Question about HP Envy dv7-7227cl Laptop
I own 4 of these laptops. The first several months were good. My 3 teenage daughters and I are all advanced computer users. They absolutely know not to use the laptop on your lap. It blocks the vents for the fans and causes the computer to heat up. I maintain all of our computers keeping the vents cleaned and generally making sure all is running well. Replacement costs generally come out of my pocket. Though the laptops have been intelligently and well cared for, 3 of the 4 are now having heating problems. Once you start looking into it, you learn that most of the DV series has heating problems and the DV7 is no exception. We are using laptop bases that have fans in it blowing up on the bottom. Sadly the video chip has not fan, no heat sink and no vents. It is very common to lose these mainboards due to this. The computer starts but the video is black. Single blinking caps lock light means the processor has a problem. Again it generally isn't the processor but the video chip. Even with all my effort, this happened to me today. The repair guy at the computer shop tried to "reflow" the chip but no luck. The board is trash. I'm trying to figure out what I can do to keep the other computers from being complete losses as well. I invite anyone having a problem with this machine where the screen is black, the caps lock light blinks continuously while the wireless light remains amber to add your experience to the thread at HP forums http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/HP-Envy-DV7-7227cl-Black-Screen-No-Boot-No-Caps-Lock/td-p/2707879 Also click my user name take_the_train and add me as a friend in the HP user forums.

