Re: Will not power up
FirewallAvat: Your problem is likely because your battery is dead and the adapter isn't charging it. This may be due to broken connections in the cable from the adapter. Flexing often causes the wire inside to break near the plug. Generic replacement adapters are available, or the wire can be cut back a bit and a suitable replacement soldered on. The cause might also be broken solder connections on the main board at the power jack, This is common from stress due to the power plug flexing. It is usually possible to open the computer and resolder these connections, although sometimes there's too much damage from arcing before the connection fails entirely.
DocBrown: Does the power LED on your computer come on when you connect the adapter? If not, try the adapter in another outlet anyway. Sometimes one outlet in a strip can go bad. Check the output of the adapter with a voltmeter. If it's bad, replace it or try repairing it as noted above. If the adapter is good but the light isn't on, you might have the bad power jack as well.

You may try this fix. No guaranties though. Remove the battery and unplug power cable. Then hold down the "power" button for about 10 seconds. After that plug it back in and try turning it on. Again, this may NOT work but it has for others.
hi i wonder if the mainboard has suffered a power failure due to power shortage through electrical system that it was connected to . if the lights do not appear on the media strip below the video panel and above the keyboard, that would indicate a power failure has resulted from the power supply burn out. That being said the mainboard has suffered a electrical sudden power down. Have you tried the AC adapter to ensure it works ? I would need the entire model number and S/N of the notebook to get some feedback from HP
Due to the heavy processing
the PC heats up. Excessive heatup beyond usual is alarming and PC shuts down by itself when the processor/ CPU temperature exceeds the safe temperature limit. There are mainly two reasons for heatup. Heating issue generally occurs due to fan
failure, which may damage the system, if not checked and resolved properly. Another
most likely cause of overheating is the dust present inside the PC, which clogs
the fan and heatsink. As you have mentioned that the fan is not running, most probably the fan has gone dead or it may have stopped working due to clogging with dust and hence it needs cleaning or replacement. To do so, you need to purchase a new fan and disassemble the laptop to replace the fan. To
replace the fan, you have to disassemble the laptop and for that you
need to have the laptop repair manual that can be downloaded here. (I think that you have HP CQ60-419WM Laptop). The
repair manual contains all the information as well as graphic
illustration about disassembling and replacing the fan. Please refer to
Page 4-41 for complete details.
you are able to work inside such electronics and have some
disassembling experience, you may try to do it yourself. However, if you
have no experience, it is strongly recommended that you seek
professional help from HP authorized repair/ service professional.
Hope it helps! Good Luck! Thanks for using Fixya! CreativeTECH
check the underneath of the laptop, there should be several access panels, remove these and look for fans, clear them of any dust you can see, the main fan should be blowing through a heatsink (lots of small fins) try to get to the part between the fan and heatsink as sometimes you can get a lot of dust build up there.
Here's what you can try.
1. Remove the battery and try turning the laptop just from AC adapter. Maybe the battery is bad and shorting the system.
2. Try turning it on just on battery power (with AC adapter removed). Maybe the AC adapter is bad and shorting the system.
3. Try removing memory modules one by one. Maybe your failure somehow
related to memory. Test the laptop with only one memory module
installed. Try either one.
If nothing helps, the laptop still turns on and off by itself, most likely this is motherboard related failure.
Remove your cpu/gpu heatsink, apply a ermal bonding, this will prevent shut off because of cpu/gpu overheating(chipset detects temperature faulty in the firsts seconds of operating your laptop), if this didnt resolve your problem, naybe and issue with your Mobo.
You probably put more than a pin-head size drop of heat grease compound on CPU, thus "bleeding" over on the CPU, effectively overheating processor (very common). In any event, your problem is overheating -that's *the* place to look for now.
Please try to remove the battery and than try to switch on the laptop directly from mains power and if it works than its your battery problem or if it still not starts than there is possibility of some components of your laptop may fired due power fluctuation. So go and contact service station.
