HP/Compaq :: Dv5t Excessive Battery Wear
Jan 16, 2010
Does anybody else with a dv5t have excessive battery wear? I purchased the laptop in August of 2008. According to hwmonitor my battery can only hold 30758 mwh down from the designed capacity of 47520 mwh. I rarely used the battery. Maybe once a week for 5 minutes to move the laptop.
I asked a friend with a dv5t purchased around the same time and his capacity is down to nearly 27000 mwh. Our laptops are the same except his has the intel integrated graphics while i got the 9600m gt. Also he uses the battery almost daily.
When i first got the laptop i got nearly 2 hours out of it. Now i can barely get an hour.
We both calibrated our batteries a few times by fully discharging and fully charging a few times which did nothing.
I know that batteries experience wear but does this seem excessive? I believe the estimate is about 10% a year. But this is almost 50% wear in a year and a half.

I last used my DM3 about 2 1/2 weeks ago. When I shut it down the battery was at 100%. When I powered it up today, I had only 58% battery charge. This drain seemed excessive to me so I called HP and they seem to have agreed with me as they are sending me a new battery for free under warranty.
Anyone else notice excessive battery drain when the unit is shut down?

I got my hp dv6 last Monday, so it's quite new. About three days ago I downloaded System Information for Windows trying to find out which was my GPU temp(what I didn't find, it only shows only HDD and CPU temp) and looking other stuff I noticed that my battery wear off was 7% while the battery is(was?) also new, so it got me preoccupied, so I checked it again yesterday and it was 9%!, I checked today and it's at 10% . Just c'mon I don't dedicate all my free time to plug and unplug the battery ,so why the fcuk(note there's no grammatical error) it wears off so quickly,

I have a Pavilion dv6345us that I got back in June 2007 and I like the notebook but one of the main problems is that it keeps messing up the batteries.
The battery it came with ended up dying completely (doesn't hold a charge) within a year or so. Then I bought a 12-cell battery off eBay (generic brand) last summer/fall and now that battery too is almost completely dead.
I don't know if its a problem with the laptop or the battery so I don't know what to do. One thing I do notice is that the computer heats up a lot frequently so maybe that is the reason for the battery wear?
Only thing I have done to the computer is upgrade to 2GB RAM from the 1GB RAM it came with, a month after I bought it.

I am looking into getting one of the new macbook pro's. Though I must say the non removable battery does concern me a bit. In past laptops I have had, I without a doubt saw increased battery wear and tear when I left the batter in the laptop while the laptop itself was plugged in. I completly destroyed a battery on my Dell laptop by doing this for about a month when it was asking as a desktop. I took the laptop which used to get around 4 hrs of battery life and then after a month it got no more than 15 minutes.
So after that I always took the battery out, so now with the new macbook pro's you cannot take the batteries out, so wont the batteries wear down to nothing faster than if you took them out when not using them?

I have an Acer 4810TZ timeline (SU4100 processor). I had charged the battery up to 100% and then left on an 11 day vacation. When I came back, I found the battery to have only a 16.7% charge left on it. Is this an excessive lost of battery over an 11 day period? My laptop was left shut down (it was not in sleep or hibernate mode). I would think the drain on the battery would be minimal.
Is my battery defective or is this normal? I've had the laptop for about 2 months.

here we go, acer 3810tz :
1.Laptop turned off -> charger unplugged -> turned on after 15h, battery bar:
99,99-93,0= 6,99% of drain
2.Laptop turned off -> charger stays plugged -> turned on after 15h, battery bar:
99,7-99,0= 0,7% of drain
3.Charger unplugged (laptop goes to on battery mode) -> laptop turned off ->
-> turned on after 48h, battery bar:
98,0-97,0= 1,0% of drain
Conclusion:
There seems to be a bug in BIOS power managment, so:
1. Unplug charger, laptop goes to on battery mode (green leaf).
2. Turn off laptop

My dv5t won't take a charge. The charge indicator light does not come on and the battery charge indicator graphic in windows doesn't show it is charging (plus the AC adapter isn't getting warm). My laptop is now out of charge and I have no way to use it. I think the connector at the PC end might be loose or something, but perhaps it is just the AC charge adapter.
The reason I say the conenctor at the laptop end might be loose it because I can wiggle the charging plug around in the socket quite a bit when it is plugged into the laptop power socket (the round socket at the rear of the right side). Sometimes the charge plug has weight on it when in my lap since the darn things sticks out so much, and I am wondering if I have caused the socket to malfunction internally (loose lead or something?).

