Hi mate.. i have a couple of HP9470m ELITE BOOKs... one is running fine however the other has a blank screen on startup , even with an external monitor connected...the Caps Lock and Scroll lock keys blink 5 times together before i hear the fan and see a blank screen .. (ps the WIFI and Volume mute buttons at top right stay illuminated after power on)... HP 5 fashing/beeps suggest a "general mother board issue"...
The weird thing is that as soon as you plug in the power adapter the note book AUTOMATICALLY powers up withouththe need to press the power button??
Any advise would be great ...
Thanks.
Before anything try a first aid fix on it, open the laptop and remove the motherboard brush out the dust with a soft brush, then apply low he's on it with either a heat gun or hair drier, allow to cool then replace. If this doesn't work follow he instructions below.
You will have to open the laptop, get access to the motherboard, check the power adapter section, there is supposed to be a chip that suspend the power distribution to the board when you plug in your adapter till you press the power button, check well on of the is bad, use exact one from another motherboard to replace it.
@@dreamsetservices2847 cheers i will give it a try...it was my ex girlfriends pc after a messy break up...i did replace the hard drive with a ssd drive out of my HP pavillion TPNC125 .. i did also disconnect the CMOS battery... whether the disconnection of the CMOS battery or the possibility there was a BIOS password on the original Hard Drive msy be causing the 5 flash/beep "general motherboard failure " will be tricky to diagnose ...The computer was working before i pulled the original Sata drive and disconnected the CMOS battery..I will test the voltage on the CMOS battery and try and reinstall BIOS from USB... the weird thing is the cooling fan seems to be spinning really fast..
thanks for your help
peace.
@@andrewverran3498 where you able to resolve the issue.i have exact same issue with my elite book 9470. Would really appreciate a reply.thanks
@@michaelitegbe3789 no ..gave up.. dont even bother imo number of startup blinks suggested a motherboard fault, ..spent too much time on it and bought another one.. now i have a spare parts computer..
@@andrewverran3498 Hi Mate, the most common issue with this model is either the bios firmware or dead mosfet. 5 blinking error is usually caused by faulty ram modules.
Sir my problem is that when i plugin charger lights is on but orange light is not green when laptop is turn on then ME state in recovery mode is showing on the screen and then off how i fix this problm plz help me
What was the problem with this motherboard after all? I have the exact same issue
Am in Enugu (nigeria), can I get ahold of your services here for this particular laptop (hp elite book 840 g1) or if you can refer me to one of your trusted partners in the city, I would highly appreciate it. ( The power button blinks once when I plug it to the AC and nothing else happens. I have removed the battery and drained the static voltage too but it's not helpful)
If you have drained the static voltage and its still the same issue I.e (light blinks once when you plug it to light) gently remove the main board, use a workstation to heat the processor chip, set your workstation to 200 degree celcious and heat for 5mins while moving the nozzle at intervals to spread the heat evenly, this will help re-ball the processor and resolder disjointed legs.
For now I don't of a good board level engineer in enugu
what settings should I use on my multimeter?
Use 20 volts
@@dreamsetservices2847 Nice one. because of your video, I think I just got my 840 g1 working again after over a year. I can boot it now, I followed your steps, got to the bit where you said you need to replace the CPU "thought oh no, I can't do, that" then switched around the Ram sticks and it booted :) Thanks so much
@@tom-xu1ek you are welcome, am so glade it helped, remember to like and subscribe
@@dreamsetservices2847 Done and done. Thanks and have a happy Christmas and new year
Have seen the video but getting the equipments needed to actually work on it(the laptop) myself or trying to find a good technician now is the problem..like, which one is cheaper and safer ?
Get a hot air workstation with heat measurements thermostat
I did everything but there is no change. What can I do?
Check the power I.C for consistency and Replace power accordingly
How much motherboard of hp elitebook 840 G3
Do you want fairly used or brand new?
How much are both
Mine shutdown sundenly after battery low message. Now it doesn't turn on and even if i plug in the power cable there is no charging light
Drain out the static charge by holding down power button for 60/seconds
@@dreamsetservices2847 still not working, also i have tried to plug in without battery but still no charging indicator as well buttons are not blinking. Idk wht else should I try?
When I plug in my charger to my 840 hp laptop. The power button and the caps turn on themselves automatically.
Remove the battery and the charger from the laptop then hold the power button for 30 to 40 seconds to drain the static charge, the plug the charger in and turn it on
Am having the same issue
😂😂😂😂😂
Apenas desmontou o laptop, não ensinou nada mais.
