An alternate way to 'Power On' HTC Desire?

Hi!
I managed to break my Power-button, while phone was off, and how I can't' really get it on again.
So my question is; Is there any alternate way of turning my HTC Desire on, instead of the Power Button?
Thanks in advance;
CjC

i dont know much about hardware hacking on the desire
but i think there isnt much you can change because this is so low level that no software hack could fix it
so your only opinion is you let it fix by customer support or by disassemble and fix it by yourself
as i said i am not very into that materia, so i could be wrong to but i dont think so ^^
best wishes

Hi!
Thanks for answer : )
Ye I already tried do disassemble it on my own, and from that I bent one of the pins to the battery haha : (
But I fixed it, but my power-button is still f***ed...
So I have a working non-working Deisre atm ^^

a buton is just a button.. if you can locate the button (well not the plastic, the phisical hardware) you will see that there are 2 wires coming out from it.
you just need to short circuit them (hey that's not a bad thing! that means making a bridge for let current pass even if the button is opened)
That can be DIFFICOULT, the solderings can be small or there cannot even be soldering but just copper pattern under fiber. In that case you can use a tiny knife to peel off the glass fiber for reveal the copper but can be dangerous, you can cut the copper extending the damage.
if you are good in electronic if you can turn it on with just a whire or a screwdriver as I says you can take a mouse button (as this http://www.soselectronic.com/a_info/img_data/h/dts31.jpg) and make it your default one, but it will be ugly, difficoult and maybe it will need some maintenance.
trying with the warranty is free and I think that it is valid!
let us say what they tell to you.
hope I helped you mate! ask more if you need

if you manage to boot your desire you are safe
that and in the boot menu is the only thing you realy need the power button
after that you can simply mod a trackpad to wake/unlock into your rom and use a widget to go to lockscreen
than you only have to watch your battery so your desire doesnt run out of power

Yes you did help alot with this answer, but unfortunately, I ain't no electrician!
Your advice with the picture was good, but I don't really know where to get one of thoose. I ain't no genius when it comes to smarth-phones, and my I broke the void on my phone so...
But I didn't quite udnerstand the short-circuit thing.
can you explain?
There are no wires coming out of the button :\

Hehe, I know, but how can I boot it with no powerbutton?
Nor can I enter recovery-mode with no powerbutton!
But thansk for your answer!

well sorry i'm half electrician so i can explayn things in difficoult way.
well starting on the short circuit thing:
it means close the contact, in simpler words when you press the button it just makes 2 contacts to touch each other
so the sys will see that there's a current flow and he thinks ("uhm button is closed better startup")
I'm watching some photos at desire breakoff and i can see that it is a sort of smd in a small case.
So now I may suggest you to don't make nothing, finding the contacts for who have a medium knoweleadge of electronic devices can be pretty simple, and using a screwdriver it can turn your phone on.
I cannot tell to you if it's possible coz I haven't teared it apart yet.
BTW after the first startup you will need an application that will let you lock and unlock the phone via the volume key (it exist) and eventually some jumpers for turning it on again. it will be pretty scary for who is not "in the field"
by the way i found this thing
http://mobilehq.com.au/productDetail.aspx?productID=20225
it may interest you... and the photos are too small for see the button type, especially from behind where is there thay maybethe button is soldered on the board by Those things (URL)
just locate the correct 2 and it's done. usually ther are just 2 on mouses.
oh the micro buttons are reperible in any electric store (even smaller but without the "push and he will come up by himself" effect) or inside a pc mouse (broken is better) switch never* broke down on a mouse and there are at least 3
but they may be too big.
what about the warranty?

thanks button if i'm helping helps

Possible temporary solution
So i know this is quite late but I stumbled on this trying to find a solution and I'm sure there's a chance others might too. I have this issue on my HTC 610, and I found that pressing and holding down the volume buttons at the same time turned it on. Hope this helps anyone else who has a similar issue

SO FRUSTRATED. New LCD installed, black screen issue.

