HP EliteBook 840 G5: Iscrizione allo store con partita iva?

Thu, 08 Sep 2022 01:16:13 -0700

Qualcuno di voi è iscritto allo store come azienda/partita iva?

Ho la necessità di inserire in anagrafica fornitori iFixit , ma per procedura interna deve essere rimepito un form, altrimenti non posso creare ordini di acquisto nel mio sistema di gestione.

Sapete se accettano solo pagamenti diretti con CC o se possono essere definiti metodi di pagamento come rimessa diretta in fattura?

HP EliteBook Folio 9480m: Pressing power button turns on keyboard light but nothing else happens

Sun, 19 Jan 2025 21:12:52 -0700

When I press the power button, the keyboard lights will enter some kind of loop, where they turn on and off repeatedly, but nothing else happens, no image on screen, no boot messages or image, nothing.

I tried replacing the battery with a new one, and tried using a different charger, and still have the same issue.

A late update: ~1 month after resolving the issue, the laptop started having similar problems again. To solve them, i just removed 1 of the RAM modules. Haven't had any more issues, apart from a defective battery. So it seems the problem was the RAM.

HP EliteBook 840 G6: Laptop power blinks white and orange, not turning on.

Fri, 25 Jul 2025 23:32:44 -0700

I have a new laptop, worked fine and then it was dropped. And now it no longer turns on. The power button would light up along with the caps lock light then turn off. I plugged in the charger and it shows no life. So i took the battery out and put the power adapter in and now the indicator light blinks white, amber, and then stays amber. Sometimes the keyboard lights will come on and sometimes it will not but the screen will never come on. Might I mention that while putting the battery connector back in, a light on the board would flash white and go away. Same with the power adapter. I'm not sure what to make of it, I contacted HP Support and they were no help.

HP EliteBook 840 G2: Battery changed with new one still not charging.

Wed, 27 Jul 2022 15:46:16 -0700

The battery is isn’t charging after placing a new battery in, it seems when the laptop is started it shows as charging then stops.

I have downloaded the HP assistant and done a battery check, the results come back as no battery detected?

I am not sure what the issue is, but we have also notice the date and time is out of sync and the laptop is only running on the AC charger, could this be an issue with the mother board?

HP EliteBook 8440p: How do your remove the keyboard?

Mon, 19 Mar 2018 01:30:10 -0700

HP's video take apart instructions say nothing about how to remove the keyboard. It just shows it already out. I snapped off one esc key tring to pull it up and stopped there. HP was no help. I've removed a ton of keyboards from Macs and there are sliders at the top of them, and I assumed, most laptops. On the HP I slid the 4 locking sliders back but couldn't lift or pry the keyboard off. So, what's the secret?

HP EliteBook 840 G6: Charging LED blinking orange (500ms freq)

Mon, 23 Feb 2026 15:06:47 -0700

My 840 G6 doesn't turn on anymore, regardless if I plug in the original charger or a 100W USB-C PSU.

The only sign of life is a blinking orange LED beneath the charging port.

I tested original charger with multimeter, so that is fine. Also I checked the USB-C PSU. When I plugin a volt/ampere meter to the USB-C charger I can see the PD communication from laptop to PSU is fine: it get's up to 20V and pulls 0.4A.

I also tried to detach battery and CMOS battery, press power button for 15-30 sec then only attach power supply. Unfortunately that didn't help.

Does one have an idea what that blinking orange charger LED means? Only thing I can find online is according battery things. But that LED also blinks if if detached the battery and only provide power supply.

Are there good points to test voltage on the motherboard? Does the battery voltage pins need to have ~11V if PSU is attached?

Update - 2024-03-10:

For my feelings it's pulling to much current: 420mA with not battery attached. Feels like there is somewhere a short.

I did different measurements, but don't know how to narrow it down from here. Can someone guide me on measurements?

Update - 2024-03-14

Seems like the thunderbolt controller (or some peripheral of that) causes an issue. I tested with my fingers which chip is getting really really hot and it's that JHL7340.

Can one say if it must be that chip causing issues if it's getting hot, or if that might be related to some of its peripheral? I'm wondering if it's really shorted, as PD exchange with USB-C PSU is still working (but maybe it's not that chip doing PD exchange?!)

Update - 2024-04-29

I did a lot of reading and repair video viewing (thanks Sorin) now and decided to order a replacement chip on aliexpress as well as a cheap hot air station on amazon. After some trials on an old broken PC motherboard, I replaced that BGA chip in a fearlessly mood with the new one, with the result of "no short anymore".

Unfortunately that doesn't seem to be the only thing... Measurements on the main power rail look like the second mosfet is also shorted (0 Ohms resistance). So first mosfet gets 20V input, on the output it's gone...

So now, as I have the tools, I ordered that one on aliexpress too and will try to replace it. Will keep you updated, just in case someone stumbles over that topic here.
