ThinkPad X61s Type 7666-AH2 will not power from battery

Hey Gang:
With original as well as brand new replacement battery when AC adaptor is plugged in battery (green) indicator shows fully charged battery and OS will boot no problem. When adaptor is unplugged battery  indicator turns off and machine will not boot.
My suspicion is a bad system board (unfortunately customer did not supply diagnostic discs)
Your thoughts would be appreciated!
Thanks

I don't trust replacement batteries. Too often they get delivered in a poor quality and need to be replaced twice until getting a working battery, even the power manager shows a good condition.
Try to meet somebody with the same notebook and exchange batteries for a test with him.

  • T60 will not power up (battery status led green, power status led green)

    Ok so I have been researching this for a couple days now. Trying various things............
    Including the famous 10 second power button press discharge.........
    Symptoms:
    1st Disclaimer - coffee was exploded all over the laptop but has been running for a month.
    Symptoms:
    It has been working post coffee spill (several weeks ago) as long as you left it running. I get cocky and turn it off then it wont come back on.
    The laptop has exhibited the inability to power on since but I have been able to get it  to turn on several times since.
    green power light comes on with AC adapter only
    plug battery in and the battery light goes green
    press the power button - both lights go out
    I replaced the keyboard, battery, tested for 20 Volts on the AC adapter, tested for 2-3 volts on the CMOS battery.
    I tried testing for 20 volts on the motherboard where the power supply cable connects. I have most of the laptop broke down still.
    I did get it running again last night as a result of me incorrectly using the multimeter and short circuiting the power supply connector .
    It booted up and ran fine and I even tried turning it off and on again several times.
    I thought it might be a heat issue. I turned it off and tried to turn it on this morning and it will not power up.
    Same symptoms as before.
    no battery, only power connected, green light comes on, plug in the battery, battery light goes green, try to turn it on and the lights go out.
    It seems like it is fixable but I am not sure what to look for next.
    Or should I be looking for another system board...........if so what should I replace it with
    This is an IBM T60 Type 2613 15" screen.
    Solved!
    Go to Solution.

    Welcome to the forum!
    Your best bet would indeed be a new system board. Any single one from a non-widescreen T60/p will work.
    I've got dozens of them available - send me a PM if you're interested.
    Good luck.

  • T60p will not power up

    my t60p 8744j2u will not power on. battery light flashes when ac plugged in. is my motherboard toast? if so I'd like to upgrade to the best configuration to run autocad. any suggestions on a new motherboard? Graphics card? CPU? When it was running the fan made the loudest noise. Could that have caused overheating to kill it?

    Huh...T61 with nVidia graphics...I'm fairly certain that you'll need a new motherboard or a replacement laptop altogether.

  • Thinkpad will not power up

    Hi,
    I have a Thinkpad A31 2652-C4U
    The unit will not power up.  The light that indicates the unit is receiving charge doesn't even come on, and hasn't ever since I came into possesion of the unit.  
    I know the power supply works, I tested it with a volt meter, and besides, it's also randomly compatible with an old Compaq Presario I have lying around, and it powers that unit up quite well.  I've also checked the power input on the unit itself, and it's not loose.  Doesn't matter if I leave the battery in the unit or take it out either
    Since I received the unit for free, I'm willing to invest a small amount of money into it, just to see if I can fix it.  But none of my typical diagnostics are applocable here, because the unit doesn't power up.  So I was wondering if there were any suggestions as to what I might try next.  
    Oh.  The unit has no hard drive either.  The hard drive caddy is gone too.  The unit does have a stick of ram, but I don't have any other computers lying around that are compatible, so I can't test it.  Either way, those issues should effect the lack of power getting to the unit.
    Anyway, any help you guys can offer me is greatly appreciated.  I'd like to see what I can do with this thing.
    Thanks. 

    OK...let's try this:
    A30 board could be fitted into an A31 shell with some playing around, but these support only P3M CPUs while A31 are equipped with P4M CPUs. RAM is PC133 vs. DDR 266 on A31/p.
    Everything else...keyboards, LCDs, batteries are interchangeable.
    The board itself must be from an A31 and not A30/p or A31p if you're looking to get the machine running the way it's supposed to be...
    Everything you need to know in the respect of part numbers, removal procedures etc. can be found in the HMM:
    http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-39796
    Hope this helps and feel free to ask for clarification if needed.
    Good luck.

