HP/Compaq :: Dv9700power Cycles On And Off Repeatedly
Dec 27, 2009
A friend gave me his HP Laptop to look at. When the power button is depressed, the power will cycle on/off repeatedly - on for 3 sec. off for 5 sec.
The only way to power down the laptop is to unplug the power cord and then remove the battery.
When the laptop is in the "power cycle" I will hear one "clunk" coming from the vicinity of the DVD player although it could be from the cooling fan.
There is absolutely no display and the only way I have found to break the power cycling without removing the cord and battery is to depress the LEFT SIDE CTL & ALT keys 4 times as the power cycle is first begining. This will cause the power to remain on. However, NOTING else will happen. No display, nothing loading from bios or HD etc. I can open the DVD drive and insert a CD/DVD and the drive will wind up but nothing will happen.
The exact same thing will occur with the RAM alternated or removed completely. It will also occur with the HD removed. It also occurs with the RAM & the HD removed at the same time.

So earlier this year the original battery in my black MacBook died on me. Machine is out of warranty, but took it in to the Apple store anyway, and they ended up replacing it for free. Well THIS battery only has 40 load cycles on it, and it looks like its dead now too. MagSafe adapter plugged in, green light, battery indicating its not charging. I've pulled the battery out, checked pins on the power adapter (hooked it up on a friends MacBook to be sure it wasnt the adapter, and it did charge).

Just got my first laptop, and my wife likes using it on battery in her favorite chair whereas I prefer to sit it on the coffee table plugged into the outlet. So we end up charging it up when I use it, and only draining it to between 90 and 50% or so when she uses it. Is this okay to do, should I fully drain it once a month or so, am I being too paranoid about taking care of it?

I have an aspire 3510 which when switched on goes straight into a loop of turning on for 2 seconds (the fan starts) then turning off and repeating this on/off cycle continuously. It never gets to diplay anything on screen. I have tried the disconnect all power and press the power button for 60 seconds, replaced the memory and stripped the laptop down re seating the cpu and cleaning the fan.

I have just purchased an Acer Aspire E5-511, it repeatedly loses internet connection (wifi) despite still showing as being connected. I have read that numerous other people have experienced this problem but I have not found a solution that works. I have tried updating the driver and changing the battery power settings etc. I have spent ages transferring all my files accross so am reluctant to have to send it back now.

Does anyone have a good way to OC this laptop other than using ClockGen? I am basically wondering if there is a BIOS option. I know there are some OC guides out there, but this laptop is almost 3 years old, and as far as I can tell does not have an option in the BIOS. Also, my proc is the T2600, not the one is this review, but other than that exactly the same. I am looking to play around with this because it is old and I dont care too much if I fry it since my new hotness is on the way.

1. How do I make it so the volume 'screen' (the little pop-up) doesn't show up when I chance the volume?
2. Is there a way to completely remove and disable the fingerprint reader?
I'm using Vista Home Premium 64 bit.

By the looks of the bottom of my laptop it seems it might be mxm compatible as there are lots of removable pieces... including one that looks alot like an mxm slot. I know that this laptop can be configured to come with the 9200m. This is a fairly brand new model but could someone tell me whether this thin is mxm compatible?

Ive just about had it with Vista on my laptop and want to try a new OS before I junk this thing. Is anyone running Win7 or Ubuntu on a HP DV5z AMD 64 bit laptop? The machine is about a year old and I have 4gb of RAM and the thing is a dog. Ive used Ubuntu in the past on Dell laptops and its a pain to get everything running wireless drivers, flash, etc. Win7 being a RC may or may not have everything up to speed on for my machine.
So, if you have Win7 or Ubuntu on a HP DV5z please give me a shout, good or bad.

Can't really see much difference in these models....looking at Best Buy
Other than 17 vs 16 inch screen are their any benefits to build quality from 1 to the other?
I will be travelling so I would prefer the lesser HDX 16 incher but build quality is a concern
I travel by plane, train, bus every weekend so it needs to be able to handle a little beating

I'm am deciding whether to buy this laptop for school use. It has a great size, stylish, and decent specs for a laptop that is so lightweight. The only turn off is that it was made for entertainment, but should this laptop do well for word processing, spreadsheets, and web surfing?
Would the 9 cell battery last for more than 5-6 hours? My budget is also under 700$ but it can stretch a little.

I'm heading off to school, and these stylish, affordable notebooks have caught my eyes. The only problem is that I only get 2-3 hours of battery life on these notebooks although I can buy an extra battery. What I"m mainly doing is word processing, spreadsheets, iTunes, and web browsing but not all at the same time.
Here are my main questions and concerns:
Do these notebooks have good build quality?Is there any other way to charge the battery without having it in the notebook?Do they get hot?
I may have more questions to ask later.
I am buying this notebook in Canada.
Seeing that the battery tests I've seen on some reviews, they are surfing the internet with Wi-Fi on. I will not be, I'll usually be word processing. Should it last maybe 3 hours?
How long does the 9 cell last on the DV3?

I own a DV7-1038CA, I actually decided to buy it after reading what people said about the DV7s on this forum. Unfortunately I have a problem .
I had opened up my DV7 to clean out the fan ( ****load of dust in there) and took the whole laptop apart. I put it back together and it worked perfectly fine for about 10 hours. The laptop worked great until I dropped it down on my table at a height of about 1 1/2 inches, not a significant height but the screen immediately turned white and the laptop shut off completely. It would not turn on at all, the power light would blink for less than a second and turn off and then I'd have to wait 30 seconds before I could get it to blink again.
I then took the laptop apart again and this time I checked if everything was plugged in properly. I decided to leave the unnecessary covers off so I could turn it on without having to screw it all back on, it turned for about 3 seconds....before I noticed the display cable to my screen was on the heat sink and had caught fire. I immediately turned it off but the damage had already been done, the fire had burnt through the wiring on the inside of the cable rendering my screen useless ( whenever it was plugged the charging light on the side of the laptop would turn off). At this point the laptop was turning on but would turn off after about 5 seconds (probably due to the fact that there was no screen) During this little fiasco I had ripped off the ZIF cable that connects the power button board to the Motherboard. So now I had no way to turn my laptop on, I ordered a new screen and a new power button board.......

Looked at the HP DV6 today at circuit while browsing liquidation sales. Looks like a nice laptop. 16inch screen is nice, looks like less vertical screen but web pages look nice. Just a DV5 with a bigger screen?
