If your battery will not charge, you need to run a test on some components on the laptop. The battery, the charger and the laptop itself. Once you detect the faulty conponent then you replace it with a new one.

To test the battery:
1.Power off the laptop,
2.Take out the battery,
3.Insert it in another laptop,
4.Check of it will charge,

If the battery holds a charge there, then it means the problem is not from the battery, but if it does not hold a charge, then it means the battery is defective and need to be replaced with a new one.

To test the charger:
1.Unplug the charger from the present laptop,
2.Connect it to another laptop to see if it will charge.

If it charges the laptop, then it means the charger is alright, and if it does not charge the laptop, then it means the charger is bad and need to be replaced.

To test the laptop:
1.Turn off the laptop,
2.Disconnect your present charger,
3.Remove your present battery pack,
4.Insert a well tested battery into the laptop,
5.Connect a well tested charger to the laptop.

If it powers on, then it and charges, then it means the laptop is working fine, but if it does not charge, then it means the connection port of the laptop is bad.Hope this information was helpful.

NO OS stated ,answering for windows.
well dim is complex on laptops
I bet it does not stay dim in BIOS screens
the F1 info screen, so...
but does only in windows running, right?

The PC autodims the screen for 2 reasons (by design)
a battery weak. or setup to run dim when on battery only mode, in windows power settings,
reason 2, the screen camera is used to see when the room is dark, if yes, it dims. this to is a a setting in power settings of windows.

click start, click control panel,click power icon.
click advanced, see "power" settings
you will discover many things are (on battery do X)
all laptops with windows, set it as you want.

Yes. I'm assuming your printer has the old style Winchester plug instead of a USB jack. It's called a USB to parallel adapter or a USB to printer adapter.

sorry so slow, the spammers here pushed you to way down the list.
I guess ************ means expletive, words,? IDK nor care. but..

W8.1 is clear , no PC stated, at all just HP, 1 of 10,000 models
for near 4 decades !
PCs have up to 7 levels of passwords, even more on enterprise grade or for sure all very new PCs.
even some so good its impossible to hack out.
Why not just post your bad screen, as a photo, use your cell phone camera and post the screen below, click add photos.
in real PC repair shop the technician sees it with his eyes
and posting here in the blind is super useless,
we can not guess what you see, nor when !!


if just the windows login password lost
say so..
as that sure can be hacked.
in fact google that for 1million hits.

AIO are junk sure.

there are 2 issues here,
1: do you have a MS account? yes /no?
2: if yes, ask them MS how to delete your account. it is easy.
google how to delete my MS account. (millions ask a day)
3: of no live.com MS account at all , that if you windows login looks like username xyz123
and not bob1234@live.com Or outlook.com or x360.com
then it is not a Microsoft account locked in password but is what we call local. account.
4: if local account there is 2 ways, I never do this but here is the answer,
a: in control panel, click users, and delete them all 1 by 1.
I bet the last one refuses (IDK ) last admin refuses, due to running now, like shooting your horse while riding him (texas humor)
b: boot the PC and hammer F11, this invokes the magic windows HP full recovery. (F11 run fresh w10 install)
do that and its like new.
one answer.
I answered all ways, due to my not knowing if you say wanted to keep the MS live account for PC #2 , on order.
good luck,
next time get a Dell OptiPlex 3040 or newer, way way better, PC.
with a future too.

AIO means too cheap to buy a real Desktop, that is what it is.
some AIO love to fail; many have bad PSU that can not be fixed.

  1. Turn on the power and press F11 to run recovery without starting Windows (on some models esc key and then F11 key.

IN never came with w10 from, HP ever.
ok, HP told you not to use W10 , HP does not support w10 on this PC, now you can but some things will be dead.
I can list them all but will not now.

musical OS day, ?wow !@
you installed W7 from whom and what, ? MS disks or HP?
you installed w10 from whom? not HP but was MS, so was a fresh install or upgrade install, I cant guess or see what you did, not ever.
why not just run w7 and not upgrade, so HP will give you full support , why not?

head set, so does that mean , 3.5mm phone jacks dead
or are those USB head sets. we cant guess that either.
USB phones will cause chaos if not set up manually, ask.
3.5mm is child's play,
I own many 8540w, laptops.
all run W10 but I had to get the drivers to all dead chip from the chip maker, HP does not have them, because they dont support w10 here, nor do the security software work at all ever, there.
and more, the speaker control panel buttons are dead too...
until i fixed that panel, with a HP w7 force fed driver.
this pc came with XP ,vista or w7 , 32 and 64bit.
so what did you load, 32 or 64 bit, i cant guess that either.

so let me guess,
3.5mm dead, but not internal speakers,
so load this HP driver, off your official HP page.
its shows audio there see that, sp12345.exe
match the BITS (32/64) hint hint
IDT High-Definition (HD) Audio Driver
sp46721.exe (27.8 MB)
this driver is certified on w7 only.
so if it dont work then we go the chip makers site
for a newer driver,

it must be a 4 way match.
OS same
bits same
chip same
and driver to match.
in all cases.

full support here, at HP
link is 64bit. back up one page to get 32'

1. This is a quite old motherboard. After years of usage the capacitors next to the processor might pop out and no longer work, therefore the processor does not get the required power. Check these capacitors. I added a photo of faulty capacitors. Check them. The top surface of them has to be flat without any electrolite(brown stuff) leaked out. This is a hard to fix issue because you need to solder them out and replace them with capacitors of the same type.

2. Make sure the button is working. It could have gone wrong too. You can test it by disconnecting the connector of the button (it is connected to two small pins) and connect the pins manually with some metal object or the end of a screwdriver for a moment. If the pc turns off the button is faulty.

3. If these suggestions wont help some people reported that putting the whole motherboard in the oven for a specific time on a given temperature can fix things.
