Laptop HP ProBook 640 G8 with Charger

[TechUser00]

The only way to stop a BIOS update is to pull the power off. No normal shutdown is possible under BIOS update.
Kindly refrain from Blame Game.
@ShivamRaj I understand your concern. But you should also try to understand @manohar5321 prospective also. He wanted to use the device that why he bought it. Not to play and break.
BIOS update is a speculation only. Even if it happened try to help him out. If you would have been the buyer you would wanted the same right. A perfectly working device.

Whoever has the laptop, if both buyer and seller mutually agree you can try disassembling until you can reach CMOS battery. Disconnect or remove the CMOS battery as well as the laptop battery. Press and hold the power button a few times. Leave it as is for an hour or more.

Try powering on with minimal hardware. Just one stick of known good RAM should be enough. No need for even storage. First time you boot after this, if you any lights or fan spin, just wait for 5 mins. It might start working.

In Dell and HP laptops, I've sometimes gotten the LED/Beep codes corresponding to BIOS issue when it refused to POST. Clearing CMOS has often fixed it.

Based on available information here, I think seller should honor the warranty period given to the buyer.
As reported, the buyer simply did basic tests and turned off the laptop.
There is no mention of windows and bios update - such critical updates won't be initiated silently.
Even if the update did break bios it is sellers responsibility to help buyer and even accept return if unable to fix product - sure buyer is also required to use product as intended.

Seller also yet to confirm status of replaced battery and charger being genuine brand or they are 3rd party ones.

I am not saying the seller is at fault entirely, electronic products can fail and the timing could just be wrong! One my friend sold his 3070 gpu to other friend, worked fine for years with him.
Next buyer used one and the next time he tried to turn on pc - no display, no troubleshooting helped and finally came to conclusion that the gpu was gone! Friend took responsibility and refunded money.

If you guys can resurrect it then great, otherwise I expect seller to take responsibility.

Bios update applies upon boot/reboot. So if @manohar5321 shutdown his laptop. The laptop will not apply the downloaded BIOS update, it might apply normal updates partially which also shows message before shutting down, but certainly not a BIOS update, because it’s expected from the user that user is going away.

Now upon booting it will apply the BIOS update, because it’s expected that user will be present, also a message will be shown at boot screen that bios is updating.

As @TechnologyHell said if buyer/seller can take his and other members help to recover bios than let do that and after normal boot let check laptop carefully and if all ok let buyer enjoy laptop.

One solution right now is to externally program the bios chip.
I've done this for a desktop mobo, and it worked like a charm.
You just need an external bios programmer kit, download bios file, flash it on the chip externally.

Here the challenge would be downloading the bios flash file for the laptop, cuz unlike desktop boards, laptop makers don't offer to manually download the bios file.

We can only get to know that with windows logs maybe the event viewer and update history. If the disk is not encrypted it might be possible to boot into Windows from an another machine

As @drxart said, it should be fairly easy to extract the SSD, chuck it into a working system and boot from it. Windows Event Viewer will give you a clear understanding of whether the last system shutdown was graceful or forced. Further, by examining the "Application" log within the Event Viewer, you can even identify application events, including when they were started or stopped, and potentially pinpoint the last application executed (which, if we were to believe the BIOS update failure incident is true, would be the BIOS update utility exe).

Can you please try this @ShivamRaj

To be honest I would not have bought a laptop with physical damage. Probooks have reasonably robust chassis and a crack like this means that it has suffered a decent impact at some point in it's life , and is no longer rigid enough to protect the motherboard from flex which will cause hardware damage ( micro fractures in pc traces which cause intermittent failures) I have a work laptop in this shape which will crash or fail to boot randomly if you hold it in one hand.

Bro don't shock me early in the morning.
I was like when did I sell this laptop, and would have to refund for it

Hey its me remember u owe me a laptop macbook m2 remember ? If not mods ban this guy..

On a side note from reading the whole thread , it all seems assumption from The Seller this happened that happened maybe he updated his bio etc , Firstly I don't think machines automatically update bio anymore they show in their vendor menu like for me it shows in lg menu or for hp in their own app and then they ask for it and even if it does I find it hard to believe that seller never updated bio when he says he's been using it for a while and as soon as @manohar5321 got it suddenly hp releases a new bio which manohar never saw an intimation of and it started updating ..

Besides this was like maybe 10 years ago bhos update causes issues not anymore , most vendors have recovery button on laptop and recovery image on website, it's upto seller to make it work or refund imo also have known @manohar5321 for long time and done loads of deals on and off TE never had an issue is a gem of a guy .

Fwiw , 30 day testing warranty means just that , also if bios update could cause such critical issues half the people here let alone non techies novoices wouldn't be getting windows .

Seems simple case of corrupted / broken laptop which was fixed buy buyer and then he tried to pawn it off, it probably was working when he sent it but it was on its last legs due to physical damage etc or maybe the parts moved in shipping, but then he wudnt have been blaming bios or random theoretical issues that might have happened and just refunded .

