Laptop is on but no screen and no response to any actions
The computer is on, the fan blows, the wireless indicator is lit, but it does nothing. It charges, however, it doesn't indicate its charging. Stepnote 1502 less than a year old. If I could get something on screen, it would help. Plugged into Different monitor but still nothing but black screen.

Re: Laptop is on but no screen and no response to any...
It does not sound like inverter has failed because you are using the correct method to switch screens, if the hard drive indicator is flashing/blinking that seems ok too. latops are supposed to beep when there is hardware failure to give us engineers an idea of the problem, you haven't mentioned that, but i know there is hardware by the description. start by taking the ram out, this could be faulty or disslodged and the machine sounds like boot but no display, clean the contacts on the ram with a pencil eraser (they work best) and dust off the rubber with a dry clean cloth, make sure there is no build up of dust there the ram slots, if you have more than 1 ram module try them one at a time. see what happends

When you turn on the laptop and get a black screen, does it sound like the computer is still running(are any lights lit up etc) ? If so, then you possibly have a bad video display. I would highly recommend visiting a repair shop or contacting the manufacturer of our laptop for service repairs.
If the laptop is plugged up to any other display, or TV , unplug it and reboot.
If it does not sound/look like your laptop is actually turning on then you may have a power issue. You can try some of the following tips to see if it resolves your issue. -Leave the laptop charging for 10 minutes then try and turn it on. It may not be charged up enough. -Try a new power cable -Try a new battery -Try a different wall to charge the laptop.
The following applies to Acer Laptops. You did not specify the brand of laptop you had. If your laptop is not Acer, the specific keys mentioned may be different and you should adjust accordingly.
If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on. If pressing any key does not turn the display back on, check the following.... 1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level 2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display 3. Backlight might be turned off. Press Fn and F6 to turn on the backlight. 4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.
Because of the very high CPU Usage, the right side fan will run more then the left Fan. Left side fan is for the Power supply. For this exhaust problem, use the laptop cooling pad while using the laptop which will solve your problem.
Pardon for the quip on semantics, but thumping seems a bit... well... drastic. A rattle could indicate one thing and a constant/intermittent clicking (of sorts) indicates a different problem.
A kind of rattle or I suppose a 'throbbing' could indicate that your cd/dvd drive is out of balance (this would only be obvious if there were a disk in the drive and usually immediately apparent when trying to boot up), but this doesn't usually keep the computer from booting to a POST screen.
Another indication of this 'throbbing' could be that your cooling fan has lint or other debris lodged in it. This would definitley keep the computer from booting as several computers won't boot (desktops as well) unless some kind of rotation is recorded as coming off of that particular fan.
If this happens to be the case, I would recommend that the laptop be professionally cleaned as simply trying to use compressed air would just ram the debris in harder. So complete dis-assembly is the only way to get to the obstruction.
If the noise is more like a rattle (constant or intermittent) then there is a likelihood that your hard drive is about to completely fail. Again, this would be more identifiable within Windows as there is a new software alert that pops up warning you about such a failure.
Redundantly, this by itself wouldn't keep the computer from at least booting to a POST screen and possibly into some kind of error message.
The last thing I would recommend is to try powering the system up with the AC adapter alone and see if the same symptoms occur. If so, there is obviously more deeper routed issues. The worst being a catastrophic motherboard failure.
I believe that your problem is not the motherboard but the DC Power Jack that you plug the power source into. This is a regular problem I've faced with Gateways often. I now send them in on a regular basis to any one of several DC Powerjack Replacement vendors on eBay, who will offer a flat rate of around $80 dollars with return shipping. You will be responsible to pay the inbound shipping and I use parcel post as it's least expensive.
Go to ebay and in the search box type in DC Power Jack Repair and you'll get a big list. I cannot recommend a specific vendor here due to policy but I have never had a problem with any vendor for this problem yet.
I am also user of Acer Aspire laptop. When you on your system after 3 min just press FN+F6. I hope you will see your screen ON. IF not thats mean your monitor not working proper may be display problem. Just visit Acer serviec center. Thx
Try to plug in an external monitor on laptop to check if there is a problem with your LCD.
Plug in the external monitor then boot the computer. If still nothing happens try removing the battery and the adapter, let it rest for a minute then plug in only the adapter and try to boot up with out the battery.
thank you for your response....I'm using Vista and the power seems to be on but the screen is down. I have to hold the power button down for 10 seconds to shut down then turn it back on to restore the computer. It is a Toshiba A215-S5818
