    Power problem on Presario CQ61-400ES

    Hello all, i`m reading this wonderful forum for a while now to know that this is the place i` gonna be helped.
    Shortly, i do computer repairs, but when it comes to MB repairs, it`s not my primary competence.
    I got a Presario CQ61-400ES Intel motherboard, integrated video, with a power problem. The battery is dead, when i plug the adapter the white led lights for a few seconds and turns off. The battery led does not flash (with battery attached). But if i leave it like this 2-3 minutes, the led of the battery starts to flash (i suppose to tell me that it is a battery that needs to be replaced). At this point if i press the power button the battery led stops flashing for a few seconds and after that starts again. Apart from this, nothing else happens. No power on, no leds, no fans spinning, no nothing. Completely dead. Without battery, no power, no nothing. Only the led on the DC jack lights for a few seconds.
    The customer didn`t bring me the original HP adapter, but one that does not have Voltage on the middle pin (Dell i suppose). Think that this is not the problem though. I`ve disassembled the MB and red the previous posts. No CQ48 on mine

    Where to now? Any help will be highly appreciated.

    if you dont have an original hp adapter, and if there is no voltage on the middle pin, connect a 180k resistor between +19v and middle pin, it should work. Like dells this model wont work without middle pin.

      Thank you for your answer. However, i`m not sure that this is the problem here, because it was working with the same adapter right before it stopped working at all. Tried the adapter on another HP notebook, working with no problems. Only not charging the battery.

        bad bios is very common on this range, try reflashing with external programmer or replace bios chip

                You need to buy a programmer from ebay and then download the bios file and flash it. Or just bring it to a repair shop.

                  Another HP Laptop may not require middle pin. What i know is CQ series wont work without middle pin.

                    Thank you all friends. BAD BIOS is the winner Re-programmed it and now everything is fine. Works perfect, no battery charge though for missing the middle pin voltage. Thank you all, problem solved!

                        Acer Aspire 5 A514-55 - won't power on, no charger LED, battery not flat - usual suspects?
                        by DenK
                        Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.
                        1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down

                        Acer Predator Helios 300 - will not power up if battery is CONNECTED
                        by survivalbloke
                        This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

                        by sam_sam_sam
                        I have had this battery backup for at 2 to 4 years now and the battery when bad and this is weird battery size it is the same length as a 12 volt @ 7 amp hour battery however the depth of is not the same as a 12 volt @ 5.5 amp hour battery

                        I have several battery packs that are A123 batteries cell so I bought a lipo4 BMS balancing protection board for these batteries and I have a configuration that is 4S 3P these battery packs were 3S 2P so I reconfigured them but left the tabbing on one side of the battery row of battery cells and re-tabbed the other side to the configuration that...

                        HP Pavilion Power 15-cb G75A can't work on battery
                        by sopik78
                        Hello,
                        I have an interesting issue with an HP Pavilion Power 15-cb011nc laptop. The laptop works perfectly fine with the AC adapter connected, charges the battery correctly to 100%, but when the power adapter is disconnected in Windows, it shuts down immediately. When trying to power it on using only the battery, it only shows the "HP" logo, and as soon as it starts booting the operating system, it shuts down immediately. However, the voltage on +VIN is stable and holds at approximately 17V, which means the MOSFET controlling the battery power is correctly open and supplying the...

                        Asus Probook P5440UF-XB74 power issue
                        by GLISIT
                        Hi all,

                        TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                        I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                        A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...
