Compaq Presario R4000 Won't Turn On

Thanks to learning a bit from your site, I tried to systematically find out what was wrong. at 18.5volts but still know ‘led' on! Right now, I'm having a problem where when I try to turn the screen on, the screen remains blank, and the computer beeps twice quickly before resetting. I needed to replace the hinges, and i was looking for something that could help to open the computer. http://mffonline.com/compaq-presario/compaq-presario-r4000-boot-error.php

IBM ThinkPad G40 2388 Notebook My Compaq died.... instead of giving 18.5 volt that the laptop required it was giving only 14 volts. The Compaq/HP CQ, or G 60/70 series is known for shorting out one day and not working ever again. The laptop can play CDs and DVDs, so most likely there is nothing wrong with the optical drive or the motherboard controller. internet

Try replacing memory with a known good module. I need a fix for it.

solved Old Packard Bell Legend Synera. the only way I get mine to work is by turning it off and on, taking out the battery while its on and then sooner or later it will turn on. Any suggestions? I took the laptop apart, blew dry all the parts, and put them back together.

I am going to leave the batteries out of the Compaq for a few more days just to see. http://www.tomshardware.com/forum/53111-2-compaq-r4000-boot-faulty-hard-drive Main Sections Technology News Reviews Features Product Finder Downloads Drivers Community TechSpot Forums Today's Posts Ask a Question News & Comments Useful Resources Best of the Best Must Reads Trending Now ive been trying to see if it works with external monitor but i havent figured out exactly how that works. thanks in advance for any help!

Do you know if you have two RAM modules installed? http://mffonline.com/compaq-presario/can-a-compaq-presario-433.php I try to reaseating RAM , harddrive and battrey, (like hp web site said) but stil not working.

your site helped me more than you could imagine, i work in the it industry but for another company other than hp and i just needed to see the instructions and It can be a memory related problem. my laptop is COMPAQ PRESARIO X1000. My preceding comment was hasty.

Herb Krakau April 18, 2007 | My daughter's HP Pavilion zt1290 had a failed solder joint where one of the pins of the ac adapter connector goes into the motherboard. I want to take apart the keyboard and check that specific key. From your description I would say that you’ll have to replace the screen. check my blog what happens is over time, the little plastic piece that covers the voltage converter slides over.

Faulty ram can lead to harddisk troubles, read/write errors, but I don't think it will kill a disk. When I try to turn it on, all the blue lights come on but nothing happens--screen is black. It's possible one of the memory slots is bad. and i can always just get a monitor for it anyway if external works.

Maybe one memory slot on the motherboard is defective. Do you know that you can buy a new keyboard for Pavilion ZE5400 series for about $30 here? I would rather expect bad memory to be cause of your posting/booting troubles, since your screen stays black, than the harddisk, which is not involved in the posting. if anyone has any further suggestions on this issue…I'll still try the Toshiba utility; thanks alot for adding it to the Resources page.

If I hit the power button, the power led flashes and so does one of the volume led’s next to it. 1. Make sure the wireless connection is not disabled. I need to take the bottom off i have taking all the screws out and it still want come off i need to solder the ac connection back together bert December Click to expand...

it's not reading any incoming power. I've tried locating a loose connection to the screen by disassembling my laptop. Result: Fan starts up for 5 seconds or so, and turns off. all you have to do is take apart the monitor and slide the piece back over and its fixed.

While I need to read my USB (Saver 512 Mbyte), I have to restart the Laptop every time. The Fan turns on for about 3 seconds but then it goes off and the power light blinks and the monitor won't turn on. I have to restart to start it working again. Join the community here.

Get maintenance and service guide. If you have two memory modules installed, test the laptop with each module separately.
