    Compaq Presario R3000 power cord issue

    I took it down to the level specified ing the manual. This constitutes "ripping it apart". The correct way to do it. Good Luck!

    Compaq Presario R3000 power cord issue

    Hi Everyone! I am the guy that posted the manual and all my disassembly pictures. Just thought that I would give an update to the 18K+ people that have viewed this posting topic. The solder joints are bad in a lot of places. Two days ago, I plugged my headset into the R3000 for the first time...

    Compaq Presario R3000 power cord issue

    Everyone, I resoldered all 4 pins and added a bit of solder, for more strength. All four pins on mine were cold soldered. I am surprised it lasted 1.5 years. A good solder joint should be shiny, not dull. Excess flux can be cleaned off with rubbing alcohol. Rod

    Compaq Presario R3000 power cord issue

    Kas, Thank you for saying so. I do pride myself on being a very thorough electrical / electronics engineer and have not let any so called 'tech support' persons touch my hardware or software installations. As condition of my work with multiple employers, I have insisted that no individual...

    Compaq Presario R3000 power cord issue

    Everyone, Regarding JFrizzles last post, if you do this repair, it is a good idea to use a small bowl or container to hold the screws for each part disassembled. That way, you should have a good chance of getting everything back together using the correct fasteners. There are a LOT of screws to...

    Compaq Presario R3000 power cord issue

    J, Yes, there are screws from the top. You don't have to take the fans out. Take the whole motherboard out. See my posts on Aug 05. I have links to the manual, etc. The manual states exactly how to disasssemble the unit, althought you have to jump around in the manual a bit. I have also posted...

    Presario R3003 and 12v adaptor issue

    I think that 300W may not be enough, pure sine wave or not, with a bad battery. Does it work withe the battery removed? (I asked this previously) I could not find the specifications for any Kerio DC-DC converter online. Do you have a link, or detailed information. Rod

    Compaq Presario R3000 power cord issue

    I initially intended to change the connector, but the PC would not charge at all at one point. So I immediately took it apart and found that all four solder points were bad from the factory. I resoldered them and it is great now. Rod

    Presario R3003 and 12v adaptor issue

    You may be right, shut it down, pull the battery out and try it. My thinking is that the devices that you purchased may not be able to handle a dead battery and powering the PC. Assuming that your AC supply is 240V, the watts required is 240V x 1.25A = 300 watts, making the purchased inverter...

    Presario R3003 and 12v adaptor issue

    Rustie, Look at the posts about R3000 power cord issue. There is an issue involving the connector on the motherboard coming loose on this model. Vibration or movement (like driving the vehicle) can cause the motherboard connection to make/break. Mine started as an intermittent problem, then...

    Presario R3003 and 12v adaptor issue

    If it is R3000 series, it needs 18.5 volts, it won't work on 12V. If you are using an invverter, it should be 400 watts capacity. I run mine using a 400 watt 120V inverter in the car all the time.

    Compaq Presario R3000 power cord issue

    Phil, The bezel still snaps in, just is not as tight as it should be. I just can't pull on it. I never did anyway. I have posted pictures with my first entry. I hope this helps everyone out. There are 85 entrys for new power supply connectors for the R3000 on Ebay, so I am pretty sure that...

    Compaq Presario R3000 power cord issue

    Phil, I completed the repair. The factory solders were obviously "cold solders". All connection points were loose, and dull gray in color. Also, the sound on / off switch on the right side of the machine stopped working about 6 months ago, and the switch solder connection had come off the...
