Booting up issue


Does it do this with the mains charger connected or only on battery power?

The plugging in the mains charger if not already, wait a couple of minutes and then try switching it on.

If the boots up fine you more than likely have a battery problem.

If it still doesn't start then you either have a power supply problem on the laptop itself or your main charger is faulty and not charging the battery.

You can also remove the battery and try booting it with only the mains charger connect.

Please provide the results of these queries

Plug the USB drive into laptop
Press and Hold "Ctrl" & "Esc" keys.

Sit back and wait for your laptop to install the bios update.

My Acer Aspire 9805 battery was replaced. For


It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

My Acer extensa4420-5963 has been acting funky for the last three/four days. Started out my date and time went haywire. Clock kept losing time as soon as laptop was turned off and reverted to battery. Then...


Hi,

First of all the RTC (real time clock, BIOS/CMOS) battery has run out. This means the computer cannot keep the date and time when its turned off and disconnected from the mains. You will need to take the laptop to a reputable PC repair store and have them fit you a new CMOS battery.

As for the power on problem, this well could relate to the CMOS battery being drained but also could be a number of different reasons why it won't power on properly.

In my experience laptops that have problems powering on is either to do with the DC adapter on the laptop that has a dry solder point or the power board is failing.

Either way i would take the computer to be looked at.


Regards.

Acer extensa 5620 laptop will not boot uo


Then you can check 2 things to see if the machine will boot. If not, then you'll need to get it repaired. FYI, I repair Acers.

Step 1 - remove the battery and the A/C adapter from the back of the computer for about 2 minutes. Replace the battery and the adapter and try to start the machine. If that doesn't work, go to step 2.

Step 2 - Check that the A/C adapter is getting power and the LED for battery charging on the front of the computer lights. You can check the voltage from the power supply with a volt meter, if you have one -- it should read around 18-19 volts. If either of these steps don't work, you'll need to get it looked at.

Problems could be with the power supply, motherboard, power switch, CPU or something else that only time and expertise could properly track down.

Acer Aspire 1640 power problem


Will the unit work without the battery? The new Lithium Ion batteries can be overcharged and then cause all kinds of strange problems. Take the battery to a reputable electronics shop or Batteries Plus and have them run a voltage and current test. The current test being the most revealing. If either of these is higher than the level printed on the battery, dispose of it. Also, check ACER's web site for battery problems. All the computer manufacturers have had battery problems.

Good Luck

Acer laptop travemate wont even make any noise or boot up... why?


My initial thought would be that your battery will no longer hold a charge or that your power supply has gone bad. Try taking the battery out and booting the computer with JUST the charger. Any change? How about booting from the battery alone? Have you had any spills on or near it in the last 6 months? If it turns out to be a battery, you can buy them online for around $70. There seems to be an abundance of parts for this model acer. It definitely sounds power related though. If its not the battery or the power supply, my last guess would be the motherboard. Good luck and let me know if things change as your are testing it.

Power On / No Boot


Is it POSTing? Do parts make noise and then theres a Beep? The beep means it finished the Power On Self Test. Once it posts then it will show splash screen or black screen with it testing hard drives disk drives etc.. If no post is the led lit that says A/C is connected? before you attempt to turn on? If no post and good ac to rear connector then you probably need a new motherboard.

PC not booting


Assuming the power supply is good, sounds like the ac plug where you attach the ac adapter to the laptop has been unattached from the mother board.
What model is it?