My battery will not charge even though I just got it about 2-3 months ago from HP while my laptop was still under warranty. When I hover over the battery status it tells me 0% available (plugged in, charging) but no matter what I do it won't charge. I've tried charging this battery on my other dv5t with a different AC adapter, but the same thing is happening. Are there any tricks or anything that I can do? This is a new battery and for it to die after 2-3 months just doesn't make sense. HP battery check tells me the battery health is Good.

Just a heads up to all the studio XPS owners. I opened up HWmonitor to check some temps and I noted the battery wear level and its 23%! I have only had the laptop since mid February and its degraded this bad very quickly. Needless to say I will be calling Dell and getting a replacement.
But I thought I would bring it to the attention of the community, because its been so helpful for me I try to give back.

I bought my Dell Inspiron 1545 about 6 days ago, I decided to install windows XP and drop vista in-order to save the battery life from vista hungry resources but
it didn't go very well i get about 2.15 hours max (with only firefox running and a LAN connection cable plus i shutdown wireless+bluetooth).
from the battery under windows XP, then i read about vista/windows 7 that they have better power management than the ancient XP so i installed the vista basic that came with the laptop but when i measure the battery's wear level which was too late i found out this:
System information for windows: <br />
Battery Bar: <br /> .....

Is it normal if BatteryBar is telling me I have 6% wear on my 6-cell if the laptop is only a month and half old?

I have a utility reccommended here called BatteryBar. It has a category called Battery wear. What is battery wear? Is it as it sounds, a degradation of the maximum potential of a battery over time? Is there particular actions that cause an increase in battery wear?
I have a 1 week old Acer 1810T. Up until now the battery wear has been 0.0%. However, I let the battery run down to the point that the computer shutdown. I thought this was a good thing. I know in the old days batteries would develop a memory. They recommended a occasion full run down and charge. I think I read this is not true for the Lithium battery, however.
Well, after restarting my computer I see my battery wear is now at 1.4%. Is this because I let it run down? Also, if I want to my battery to last as long as it can, is it better to take it out when using it at home on AC power? That is about 90% of my usage.

The DV5T is one of two notebooks that I'm considering and I have a question related to the heat while gaming. Many have recommended a cooling pad, and many also suggest simply raising the notebook .5-1" in the back. With the natural lift of the 12 cell battery, would the cooling pad still be necessary for long gaming runs? I don't want to pay the extra $20 for the 12 cell only for minimal cooling gains and still needing to buy a cooling pad. Or is it cooling pads are highly recommending for all laptops when gaming?

I am buying a dv5t off ebay but none of the laptops on there come wit the high capacity 6 cell battery offered on HP's website. Is there any place I can buy one? I've tried ebay but it doesn't appear there are any on there.
Also, model number or serialnumber for the high capacity 6 cell so I can check online for it that way.

I've been looking at the 12 cell battery to go along with my dv5t for the extra battery life. I know that the 12 cells battery raises the back part of the dv5t up quite some bit. Would that negate or 'contradict' the use of the colling fan (Zalman NC1000). Since the battery pack is elevate, the full laptop wouldn't be able to make contact with the cooling fan, correct?

I saw some posts about batteries here and thought I might inquire about it for the sxps 1640.
I received my laptop July 2009, along with a new 9-cell battery.
so far, hwinfo32 has determined there is about 6% battery wear.

I bought this laptop 5 months ago and I have been monitoring it slowly deteriorating by battery life, it is a 6 cell 4400mAh battery and I use it every day, and make sure not to let it drop below 10% battery power as to not do full discharges and only partial.
I was getting 1hr 50 mins when I first got the laptop which may have been max or min settings I cant remember but anyways which seems not as good as the advertised 2.5 hr battery but I can understand that advertised and actual may differ and max, min would have had an effect. Anyways now after 5 months (Purchased early december) I am only getting 58 mins on full charge at minimum settings, now this does seem quite ridiculous and NHC is reporting 49% wear level.
My question is, is this normal for a Li-Ion Acer battery after 5 months, it seems quite bad to me, and all I can think is the laptop was left on the shelf for a while before i bought it, or that it is defective. I rang acer warranty support and I feel quite fobbed off with them saying this is normal and usage patterns and that their warranty for batteries only last 6 months and I should expect only to get 1/4 of the full charge i did when i purchased after 6 months. So acer is in the business of making low quality batteries?