Hey guys how are you!
So my beloved evo's lcd broke and i just replaced it today. The strangest thing is happening.. the screen turns on fine, but once I turn it off, it wont turn back on. The three buttons at the bottom light up and the screen, i can tell, turns on. But I cant see the UI. It is definitely not a software issue and I have tried reseating the ribbon cable multiple times. What the hell? Is my evo too old? only way i can make it work is with a reboot which is super annoying.

I have one with a shattered screen I will be replacing soon. If my memory serves me correctly there are several different types of ribbon sizes. Hopefully that is not your issue. I would suggest using a bright light and looking into the female receptacle (no dirty jokes please) and make sure that nothing is bent or twisted. Also check cable that none of the connections are not chipped.
Not sure if this will help but it is worth a shot. Other than that I am not sure what could be wrong.
Peace,
Love, and
Happiness
Edit: well fine honda but just one and you have to promise that it will be clean

The screen turns on fine. Its something I've never seen or heard about.

Well what caused the problem in the first place? Did ir just stop working or was it an innocent victim lacking the proper protective coverings?
Either way there could be more hardware problems than your screen. Give this a try and tell me what happens. Plug your phone into the charger, if nothing happens with the screen try connecting to your pc, and if still nothing try a rom that has the volume keys to wake aokp/cm are a couple that I know have that option.
If that doesn't work I will see what else I can think of.

of course if you can't find the receptacle, you'll want to take hold of the dongle and have it cough a couple of times...let us know the outcome, please!
But seriously, so is this what happens?
You turn on the device. Powers up ok. You can see the screen. Then what? How long till it disappears? Are you doing anything when this happens? Can you unlock the phone and see the desktop? How do you know the screen turns on fine? What exactly is giving you this impression?
Sounds to me like another broken lcd. Do you have another phone you can swap out the mainboard and help isolate the problem: mainboard or lcd/digitizer/connectors.

It powers up fine and then as soon as the screen turns off (either manually by me or by timeout), it will not turn back on. The screen powers up, the lights at the bottom turns on but its a very dark grey screen. And as you said, isolating the problem would be easy if I had another mother board. I have another one with a wide flex cable IDK if should request a replacement or if i should get a more expensive, OEM LCD.

Ok questions for you.
Stock/rooted
S-on / off
Rom/kernel combo
Min/max governor
Oc/Uv
Everything thing else works
Power button (I say yes)
Volume +/-
All 4 screen buttons
All points of screen responsive
If your on a rom that supports volume wake try it
Auto brightness off/on

I did my research, man. Literally tried everything. Its not software, no setting can fix it.

Think it could just be an issue with waking? The lights coming on but just a dark gray screen has happened to me with several ROMs. Bumping up the minimum CPU speed a notch or 2 usually solves it.

I asked the seller and he said it is not oem. Do you guys think it makes a difference and if I should suck it up and buy OEM?

That's what I though at first. Hours of tweaking and research and I figured it cant be a software issue.

[Q] broken power button?

So my power button is acting up, and I think it's a hardware failure.
If the screen is on and I press the power button, the screen turns off, then back on, as if multiple key presses are being registered. If the screen is off and I press the power button, sometimes the long press power menu comes up.
I think the ribbon cable associated with the power button is failing, what do you guys think?
EDIT: just found out the power button is surface mounted to the mother board :-/ so that's a bummer if the power button is the issue.
Smith

First, and only, bump. Does anyone have any advice? I've ordered the blue plastic power button itself, but not the actual switch (I don't know how to surface mount).
I'm going to replace that. If that doesn't work, I'm not sure what else to do. Can I reflow the power switch on the motherboard somehow?
Thanks

You can get a replacement part on ebay, but it is a piece that needs to be soldered to the board. You should call local cell repair shops and see if they have the expertise to do this.

I've had this issue for the last 3 months. I've just been using the home button as power on and quick toggle screen off.

Yeah. I'll see if this button replacement works first, then I'll look into having the actual switch replaced. I'm good at soldering, but I've never surface mounted, and I don't think my phone is a good place to experiment ha. I'll start looking into repair shops.

You use your home button as the power on and off? What do you use as the home button then?

