    Default Compaq Presario C500 assist please.....


    I have had this laptop for nearly 5years with no trouble at everything. Abruptly I remarked my poweradaptor acquiring warm at the end inserted into the machine and thebattery was not charging. It finially reached zero and the laptopdied. I purchased a novel power lead and attempted to do an overnightcharge.


    The battery charge red light remainedwith for nearly 8 hours and then started to flash as if the level wascritical. I switched the machine with and it worked alright for about3 minutes then it died again. I presume that my battery has expiredand have ordered a novel one.


    Only to fulfill my curiosity while cansomebody please confirm that this specific model will not operate ifthe battery has no charge/is faulty or has been separated fully andthe machine only has a power lead adaptor like the single source ofsupply.

    Really had one of these suckers in.... I have never arrive throughout a laptop that does not work if no battery is present. It should work and proceed to work.

    Only make certain when you purchase a universal adapter or something, that the Voltages and Amps are exactly the same.... you can still acquire an adapter that has a higher amperage.... but the volts however must be identical.... otherwise I have laptops tend to go poof later awhile.

    Forgive me for doubting you but I have only had a guy to my house who applied to work for HP. He took on him suitable power adaptor and confirmed the machine will not operate if battery is absent or no longer working. Seemingly the adaptor is a battery charger and not a power source. This specific model easily does not operate through a power source just...must be through a working battery. He installed a novel battery and the laptop is now charging up and working alright whilst doing so.

    That is ok.... I have my doubts that the hp guy experience completely what he is talking about either.
    Personally I would tell that if that is the case, there is something wrong with the power control within the laptop itself.. you could call this a regulator. It is actually not everything that different from anything else that applies a 2 power sources, the system determines when to charge the battery and when to run off power, or both.

    If the regulator fries, it may be stuck running off the battery, forever attempting to hold it charged, this would even explain why your battery went poof and instead working. Later including managed countless laptops from only about anything in the past nearly 20 years, I have not watched a single one that required a battery to be present for it to run off the household power. while I do not recommend it like the battery works like a voltage regulator as well.

    More frequent then not, many of the manufacturers such like hp/dell/compaq/etc will spew garbage juonlyst so they don't have to admit that it may be another problem, specially if they can ensure that they have made few kind of a sale. In the end, do not be at everything wondered if this novel battery ends up disintegrating much sooner then you may care to enjoy.

    Thanks for the input. Fortunately the guy who called round is a friend of a friend thus no charge for 'problem diagnosis' and had a novel battery at cost. The old battery is definitely dead like we examined it in another machine and it rejected to charge up...Time will tell about the novel battery lasting. Thanks again for your comments..I agree that such problems are an ideal opportunity to rip people off and may be I have been stitched up....we will watch.

    Considerably so long like your working.... I only wish compaq would have supplied few better technical specifications with it... because it's kinda throwing me of that the power adapter would not power your machine without the battery.... it only does not create sense to me...

    A battery at cost is great... and including had the trouble resolved at no charge. also better.... allows hope it last longer.... but I have my theories. Can not actually tell anything for sure without ever appearing at it myself.

    You were quite right my friend. I plugged the novel battery in and left it for two hours. When I returned it displayed a 74% charge. The battery level dropped and dropped also while the laptop displayed it as charging with the HP meter. It finally reached 0% and the machine switched itself off again.

    Evidently no power is reaching the machine/battery when a charger is plugged in and I have attempted a pair which I experience are the right ones. Will acquire it examined out by a local computer shop, wondering if it is the jack socket which is faulty or perhaps a link to the motherboard. At least it remained with long plenty for me to copy the wife's Christmas Card list which is everything she was bothered about.

    Hello again,
    Brought my laptop into town and had it evaluated by three different firms everything on the same diagnosis...the power board has blown and no charge being received to either battery or PC. Bearing in mind the age of the thing I have rejected, transferred all my files to disc. Will attempt and sell the battery I only purchased and as well the 4Gb of RAM. Hard drive just 80Gb and contains much valued information thus I will destroy it. Thanks again for your advice
