Powering Up Issue. (Laptop - HP)

Dec 7, 2016 5:32PM PST

I've had this issue on monday where I tried to turn on my laptop, the power light came on but for 10-20sec the light goes out. Usually when I press the power button, windows will start up but it didn't. I tried swapping on the cable for the battery, It turn on. I shut down and remove the batt for the power cable. Laptop turn on normally.

Just now, I tried turning the laptop, same thing happen but this time I tried to power up the laptop with cable and battery nothing happen. for a hour or so I powering up a few times and nothing happen, only moment ago I manage to power up the laptop. You or anyone experience this before?

The condition of my laptop: it's about 5 years old, I got my harddisk change early this year.

Clarification Request
Is the battery 5 years old?
Dec 7, 2016 6:20PM PST

Old batteries can fry the charger, charging circuit or motherboard. I don't know why folk think old batteries are worth frying the entire laptop but you see it all the time.

Now test without the battery. If it works, well, it's better than a fried laptop.

I never use battery.

Hey, Nope. I never used the battery since the day i bought the laptop.
Laptop never leaves the house, so I only use power cable.

I got a 3rd party power cable a couple of weeks ago when my HP power cable went dead.

And that's no good either.

That battery smooths out bumps in the power system. Sounds like it's time to get estimates or just move on.

Batteries don't age well either. So if you didn't use it, it can expire over time. Folks and batteries explode over this.

Right now, there's no battery pluck into my laptop, the only thing that's powering
the laptop is the power cable.

And if that works.

Go with it. It held up for 5 years so that's a good lifespan for a laptop today.

That's good to hear, but...
Dec 7, 2016 6:59PM PST

I'm still not sure whats wrong with my laptop and why it refused to power up. Sad

I'm missing the model number.

It's eluding me in this post. There are models like the TX1/2, DV6000/9000 that do die over time and well known why. That's just a google to find out why. The failure while known does not mean you should fix it.

- a HP Pavilion DV4.

The DV4 is a series.

Even so, the usual fix is a new motherboard.

Did you try a new CMOS battery, just in case it's a cheap part.

I did get my CMOS batt change together when I replace my HDD.
I had this "Boot" screen sometimes... I press Enter and the laptop start up with older date such as "2011". I had to resync the time and restart due to some apps missing, a restart usually fix it.

The clock failure would have me
Dec 9, 2016 6:44AM PST

Pop in a new CMOS battery. That's the cheapest part it can be so as long as it loses the date, it's either that or the motherboard.

Now I did encounter machines that would corrupt the BIOS but fixing the bad battery helped. I get the feeling you are looking for a cheap fix like the CMOS battery.

As you are into PC repair, get out the Volt meter and measure the CMOS battery before and after a new battery. What did you read?

I'm not very good at fixing PC, but I do read about the faults as it happens. I might take it to the same place where I had my Laptop HDD fix (early this year). I'm doubtful if they'll give me a proper fix but its the closest Laptop/PC fixing stores (plus I don't have a Volt meter).

I missed where you replaced anything.
Dec 10, 2016 8:08AM PST

I've shared a few things about old or missing parts and here we are at many posts.

OK, no Volt meter so can you recap what you've replaced so far?

If nothing, just tell. Here the CMOS battery is the cheapest thing it could be. What's next costs a lot more and this is why I'd just change it.

Once in a while a client or member will want an absolute this is going to fix it answer. For those we quote out all the parts that are suspect rather than giving the cheap possible item a try.

Replaced Item
Dec 10, 2016 4:32PM PST

I had my HDD replaced early this year due to very slow start up and and responses time, I also had my CMOS battery change as the time & date kept getting mess up everytime I power up my Laptop.

I also bought a package at the Laptop repair shop, in which they'll do a "cleaning of my laptop parts" thermal paste, laptop fan cleaning and some others that I've forgotten.

I've also recently change my power cable.

So, that's 3 items. Power cable, HDD & CMOS battery.

So with those parts it's still broken.
Dec 10, 2016 5:00PM PST

It's a laptop still missing the big main battery and now that all that work is done and it's still failing your repair shop should quote out the last two parts. Motherboard and battery.

Dec 10, 2016 11:44PM PST

what you're saying is that the could be either CMOS, Main battery (plug-in ver) or it might be the motherboard that's causing issue with me starting up the laptop, yup?

- Collapse -
I thought you popped in a new CMOS battery.
Dec 11, 2016 8:03AM PST

My view is we should try the cheapest thing it could be even when the odds are against us. Now you are asking me if it can be that so I worry you are fibbing to me it was changed with a new one.

At that point it's something else. Get estimates.

- Collapse -
Oh no.
Dec 11, 2016 8:33PM PST

You got me wrong, right now, I'm getting all the info I can on Why I've been getting the fail start up and what to do when the next fail start up happen and. Yes, I will be getting a new CMOS batt at a Fix' it store.

My bad if it got confusing for you. Silly

It appears I read it right after all.
Dec 11, 2016 8:43PM PST

The CMOS battery is the cheapest thing it could be. I run across folk that demand I get it right and won't risk what is a 25 cent part here. I know folk pay a dollar for them but at the office we buy in a 10 pack for about 4 bucks.

I wish we had a chance to discuss what happens after the cheapest part but I understand folk want "correct" diagnosis. I run across all types out there and for those that don't try, we have to give them the highest estimates. Otherwise they will get mad when a 25 cent try doesn't pay out.

Battery replacement
Dec 12, 2016 5:28PM PST

I'm definitely will change the CMOS batt for starter, I won't want to risk destroying my laptop over a cheap replacement, as for what happens next after that?

I'm not a good techgeek hence I'm more afraid of destroying my laptop due to my lack of knowledge with laptop/pc fixing.

My laptop has this message pop up once a week "The CMOS checksum is invalid - CMOS Reset (502) " It's due to the CMOS battery being faulty is it?

- Collapse -
Since you feel it's risky.
Dec 13, 2016 11:49AM PST

It's time to take it to the repair shop.

We are at 20+ posts and the cheapest thing it could be was not done so I have to pull the plug on this laptop.

Hope the shop doesn't ding you too hard.

Thanks! :)

Thanks for the advise, I hope so too.
Have a great week ahead & a wonderful X'mas. Happy
