Either the power supply is putting out too low voltage or the power jack is bad.Try moving the ac adapter tip around while its starting up to see if it keeps it running or shuts it off.If it makes no difference try another ac adapter that does work for sure and see if thats the problem.If neither approach works,then the HDD may be seizing or one of the ram sticks may be bad.Some sort of hardware conflict can cause shut downs.You would have to take the bootstrap approach to narrow it down to one pacific component.
My name is ArmyMason, might I suggest that you do a system restore to take your computer back to a date the computer was working correctly. Click on start, all programs, Accessories, system tools and click on System Restore. Tell it to restore and choose a date on the calendar. If this doesn't resolve the issue run Anti virus to see if your computer is infected. If this doesnt help please consider using our Premium service.
1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on
Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.
It's probably the inverter for the LCD, it's located at the base of the display you need to open the top panel and check the connections to the inverter board. Please be careful not to get zaped there is several hundred volts at the output ! , unplug the laptop, remove the battery, remove the 4 screws around the display and carefuly pry the front bezel off. you'll see the inverter board at the base of the display , remove the connectors one at a time and reconnect them. This may help to brighten the display. Also try pressing the Fn key and the F8 key to adjust the brightness, if this dosn't help you'll need to get a new inverter ( around 20.00 bucks on ebay) and replace it.
Well if u have the same exact one as myself.
The wireless button is on the front right near the corner. above it and on the corner is the wireless symbol. If its working it should be lit blue. push it and see if it lights up blue for a few seconds. You should get a wireless connection confirmation on the screen.
remove battery plug in power...see what happens ...nothing happens press and hold power button until you hear response(shut down)press power as usual to boot.if it doesnt work first time try a few times more remember to keep power button pressed to shut down.
There is a mechanical problem with the R3000 wireless button and volume-down button where they seem to push fine but are in fact failing to make electrical contact. I know of two work-arounds. * Try pushing the button with a capped pen, gently at first, and then with increasing pressure. (Not so hard you break the plastic, please!) I suspect this gives the buttons just enough extra "oomph" that contact is established. OR * Push up on the battery compartment while pressing the buttons. If the battery is in, you can acheive this same effect by putting your laptop on a table and popping up the screen, then applying downwards pressure on that corner of the laptop body while pushing the button. I suspect this aligns things properly so that the button is able to depress just a hair further.
You may even find that these actions "loosen things up" enough to cause the buttons to work like new for a little while. I hope this works for anyone reading this!
It sounds like you have fried motherboard. If that's the case, you have to get it serviced by a place your manufacturer recommends. Sometimes the cost can be greater than just buying a new laptop, so shop around and see what you can find price-wise.