  • Need Help HP DM3 (DM3-1130us) Laptop will not power on. No power at all except for light on a/c jack

    Hello, I need some help.
    I have a HP DM3-1130us Laptop that will not power on at all.
    the only thing that happens when I plug it in is the power jack lights up.
    When the power button is used absolutely nothing happens.
    No power, no fans, no leds, no on/off cycles, no beebs, absolutely nothing
    just the light by the power jack that says the cord is plugged in.
    The laptop has Windows 7, 320gb hdd, 4gb ram.
    I have tried new power adapter and still nothing.
    I have taken the battery out and tried and nothing.
    I've tried the option where you take the battery out and hold the power and nothing.
    I have tried with different hard drive and no hard drive and nothing.
    I have tried reseating the ram and tried new ram modules still nothing.
    So I am kind of stumped on what to do, the laptop will just not turn on.
    Its not under warranty anymore so cant send it off.
    It has not been exposed to any elements(extreme heat or water).
    and its never been dropped or anthing.
    Im kind of wondering maybe the power button board its self is bad?
    If feels fine, its not loose or anything but could it
    have just stopped working? for those who are not familiar with this model.
    the power button is on the side and is a kind of drag and release button.
    Its also on the same board with the Wifi button and 2 Usb ports.
    But Im wondering before I buy a new one if this is what it could be.
    Or could the motherboard its self be bad?
    But even if the motherboard is bad would it still power up
    just not post?
    Also does anyone know of any other way to try to power this laptop up
    without using the slide button. I mean kind of like off a Dv6000 you can power the laptop on by using the Quicklaunch buttons on top but this laptop does not have those.
    If anyone can provide any information I would appreciate it.
    Thank you.

    Hey Tyler,
    Unfortunately it is difficult to troubleshoot this type of issue. The majority of the time when the computer wont power on with the same symptoms you described, the power supply board is faulty. Most of the time if the motherboard is bad it should at least turn on or so some signs of life. Like I said, this is most of the time. Sometimes it could do exactly what your experiencing. I would suspect the power supply board has failed since you are not receiving any sort of lights, sounds, etc.
    You could check the motherboard for swollen capacitors or loose solder joints but sometimes you wont be able to find anything.
    I hope this helps answers your questions,
    Sean

  • My brand new iMac will not power up after an update restart, any suggestions?

    Any suggestions on why my IMac will not power up after it done a restart?

    Try an SMC reset and PRAM reset: https://discussions.apple.com/docs/DOC-3603
    If that doesn't help:
    See if it will start in Safe Boot: restart holding down the Shift key until you see a grey progress bar, type your admin password when prompted, let it continue to (hopefully) boot. Restart as normal from the Apple menu.
    If that didn't help, try booting into the Recovery HD: restart holding down Command+r and choose Disk Utility from the four choices when they appear on screen. Once DU has launched select your Macintosh HD on the left and click on 'repair disk'. If anything gets changed click on repair disk again until you get a clear pass, restart as normal from the Apple menu.
    If you still have problems, give AppleCare a call.

  • T60 suddenly switches off, will not power on again, DVD drive related?

    I have searched and searched for this, and although finding many "T60 will not power up" I haven't 
    found any with this twist.
    My T60 is ~2 years old, and the problem just started recently. Working on battery one day, the laptop 
    suddenly died - like instant loss of power. I could not turn it on again. One strange thing though: 
    When I removed the battery and re-inserted it, the batt-icon-light came on briefly (a blink). If I then pushed the power button it lit up for 1 sec and then went out, not booting. Repeating it, without removing the battery, it didn't light up.Ok, thinking maybe the power supply was dead, I took it completely apart, removing also the harddrive and the DVD drive. By chance I then saw that it had "fixed itself". I resembled it and it worked again, powering up like nothing had happend.
    Then it happened again yesterday. I read in here about the "push power 10 times, hold power down 30 sec" etc, but had no luck with that. Again, when I inserted the adapter cable the light came on (power plug + batt light) but when pushing the power button they went off, and if I removed and reinserted the plug same thing again.
    I then read about removing HDD and DVD drive, and that did it! So, it happened again today and this time I just removed the DVD - and it booted again. 
    So, after this loong description here I hope that some of you have tried/seen this before or have an idea what it can be. I left the DVD drive out, and it has not happened again...yet (it's been 5 hours only). 
    Ideas?
    Thanks in advance!
    Martin.

    Hi Nordal,
    I know this is an old thread, but since I too am now experiencing inability to startup by T60 and seems to be getting worse in the last months, I was wondering what additional things you may have learned in the last 2 years since facing this issue.  My system will typically be in standby or hibernate and when I open lid to start it up again, Power and Bat light go out and cannot start it.  No beep codes, nothing.  Previously, recovery was to pull battery (which is now new Lenovo as of last month and working great), hit power button a few times and then hold it in, put battery back in and AC adapter, then it would start up.  In last few days, this no longer works.  I have to go through similar step, but now I have to startup only with battery, once in Desktop, I can plug in adapter and no issue until next time.  I have three 90W AC adapter all putting out correct 19.5-20 VDC.  Have rulled out an adapter issue, I believe.  Concerned about something on motherboard being flaky, but cannot pinpoint issue.  A few days ago when this happened, I had to pull CMOS battery, wait a few min., then put everything back together and was able to boot.
    Have never pulled anything more than RAM, CMOS battery, main battery, and AC adapter.  May have to try DVD drive next time.
    Thanks,
    Kaz
    It's probably best to start a new thread instead of reopening one thats 2-3years old, but from what your describing it sounds like your slowly ruling out everything except the system board, nothing you don't know already.
    I don't normally deal with T60's, my main focus is T61, but I do have a source for the boards if you were to need one, as well as having a source to get the older boards reflowed. Some of the older models had problems with solder connections cracking when the board would flex, which can be repaired on an infrared reballing machine. My friend Dominic (realblackstuff from thinkpadforums.com) operates a website where boards are collected and sent off to be reflowed in wholesale lots. It's quite reasonably priced, as are the T60 boards pulled form grade "A" corporate laptops, but lets hope you can find a lesser component that is causing the problems.