my Sony Vaio FE690 only lasts around 30 min on battery (I tried calibrating, still same life) but every utility that I try (Battery Eater, Notebook control, Everest, etc.) reports a wear level of 0% and a full charge capacity that is the same as the original capacity.
Can anyone confirm that the Sony battery firmware does not report the wear level? I'm wondering if it has something to do with my BIOS upgrade.

For the past few weeks my DV5 has been behaving oddly when booted up from a cold start. The fan switches on producing an incredibly annoying rattle and squeal that almost sounds as if a bearing has gone in it. It's the same noise you occasionally hear from desktop fans that are clogged with dust and gunk.
It usually lasts for only a few seconds on initial bootup and is all over by the time Vista loads.
However, this laptop spends 95% of its time on my desk in my dorm room, residing on an improvised laptop stand for better cooling. I took it into the shop I bought it from now that I'm home and whilst they were happy to look at it, it just wouldn't replicate what I had been describing to them when they were listening to it. Murphy's law I guess. Anyway, they thought the only way to sort it out would be to leave it with them and they would try it daily till it it reared its head. Not knowing how long it would take to get over its stage fright (and needing some information off it) I declined that offer!
Has anyone noticed similar traits or symptoms in their machines? If so, how did you remedy it? I'm really tempted to pull it apart myself but it is only 7 months old so well within the warranty period that I may put in jeopardy.

I have a brand new DV7, and I've noticed that when I insert either Blu-ray or DVD-ROM disk, the computer gets very bogged down for about 5 minutes, and there's no recognition of the disk being there. There's no disk driving "whirring", and I can't explore the contents of the drive. Then, 5 minutes later, the drive whirs up and and the computer seems completely normal. This is bascially an out-of-the-box problem in terms of possible spyware, virus, etc. It's as if the insertion of the disk puts it in a coma for 5 mintues.

I attached two pictures for reference. The first picture is about 1 month from brand new. The second picture is today, about 5 months from new.
Now I do expect eventual wear. Wear happens. However, I generally expect to get a good amount of use out of a product before the wear occurs. I had a Dell 9300 for 3-4 years. Its keyboard has less (cosmetic) wear then my HP at 1/10 the time frame. I literally have to wear down the key to make the key unreadable. With the HP, they just use a light coating of silver over the black plastic that just wears off readily easily, too easily for my taste.
I know I'm not the only one that has this, but I'm curious what everyone else is experiencing as well. As it stands now, my A, S, D, E, N, O, and space bar all have visible wear off of the silver coating.

I recently bought a Dv5T with the high capacity 6-cell battery.
asdasdasd
However, I recently noticed in linux that the battery is displaying this data:
Product: Primary
Status: Charging
Percentage charge: 98.0%
Vendor: Hewlett-Packard
Technology: Nickel metal hydride
Serial number:
Model: Primary
Charge time: 9 minutes
Capacity: 52% (Poor)
Current charge: 33.4 Wh
Last full charge: 33.9 Wh
Design charge: 64.8 Wh
I'm concerned with the capacity information. Is this normal?

I just got a new Dell XPS m1530:
2.5 Ghz
4 Gb RAM
300 Gb HDD
Geforce 8600
Vista Premium
I noticed that I can hear the hard drive spinning (like that little clicking sound it makes) almost like 70% of the time. Is that normal? I tried killing off some applications but it doesn't stop! Is there any way to find which application is doing this, is this even normal?

I have been trying to read thru the gazillion posts in the 14z owner's lounge - but there are too many! Anyways, I have decided to sell my ASUS G50Vt so I'm thinking about a Studio 14z.
About the only drawback I can think of is several reviewers have commented that the keyboard flexes too much.

Is the fan meant to blow air of the back vent on the bottom of the DV5t?
Air blows out of the side vent but very little air blows out the back vent even when gaming. Im worried the vent is blocked.
Im concerned because the CPU reaches 85c when playing games, which seems a bit high for a CPU in my opinion.