Also tbh my policy in TE always has been if buyer ever complaints I just refund or take a return regardless that's the values TE is based on and seller should honor his commitment specifically after mentioning ' 30 day testing warranty ' which someone would only mention if there's a chance of failure . I am not saying he did it on purpose but clearly laptop was broken and repaired and probably on its last legs ..

In fact I sold lenovo gaming laptop when I joined TE in perfect condition i remember but after a month although no fault of my own screen had coloring issues he texted me and i paid for it even though I didn't need to..

I remember when I joined TE sold a lenovo legion and it has some screen colloring issue after a month's use and when buyer complained to me i still offered to refund or pay for the issue which I did even though I didn't need to, onus should be on @ShivamRaj to either get it fixed and refund it whichever way to works .

Besides of it's a bios or ssd issue a techies can sort it in minutes a , if incorrect shutdown caused issues half laptops would be dead.. and frankly all this fans running at full tc has no correlation to bios .

I hope you guys solve it amicably if not my opinion its upto seller to either get it fixed or refund else the whole 30 day warranty Shazam makes no sense, I know people on te who even refund even if there's on issue with a device for example let alone one with dents and stuff.

Agreed, i feel it's the same issue here either was already damaged but working sitting ona table , moved in transportation / courier and went back to its orginal state it wa sin when damaged..
Ugh seems some issues with my phone keyboard nvm..

 

[ShivamRaj]

Guys I had been using this laptop for more than 2years with no issues.

If you believe @manohar5321 had shutdown the system properly, it will never give this kind of issue/ error code. Please accept the fact that it happened while with you.

Please search google "HP 7 capslock blink", its not something system will create by itself. Happens only and only when it was in updating state and the stopped abruptly.

@pra300 that is what im using for past 2years and with no issues what so ever and the only thing that is replaced and added is New Battery, SSD and 4GB ram stick. If it was completely dead when received i would have not thought twice but it worked fine and next is the error code its giving which is something related to bios update stopped abruptly.

@kewlboy9 if it was in bios updating state where can we get the details. Will the details be saved in SSD.

@greenhorn if that was the case it will not even give this kind of error and one or the other parts would have failed with error in windows but that is not in this case.

I know you may all be techgeeks but the error code also needs to considered. Took the laptop assuming that the buyer didn't properly check but upon receiving and googling throughly through the web only then i came to conclusion.

I came to Hyderabad on office work. Once im in bangalore then only i can show to my known technician and get it repaired expenses are needed to be paid by buyer.

Or else you take back the laptop and show to your trusted technician get it fixed.

 

[Pyception]

No one is buying your imaginary bios update failure story

 

[ShivamRaj]

@Pyception its not imaginary dude its the fact, google yourself.

What if the buyer is not telling the actual fact and if at all there was hardware fault it wouldn't start in first place. One or the other error it would give on startup.

 

[Tobikage]

Now a days bios updates are sent through windows update and there is no way to stop it for security reasons.

+1

*But was an optional update that I installed voluntarily.
Installed on a 5300U Ideapad
Showed up as "Lenovo.Ltd Firmware 1.2.xxxx"

There was a clear warning stating not to turn off the laptop with the fans going a 100% during installation.

That changed some settings in the BIOS without any warning and asked me for a Bitlocker key on startup.
Had that saved fortunately so could log in after entering the whole key or my wife would've killed me if the data was a goner

Have received BIOS updates for a 6th gen Dell Inspiron as well (the BIOS was never updated prior and years out of date) and those were not opted in manually but came through the default windows updates.

Bios recovery or hardware check takes minutes ( even checking ssd for it ) if you are in Hyderabad , you guys can together visit a technician shouldn't be hard but if he says it's not bios then obviously you'll have to refund, seems fair tbh and if it's bios then it should be miniscule expenditure and you can pay it anyway , sounds fair to me .
Just hope u guys sort it out amicably

Who are you ?
How and when did I owe you a MacBook??

Evidence please

Recently released at end of April 2025 so recieving it a month or two later isn't out of the norm.

Dude i didnt even mention truth, its fact and you can google.

Really sorry buddy. I was acting on good faith. @nick.knack91011 Please create a new thread with evidence and involved mod if required. Please don't derail this thread.

 

[manohar5321]

Am ready to cooperate with @ShivamRaj , we can go together and get it checked by a technician. But if the damage or issue is extensive I would expect a refund from him. There is absolutely no chance that an entire laptop can go dead just like that. I've used computers over 2 decades and I know how to care for them. There is a very high chance that this was repaired earlier and using 3rd party batteries and chargers will never guarantee stable performance. If the caps lock showing 7 blinks indicates an issue with the bios and the suggestion provided by hp on their website recommends a bios recovery either through the recovery software or usb recovery why hasn't it worked for this model. That means this could be an issue far beyond the bios. This is just a theory but a possibility.
In which case @ShivamRaj should do the rightful thing and refund me the amount.
