Laptop Totally Dead

[JohnP8]

Hi All, I hope someone can help. I have an HP Envy Notebook i7 with 12Gb RAM. The laptop is just 24 months old & about a week ago it flashed a brief message about 'Thermal Shutdown' & switched off. It is totally dead. No LED's show on Laptop even when charger is plugged in. I have measured the charger voltage & this is good (19.5V) - I tried a 'HArd Reset' by removing battery for 30 mins & still no life? Has any one got any ideas or does this sound terminal. I've obviously very upset as this was a £1,000 laptop & is only 2 years old... 😞

Many thanks,  John.

Could we maybe have the model number? But I have to say you have done about everything anyone would advise doing for diagnosis and it looks like a dead motherboard.

Sorry - yes model number is 15-ae109na. Really appreciate your help. John

OK - the thing that confuses me is that not even the charging LED comes on when charger is plugged in - does anyone here on the forum know what's required to make this light - obvously PC etc. is not turned on at this stage so I assume CPU etc. is not required. It shut down initially with the 'Thermal Shutdown' error so CPU must have been involved so even if CPU is dead why wont charging light come on????

Thks,  John

I did not say the CPU is dead; the motherboard is dead. Depending on where the failure point is located dead can mean really truly dead. No electrical response whatsoever. Also it is not impossible just the adapter has died and the battery ran down to nothing but given your warning message right before it shut off I do not find that likely. I think it is really truly completely dead.

Once again thks for your quick reply. I have measured voltage out of charger & it was reading 19.5VDC - I also had opportunity to try a different charger & this also gave no response. Up until the failure the laptop worked faultlessly for 2 years then all I got was a single 'Thermal shutdown' message with no warning & now dead. I guess its possible that if it did overheat excessively it has 'fried' something on motherboard that is related to charging? I'll try & get my hands on a relacement battery & give that a try. Thank you again for your support.  John

Don't spend money on a replacement battery. First try removing the battery and running it only on AC power. The battery can fail internally and prevent power on but I have never seen it completely block any electrical response. I think it was a catastrophic meltdown unfortunately.

Hi Thanks. Yes already tried that & no joy - still nothing active with battery in or out (no charging lights or anything). I've dropped it off at a PC repair shop so hopefully they may be able to shed some light on problem.. fingers crossed - John

I have two basic HP laptops and both are dead.  Tried removing the batteries and holding down the power button etc. and they don't charge at all. They haven't been used that much.  Just about 4 years old. Model number is 15-af113cl if anyone knows if they can be revived or if it's worth the money to.  They have a couple years of high school left and should have lasted the duration.

It is so rarely cost effective to fix a laptop that has completely died its almost not worth discussing. If you can do the labor yourself to replace a motherboard and have the ability to source a replacement in a guerilla manner so as to incur the smallest possible cost, maybe it makes sense. I mean something like buying a parts unit on ebay that has a smashed screen or something like that to use as a parts donor.
