    Acer aspire m3710 one long beeping

    Must be a few years old? Sounds like the on-board battery. Remove the side and locate it, change it and the machine should start. It's usually a 2032 battery.
    Once changed, you may have to go into BIOS and reset the time. Usually when the computer starts from the very beginning press delete and this should bring up the BIOS screen, then change the date and time, save settings and it should boot up with no problems. A friend had exactly the same problem with a different machine.

    1; Try running with no main battery first. (batteries are short lived)
    2: try a new power pack.? (wall to PC)
    3: ;make sure the power pack jack at PC edge when wiggled does not cause screen to drop out. (bad connection there)
    4: bad LCD inverter. (if separate from main screen)
    5: stuck key on keyboard.
    6: As you turn it back on tap the F10 key. This will load BIOS setup utility.
    Press F9 to load defaults.
    Press F10 to save and exit.
    7:overheating, it can do that fast if the CPU heat sing falls off.
    or goes loose with no thermal compound working there,
    or full of dust bunnies. the fan must blow and most cool the pc
    and not have its vents blocked, clean it. is cure.

    Ram beep but no display bios jumper is clear stat bios jumper is normal then no start machine

    Please see this as reference

    Continuous long beeps-RAM error
    2 short beeps- BIOS error
    1 long and 8 short beeps- Display Card error
    1 long beep after few seconds 2 short beeps-FDC error
    1 long beep after few seconds 1 short beeps-FDC is Ok
    1 long beep and 2 short beeps-Display Card Error

    Most probable cause is Ram memory, please try removing modules and reinserting, also try using alternately just one of them to determine which one is defective.

    Black screen please help

    the beeps are called BIOS BEEP codes. and is telling you what is wrong.
    does run with no battery removed
    do the BIOS screens work they MUST at all time. power on ,hotkeyed.
    is the fan running
    its old right,
    like an old car that will not start do you buy a new car?
    or buy a new battery? hummmmmmmm
    ever heard of a tech>/? those folks that diagnosis things?

    tried taking battery out, but failed to say it would not run only on the power pack. take it out and leave it out for now... be wise.

    so the HP logo works every-time you never said that yes./no.??
    if yes the BIOS is ok. see? means the brain works the Ram is not dead and if you had pressed the BIOS hot key F1,F1, Esc, F10
    what ever it is , it tells you what at boot in text. if you look there.
    if it stalls with good bios that means.
    bad HDD or bad OS.
    IF YOU Press that, at power on ,it goes to restore mode.
    (means reload windows)

    oops HP retired this PC

    that means in English clear, its NOT SUPPORTED NOW.
    no books no software no updates no NUTTN
    No anything, !

    now you know why mom dump it.?
    LOL !!!!

    its a dead fish.
    or FORD, found on road dead. LT.

    why not report the beep codes
    clear and accurately,??????????????????????

    run the LT with no battery and level it like that till cured.

    then, replace the COIN cell, no laptop this old has good 3vdc coin cell, impossible I bet.
    if the cell dies, as all do in 5 -10 years.
    the PC beeps with CMOS clock, NVRAM errors.
    the battery size of a coin, runs the Real time clock and the
    CMOS memory bank for the BIOS settings.
    if the coin goes dead BIOS GOES NUTS ANT TIME/DATE goes NUTS.
    if the beep codes say the HDD dont boot that usually means HDD is dead.
    the trouble with beep codes are that there are many BIOS used
    and many codes used. some are impossible to find.
    beeps are now gone we flash LED codes now.

    this is DT coin, LT is warped in plastic and 2 wires. see the COIN?

    1 long , 1 short, ? is COIN dead.

    note the black hole OF BIOS code HELL here, its a bad place to be.
    for sure.
    one other test is go to BIOS page.
    see that time/date, year, settings. if way off the COIN is dead.
    learn to that a 1/2 dead coin can work now, then file and 1 hour later work, that is how batteries fail. they go MARGINAL sometimes.

    My fitjutsu siemens amilo li 3710 laptop does not turn on

    It sounds like a hardware error probably to do with the motherboard, powerboard or the BIOS.
    First of all take the battery out and boot it on AC power only, as the computer starts up hit F2, enter the BIOS utility and set the BIOS to default settings, hit F10, save and exit the bios.
    Let the computer start up without the battery in the shut down.
    Reinsert the battery and see if the machine powers up and starts to charge the battery.
    If the symptoms are still the same after setting the BIOS to defaults then i suggest that you take advantage of Fujitsu's manufacturers warranty and sent the laptop to be looked at.
    Fujitsu's customer service techs are very helpful and they will take you through some troubleshooting first before they book the machine in for repair.
    A courier service will usually pick the laptop up from your home and usually takes around a week for the laptop to be returned to you.

    Good luck.

    PC start directly

    Explain what you mean when you say 'when i open the pc from main switch'.
    Also, something you should try is updating the CMOS, or in other words flashing the BIOS firmware. Go to your motherboards manufacturers website and see if there are any BIOS updates for it.

    This isn't something as simple as a dead / broken / malfuctioning battery is it ? Try removing your battery, plugging the laptop into the mains and running it idle. The Bios update you found may have been a coincedence...

    It appears that the Bios can't remember the settings and loads default settings each time it starts. Please replace the battery (usually CR2032 battery) on your motherboard with a fresh battery of same type and then start your machine.