  • HP 60 will not power on ?

    I dropped my HP 60 and broke my screen and I think a something else because when I power on my laptop the power light blinks  continuously(this is while on the ac adapter) the laptop will not turn on without the adapter.... I took apart my laptop and did not see any broken piece. Aside from the screen which Im waiting to replace because I want to know if I have a more serious/expensive fix that is not worth the aggravation. I noticed that the bottom of the laptop where the fan is located gets very hot after a few minutes, but I hear the fan spinning? Or is the fan not actually spinning? I left the laptop on the charging adapter to see if I could get some juice into the battery and operate the laptop without the charger, but no luck.
    I beleive it could be a battery and or fan issue, plus the screen... please help!

    Solder type  power jack  replaced
    Check for cold solder joints. Solder joints should be bright,not dull colored.
    Did you try a hard reset before you started opening the laptop? 
    Always try to reset firmware (BIOS) before beginning any disassembly for a no-start condition.
    Remove the battery and unplug the DC power adapter.

  • My Powerbook will not power up, but I can hear the fan running...

    Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

    Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
    This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
    Any answers to this yet? I think I'll call on this and report any success to this discussion.

  • My ipod will not charge from a wall socket but will charge using the same cable if the usb end is plugged into a computer or an airport power source. My iphone and ipad charge fine on the same cable usin ghte same wall plug in the same wall socket?

    My ipod will not charge from a wall socket but will charge using the same cable if the usb end is plugged into a computer or directly into an airport power source. My iphone and ipad charge fine on the same cable using the same wall plug in the same wall socket. This makes no sense but I see that it has been posted as a problem elsewhere. This must be due to some kind of degredation of the Ipod. . It is not fixed by IOS resets as others have noted.
    Has anyone asked Apple directly about this?

    Hi there Apples or Pears,

  • My iPhone 5s will not power on and I need my serial number for support.

    I am attempting to get help through Apple Support- Chat, but I need my serial number.  It is not showing up in iTunes under the device preferences.  Any other ways to retrieve the serial number through iCloud?
    If anyone has any idea of what is going on with my phone, I would love some assistance.  I live 45 minutes from the nearest Apple Store.  Here's the situation:
    About 2 weeks ago, my phone started shutting itself off and restarting randomly.
    About a week and a half ago, I would randomly get a blue screen and then the phone would restart multiple times.
    About a week ago I turned off Touch ID in an effort to resolve the issue, after reading some fixes from this community.  That seemed to help.  I do have the animation turned off, so I had read that there may be an issue between the Touch ID and animation reduction.  If that had not helped, I was going to turn the animation back on.
    Last night my phone seemed fine.  I did hear it restart in the middle of the night once, but this morning it will not power on at all.
    I tried connecting it to my computer through iTunes, but iTunes does not see it and I cannot access the device information from it.
    My phone is less than a month old, and for the first two weeks it worked great.  I am taking it into the AT&T Store today where it was purchased, but I don't really have high hopes for a resolution.
    Any help is much appreciated!

    Sorry AT&T store won't be much help.
    I suggest you make an appointment with the Genius bar and then go to the Apple store.

  • Macbook Pro will not power on without battery installed

    Hi there,
    I have a Macbook Pro A1226 that fails to power on without a battery installed.
    i.e. will not run off AC power on its own. I have tried 2 other power adapters, no change. All 3 adapters are outputting the correct voltage without fluctuations.
    But, if I am in OSX with a battery plugged in, shutdown the laptop, remove the battery while AC is still plugged in, it will power back on without any issues. But as soon as I remove the battery, it will not power back on using just AC.
    Is this an I/O board issue, or a mainboard?
    I have power drained the unit and reset the parameter ram.
    Thanks

    Any update on this? This is the same thing that's going on with my laptop right now. I was at the Genius Bar and they said they can send it in for repair. Takes 7-9 days and costs a minimum of $310. At the time I was there, my computer wouldn't start up at all, because the battery had drained to less than 20%. It didn't even start with just the power cord (no battery in). The "genius" finally got it to work by doing a PRAM and SMC reset. Got home and was able to recharge my battery to 100%. Used my computer for 2 days before I dared to take it off the power supply. Lo and behold, as soon as I take it off the power cord, then re-connect it, it shows "Not Charging". I tried to do SMC again, but no luck. Keeps saying "not charging". Even tried with a brand new battery. Do I have to get the I/O board thingy replaced?