The home button.
I never said I used the home button as power off, I use a quick toggles screen off setting for that

Did the plastic button change fix your problem? I think I am having a power button problem as well just not sure.

[Q] Not-working volume rocker workaround...

Hello there nice people of Desire HD's XDA Community,
I have a somehow strange problem regarding my phone. After around 3 years my Volume Down button has stopped working. In order to turn the vol down, i have to push the Up button and then slide the bar down.
This isn't much of a problem but the real problem is that, now, I cannot enter Recovery mode if something goes wrong with my ROM. Has any of you faced something like this in the past?
Thank you for your time

If you're running a custom ROM, it probably has an advanced power menu that will allow you to reboot directly into Recovery. Just hold the power button until the power menu shows up and see what options are available. If you're using 4EXT Recovery, its Control app has a power menu that allows you to reboot into Recovery as well. If you're running CWM or TWRP, perhaps their apps have a similar option.
If your phone is off you can try connecting it to your computer and using adb to boot directly into recovery,
adb reboot recovery

hey sharksfan7... Thank you for your answers. I am familiar with all of these functions.
I was asking for something in case of the phone does not boot and there is no PC available.
Or even if some user had the same problem before and can recommend me something he/she did. Like, replace the volume rocker (although I don't think a piece of plastic is the issue. More likely some "sensor" is fried/broken)
Again, thank you for your time

If the phone won't boot, you probably need a computer.

Hi there
My vol +/- plastic broke and fell out so when i need vol down + power i use toothpick , but just before it fell out completly i noticed button has 3 pads 2 for pressing buttons and one in middle for rocking action and that one fell out completly first and after that neither vol buttons using palstic button worked, so after a while it fell out completly and i discoverwd toothpick method.
So check if buttons work when you remove big plastic bar if they do see if pads are on place, biggest black is in middle, 2 smaller for pressing near end. Or just replace whole button.

Need help in buying a new volume button...
I'm searching on ebay for a new volume button, but can't seem to decide on which one can be the best... Don't seem that most are genuine (if any at all), but I don't expect that...
Can anyone help me on this? http://www.ebay.co.uk/sch/i.html?_s..._nkw=htc+desire+hd+volume+button&LH_PrefLoc=2
When I install the new one, does it going to stay firmly attached?!?
I'm asking this, cause on the last time that I dismantle the volume button, I don't know what I did, but I never got back the volume button firmly attached again as it used to be. Now it's very loosely and it very simple to loose it from the phone and that's why I'm buying a new one... to trying to fix the volume button to work and to get it firmly attached on the phone.

Hi there,
I've got the same problem here, but my volume buttons are gone..
I've ordered one from good old china (hehe).
I think you have to set a piece of elastic glue in the center of the button to keep it in place.
At least at my phone there is a little point of glue-like stuff there, very elastic.

but do I have to put that elastic glue or does it already come with the new button that you order??
Did you already have that new button and put it on the DHD ?? If yes is it good and fits good? Where did you bought them (ebay? seller?)

Not arrived yet, will tell you then.
I think you have to organize the glue yourself..

Any news??

Yeah. Arrived this week, I just installed it. No glue delivered with the parts. And the parts aren't nearly the original, but I got two of them.
Because I'm using a cover, the volume keys didn't disappear until now.
Just took a long time to get them, next time I'm gonna spend 3-4 EUR more and order it from Germany...

Hello
I'm having an issue with the volume button too, so I'm using this thread.
I have only the down volume which is working, the up button doesn't respond whatever the ROM.
And now the button doesn't stand in place, I have to watch when i take it that the button volume stay still. (I may use some glue to fix as you wrote earlier)
Do you know what I have to change if the up is really down ?
I don't think my button is wrong, but maybe I'm wrong and there is some contact to chek before going further ?
Thank you for any help !

Power Button Issues

A friend of mine has issues where is power button is kinda loose and the power menu will always come on and so will the screen when it is off. Any way of repairing this? I cannot seem to find a guide on doing so or the right parts, does he need to just buy a new button for the power button or the whole daughterboard for it?

Probably just needs to replace the power button. I've seen this sold on places like eBay. Installation may require a pro job, however.
