Question about HP Compaq Presario R4010US (PX352UA) PC Notebook

1 Answer

No power to Compaq Presario

Was using Compaq Presario R4010US (less than 2.5 years old) with power adapter plugged in to recharge battery.  Up until this point had never had a problem with unit charging and holding a charge.  Unit went into hibernation mode and would not power back up.  I initially thought power adapter not properly plugged in but connections were tight.  Noted amber "lightening bolt" symboI on front of machine was flashing fast and then I detected a faint "acid" smell, almost like burnt plastic. No other lights on. I unplugged power adaptor but unit would not come on, probably because battery not recharged.  I removed battery and plugged power adapter back in but unit would not power up.  Instead, I saw a faint puff of smoke and possibly a spark come out from ethernet port located on back right side. (No ethernet plugged in.)  I immediately unplugged power adapter.  (Battery was not plugged in.)  This does not appear to be a good sign.  Can a power adapter (original HP model less than 2.5 years old) go bad and then fry the unit?  Will a new power adapter resolve the problem or is the smoke/electrical spark indications unit got fried?

Laptop shuts down when using battery


If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

Good day, please double check your adapter. Maybe your adapter is defective. If not you need to go to the nearest service center. Maybe your laptop has an internal problem w/ the power. tnx

Laptop will not charge and now I can't power it up


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, until they won't charge up at all.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Compaq Presario v2000 notebook reduced battery life


you may try:
1) check the battery alarm at windows power managment, to set 5-10% alarm level.
2) discharge the battery to the empty then charge longer time, you need monitoring how long it charged (see charge lights change), need to change new one if charging time much less then before(less then 10-20 minutes)..
3) plug-in AC adapter monitoring charging current,
this step you need a current meter to make a series connection in the circuite, the battery is over life cycle if the current less then 500mA.

Battery doesn't stay charged


The problem is with the battery. All Lithium batteries last for around 1000 charges or so. Since the laptop is 2-years old the battery needs to be replaced.
I Hope this solves your problem. Kindly Accept my solution.

AC Adapter Problem


why not buy the correct power pack
matching the power needs of you puter.
each puter needs a watts level, do that or more never less.
only hp.com spec tells you what you need,
its in the service guide for you PC.
take out the battery
now run OFF LINE pack
run now? good, does it drop dead if you gently
wiggle the plug at PC port> not moving pack and its cable.
yes, then the PC has a bad power port end cause.

if it is the PC power jack bad
you will never fix it. its real deep and takes totally disassembly to reach.,(done many and do no teach LT guts to anyone)

amazing HP.com has your books, and is always there.
read them it specs it out.
yes, power packs go bad, 3 ways, dead, weak, or intermittent.
all do in time, (max life is about 20years,less if overloaded, as i bet you did)
if the PC needs, 50w, do not put in a 30w. use 50 or 75 or 100w
see? or it overheats .the pack,


here is your page (OP)
seems very very old, HP, is fighting me...
needs 19v at 90watts,
$8 to learn what is bad, is this too much>?
old XP LT built in the 1990 its very very old and slow.
256mb ram wow. Celeron ouch.

Compaq Presario needed a new battery was installed labtop will not charge up!


When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
