The battery is not charging


Turn the Acer notebook off by pressing the "Power" button. Remove any power sources connected to the notebook. If the notebook is open, close it.

Flip the Acer upside down and place it flat in front of you. Slide the battery locking mechanism to the right. The locking mechanism is diagonal to the lower left corner of the battery. While sliding the mechanism, slide the slimline battery out of the battery bay.

Insert the AC power adapter. The AC power adapter outlet is located toward the middle of the right side of the notebook. Attach the other end of the power adapter to a functioning electrical outlet. Open the laptop. Turn the power on. If the Acer notebook powers on, the AC power adapter is properly working. Replace the AC power adapter if the laptop does not turn on. Remove the AC power adapter and turn the notebook off.

Inspect the slimline battery. Look for signs of damage such as dents and corrosion. If the battery contacts appear to be dusty or have residue, gently clean them with an alcohol wipe or cotton swab dipped in rubbing alcohol.

Re-install the battery by sliding it back into the battery bay. You may hear a click or snap when the locking mechanism locks the battery firmly into place.

Plug the AC power adapter into the laptop. Leave the power adapter in the notebook for eight hours so the battery charges.

Remove the AC power adapter. Power on the Acer notebook. If the notebook does not power on, the slimline battery must be replaced. If it does turn on, the battery did charge.

I have a compaq Persario F700. When I plug it in and press the power button, the power button lights up like it is turning on, but the screen remains blank. Then the power button light turns off, and...

I can't solve your problem, but can tell you what I did to my F761us which has same problem as you are, it happened 3 weeks ago(08/2010) after we bought it-- 2 years 4 months the shortest life we ever have over 30 years computer experiences.

I am pretty sure my HD, battery, RAM, fan... are all OK
--the fan is working (you can feel it from vent)
I could see my battery light is on whenever I took it out for a while then put back, and after a whille the light off (should be fully charged).
we bought expansion RAM card, so we have 3, I did test all of them in each ram slot.
I also switch my power suply between HP L2000 and the broken one. I notice the broken one didn't warm up the power adpter-quite cold. but the same power supply plug into L2000 it warmed up as normal. does it mean something ?

we spent around $10 to convert internal HD to external usb HD
and could be accessed by our another HP DV7. (unfortunately we formatted it as C : D: 2 partitions, that L2000 can't accept 2 partitions.)

indeed the touchpad comparing my oldest still working HP L2000 (over 6 years), my F700 was very hot before it broken.

I did diassemblle it and found one shorty hair in FAN, and very very minor dust.

Battery light flashes orange three times then green. It doesn't impact battery life or operation. Is there a danger I that I might lose all my data? can I safely continue using laptop with ac adaptor...

This indicates either a faulty battery, charging circuit or motherboard issue with the charging port or charging circuit.

You can run the laptop solely on the ac adapter without issue as long as you have steady power. Try removing the battery and plug in the AC adapter and see if the laptop gives you the same light flashes...if it does, you maybe having an AC adapter issue. Try running the laptop solely on the battery and see how long the charge lasts.

Hopefully, all you are dealing with is a battery that is losing a few cells but is still capable of functioning...then you just have to get a new one.

It has been screwy since day 1 - power source issues, sometimes will turn on with AC & no battery. Other times.. I don't know if it's a button issue or power. Shouldn't you be able to turn this...

Most likely your power I/O board *(cant remember the real name) that connects to your motherboard (where you plug your ac adapter into) has gone bad or has a loose connection.

Message to change battery or connect AC

this means that your battery has very little remaining power. If you just charged the battery it means your battery is going bad. Replace the battery.

IPaq rx3115 working like PC not Pocket PC, need to plugin always

You need to purchase a new removable battery for your RX
The removable batts usually only last about a year (like cell phone batteries).
Although it is showing 100% charge, the battery is not storing enough power to run the ipaq

The rx series uses 2 batteries, one is the removable one u can see/access when u remove the back cover. The other batt is a small round batt which stores the basic info for your system (so you don't lose your data when u swap out the removable battery).

This small (backup) batt is similar to the cmos battery on a laptop or pc.
You cannot easily replace this, as the unit needs to be disassembled to access this batt.
If you are tech-y (and brave), the replacement button batteries are sold on ebay for $9-12

Normally, if your removable batt is bad, you could still use your unit plugged in, and could
remove from AC power without losing data. Not the case if your replaceable batt is exhausted.
When both batteries are bad, you lose everything when u remove unit from AC power.

My workaround without having to disassemble unit:
Purchase and fully charge new removable batt (They have huge capacity ones available for like $15 - better than the original !).
Load up all your programs & settings the way you like.
Perform full backup to SD card (& also on PC via active sync - to be safe)
Now the only time you should lose your data (like hard reset) is if you allow the battery
to completely drain, in which case you can restore your backup.
If you purchase 2 removable batts, you can easily swapout without losing data if you
use the usb charge cable & leave ipaq plugged in while you change battery

Hope this helps

ZD7000 Lights, no fans, power switch not working.............

Dismantled notebook thinking compressed air removed component or connection. Nothing. Reassembled most of notebook. Left battery and power disconnected for 6.5 hours, I later plugged only AC power into unit. Fans started spinning. Completed assemble of notebook and installed the battery. Blue lights returned. Problem seems to be the battery. Shorts out something and needs about 6 hours drain out. Works great now without battery, using AC power only. Ordered new battery.....

In Trouble can't power on my laptop with or without battery?????????

Sounds like the AC adapter cable has a break in it.

If you have a multimeter you can test it. I use a paperclip to get to the middle if my multimeter probes are too big for the hole.

If it's got good constant power then the jack on the machine where the AC adapter plugs in is probably loose or broken.
Sites like sells new jacks that you could get someone to solder onto your motherboard.
