

Take out the battery and unplug the power adaptor. Let it sit for a few minutes. Now try the power adaptor alone. If this works, try shutting down and running on battery again.
