Compaq Presario R4000 looses video and freezes after a while

My Compaq Presario R4000 looses video and freezes after a while. This has been happening for some time now . I had stored for about a year because of time constraints. When I turn it on initially (after resting for a few days) it works great for about half an hour then looses video. When I turn off using the power button and turn on again the same thing happens but in less time. This continues until eentually nothing comes up when I turn it on. When video is lost, the hard drive and fans continue running but no response from keyboard from keyboard when I press caps/num lock. I don't see any signs of overheating, the base is at normal temperature. Nothing happens when I tilt the screen -don't believe its a short.

The problem you describe can be caused by two different things. The two are not related to each other in any way.

The first, which is more common on desktop computers than laptop computers, is a thermal problem. The video chipset is overheating and causing a shutdown of the video. It is possible that this overheating is actually the cpu, but I don't think so, based on your description.

The second is the video power inverter chip. The power needed to keep the lcd screen lit up on a laptop is considerably more than what is needed to run the laptop itself. For this reason, a small power inverter chip is installed on laptops. It is usually found under the plastic bezal that surrounds the screen, and usually on the bottom. When this chip goes bad, the symptoms are as you have described.

Here's a couple things you can do before seeing a technician or teaching yourself to take apart your laptop. Plug in a different monitor; an external monitor and restart your computer. You should have a function option that will let you see two monitors at once. (that's the fn key, usually in the lower left of your keyboard). With two monitors showing exactly the same pictures, see if you can recreate your symptom.

If the problem is in the power inverter chip, the external monitor should remain on when the lcd monitor goes black.

If the problem is inside your computer (video or cpu overheating) then both monitors will go off.

good luck

I have a compaq presario r4000 will not boot up correctly


When you start it up, go to the BIOS option and select "peripheral" settings. I don't know which column its under but you want to turn the network adapter off. If that makes your Operating System come up working (And you may have to come up in SAFE mode the first time), then you can always go back and reset the BIOS to recognize the network adapter, or install a different one.

Presario r3000 too slow


I have a R3000 and after many years of usage many things happen and add to your hard drive. It can be a number of things from not enough hard drive space for your cache file to bad installed drivers.
I would suggest a full format and install using the backup disk that Compaq sent with the system. You should have the WinXP code on the bottom of the computer. This way you get a 100% clean system. You will have to reinstall any additional software such as MS Office or your virus scanner.
Hope this helps