No bLink codes stated, post the code dont tell me what it means please. OK?
no year stated, no full model number stated, (service tag facts !!!)
no fans speeds stated or cpu/gpu chips, (run the program lean to use it.
no OS stated, W7? only need this to match good support software.
now the year, is this 2008 laptops from H3LL??
THE INFAMOUS NVIDIA SOLD BALLS FROM H3LL>?
no full part number so how can any expert help.
the service tag has numbers the 7227 is series, and CL is a country ,no country stated, some use different parts,!!! inside !!!
DV7-7227cl (best i can tell made 2012 so is not chopped liver old.
p./n?????????? what? the P/n will tell me if you GPU is junk.
so HP can't help
your link puts me in water damaged PC, why ask this? at all.
water kills all electronics, dead. and is new mobo time or at the least new keyboad time captain obvious to a fault.
but what is wrong with yours, ever try asking a living sevice tech and not a text box of blind bats?
ok i read you 10x better post at HP, gee 100x better
above is useless facts, all.
its just a laptop and all fail, and all do so fast, due to abuse mostly
spilled drinks, dropping them , hitting them, kicking them and well what all things that are portable do, like the old commerial
for American tourister luggage and that gorilla commercial on tv
(I dont watch TV now,so who knows how)
But lets pretend the its not damage, by man. caused
lets pretend the heat is bad and your 80c single word there
tells it all, that is too high, the processors self halt at 90C
only your 80c , word was any use to me, must one word. that.
read the intel '/amd spec yet, have it to read want it?
in fact it even throttles its self (lowers clock speeds) too hot.
so do all AMD do that. (for obvious reasons, saves it self from destruction !)
the slower it goes the lower then heat (laws of CMOS, ask)
The heat is very hard to manage in all laptops of this era.
early 2000s. to mid. (much much better now)
(5 makers PC all same chips same speed class all 5 love to overheat.
or is it the solder ball deal.... 3 causes. there.
vents, clogged inside, or fan failing or solderball issue 2008
the reason you dont know is , 1, did the processor self halt?
i bet that is what it DID,
gaming, most laps are not GAMING ready , at all.
The temp didnt lie to you as you alluded, the chips report temperatatures, very accurately, far more accurate than is EVER NEEDED BY ANYONE accurate. ok?
it's not a rocket.
so you have been fighting this for 3 years , gave up at HP and come to fixya for magic blind help, that it?
tell you what,.
does the screen act up if you flex the screen gently with 2 hands.
does it same with base flexed, or pushing ******* the J Key.
yes, that is solderball failure. 2008 again no year pc stated
and no full p/n stated by you and matter if its the Nvidia chip.
the problem is your not telling the full service tag
ever go to hp parts surfer and look at the vast number of
see that>? all with different mobo and up to 3 or more video chip versions and 3 screen types. and matters what you have.
here is my guess if not the solder ball problems ill make a list.
1: stop playing high end games, they are too much stress.
buy or make a real gaming desktop and WIN ! or a super expensive laptop rated as such (super hard to design!!!) and not overheat. (lots of heat in a small space is problematic you should know that as an engineer, ?)
I have a program called stress it, that will overheat any PC made
(learn from that fact)
2: remove the heatsink and clean the RAD there. it will be packed in FILTH (dust/lint/air/dirt/filt) im sure you never looked once.
seen first off your support page is read., SEE THAT RAD THERE???????
one more, lots of overheating here on all pCs, all overheat if you work on PC and know them well. all do , #1 is here, look read.
3: then put all that back and use the good compound from japan seen here. the best of the best (my testing) see last link in my long post, (its long due to no testing by you, or full service by you)
My SHIN grease is TOPS ! (forget articool lies) this is IT !!
i tested it. !
learn to that i5 slug CPU any grease works, see?
4: remove hdd and put in super cool SSD drive. way less heat expelled inside any laptop doing this, and helps.
5: use a base fan plate LT sits on. ( I see you do but here for accuracy and completeness.... for all readers, DIG?
6: run the temp monitor program for all cores, and set the RPM higher, mine allows me to have 5 RPM settings. at 5 different temperature thresholds. or just 1, at 60C run fans max RPM.
works. very well , get the heat from the cores to the room you are in, make sure room is not at 120f already. (if in a barn and AZ)
ok., me lucky and you,this time, only 2 sub models DV7-7227cl
not 50 or more as is usually the case. so only 2 mobo here.
the below is my toss coin on yours.
MOTHERBOARD UNIFIED MEMORY ARCHITECTURE A70M W8STD
AMD A10-4600M Quad-Core processor with Radeon HD 7660G graphics - 3.20GHz/2.30GHz (4.0MB Level-2 cache, 1600MHz DDR3, 35W TDP) - Includes replacement thermal material
official HP page on that.......
if this is your mobo then its not NVIDIA or solderballs.
just pure raw heat. (Im answering as I find out what is actually inside that box of yours.... so... follow on and learn how i did that.
so what are the A10 heat max levels, 90c? logging them?
what are the RAdeon HD temps> 90C?
we keep ours at 50 to 60C or take actions.
this post is long. only from the lack of clear inputs tests and all temp logs posted, from power on to SIMS crash.
actions taken besides bottom fan, plate.
ever get one bad Laptop fully serviced for this heat issue, seems NOT. I could fix it, but you will not pay me.
so you get to learn how to get the heat out your self.
I own no A10s sorry can not tell what it takes to make it work
but i can tell you id be all over the RAD , SINK and compounds like tick on hunting dog.
here is i7, 2010 era
runs too hot. i5 is slug and cool all day long, I have many of these.. all versions I have if the 8540w/p, a great HP LT.
to get that cooler, (the fix on mine is just like others)
off came that HS and heat pipes.
cleaned RAD , most are HORRID there.
and put in the shin magic.(last link)
found the HP grease there turned to like old dried glue.
100% useless that. totally bad. bad grease there.
in my case it was 5 years old at the time. and failed.
Many PC's made, have defective grease. (HS grease)
HP calls it TIM ! "thermal interface material": wow !
(Heat sink compounds are not all equal)
here is my brand of greases,.SHIN SHIN< SHIN get SHIN !
I use X23-7762
find it on fleabay, make sure its not fake, as Ebay sellers 1/2 are crooks there. make sure the syringe looks legit, from
I learned (hard knocks) that on the hottest processors only this worked. (tried like 10 top brands, most are clones of junk)

I understand your problem completely and I also use the laptop trays that have fans to force air into them and they range from useless to effective in doing there job , I have found that many laptops will need to be opened up to really clean out the dust to prevent heat build up as it gets sucked into the machine covering and blocking things and just cleaning the vents from the outside is not enough ,I also use a external fan that can be purchased as a small desk fan (around $10:00)that I use to blow air directly into the intake vents and I also use 4 plastic bottle tops that I hot glue to the bottom of the laptop just to raise the height up a little to maximise air flow , and yes indeed the laptops that you have do seem to be problematic with heating issues and other than trying to run them next to a AC unit that is bowing air at a temp that is a few degrees cooler than what it actually is ! and during winter the heated air temp is not going to do much in the way of cooling .Dust , lack of care from uses, and poorly manufactured equipment is 95% of heating problems , so best of luck, as it looks like you have done your best to maintain the laptops but the DV series has let you down and I am sure this will influence you on your next brand of laptop that you buy.

I will ask that you do this, format your PC and this are the step if you don't know... Go to the control panel you will see backup and recovery, buy an empty disk backup all files, then format your PC and recover after. All will now be fine. check
