SOURCE: Power light flashing/ no picture

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

SOURCE: The laptop won't boot/turn on, no noise

Try this:

Remove all connectors, media and devices (cables, USB devices, floppies, CDs etc)

1. Press AND hold the power button for 10 seconds. Light should go out.

2. Remove battery.

3. Plug in PSU (the AC power supply unit)

4. Press power button.

5. If the laptop starts, go all the way to desktop and run the laptop for 20 minutes or so.

6. Shut down and remove PSU.

7. Re-attach PSU and then insert battery.

8. start laptop. If it starts, go all the way to desktop and use laptop for an hour or so, to monitor the battery state, see if it is charging. If it is, go to step 9. If not, test PSU and battery, to see which needs replacement.

9. Otherwise open START MENU/SETTINGS/CONTROL PANEL/POWER SETTINGS.

10. Uncheck HIBERNATION in the tab that applies.

11. Set all spin down, sleep/suspend and monitor settings to "never".

12. Apply/OK and Close Power CP

13. Now leave laptop on, let the laptop sit, idle (or use it) for at least 3 hours.

14. Shut down and remove PSU, then restart.

15. If the laptop will not start, or did not show a full charge before shutting down, replace the battery.

16. Go back and set spin down/suspend and monitor power settings to DEFAULT, but do not use hibernation any more on a 3 year old laptop!

SOURCE: CPU Upgrade

You pulled the processor out of your laptop ... that was a brave move ... generally laptop boards are fully integrated so there is very few options on changing the processor ... also because of the extreme heating conditions the heat sink bonding is very critical ... make sure you replace this properly or you will have overheating issues in the future ...

SOURCE: SATELLITE M35X-S329 sartup problem and freezes

I worked on one of these a few months back, it about drove me the nuthouse!!!!!!! after some long hours of going over every chip and connection in that laptop, and by now a couple more gray hairs, I started my search for help. It turns out there was a class action law suit for this product (not sure now on date) but I'm sure of the M35X. There is a issue with stress fractures in the motherboard, along with a couple of bad soldering connections on the board as well. This one I was working on was so strange it even started to boot as I had the HD half way out of the machine and no battery!!! Sounds like you need a new board, sorry! Just make sure if you do, get a good warranty and extend it!

Laptop wont boot up, black screen, has power


You didn't post the Make, Model of Laptop or the OS you are using. I'll use a Win 7 solution. Boot the Laptop, open the Control Panel, select Power Options, set to High Performance, select Change Plan Settings, set SLEEP to Never, select Change Advanced Power settings, go through the settings , set SLEEP and Hibernate to Never, Power buttons and Lid to shut down. Always shut down and unplug your laptop when not in use to prevent damage from power surges and possible Fire hazard IF the battery malfunctions. A reboot every day will reset the computer.

Charge


What? See my problem? The more info you provide the better the solution. Is it plugged in? Have you tried another cord/charger with the Exact same power specs? Is the battery dead? Will it boot on AC power?

Set dead


Hello,
Did you plug your AC adapter in and then try to turn it on? It may be that your battery ran out of power. Try to plug your AC adapter into your laptop, wait about 2 minutes for the battery to charge, then turn on your laptop. If that doesn't work, you may need to replace your battery. The battery on that laptop is fairly cheap, ranging in price from $10 used to $60 new. If that doesn't work, your power button may need to be fixed. You then need to have it fixed by a reputable computer repair store.

Hope that helps. Good luck!

Why is my acer emachine charging blinks in red


That is a signal that your battery is almost dead or drained. If you have the power cord plugged in and the battery is not charging at all, that means the battery is dead and you need to purchase another one.

In windows xp you should be able to click Start/Control Panel/Power Options. When the power options window opens click the Power Meter tab. It will tell you if your battery is charging.

Now to isolate if it's really the battery that's dead or if it's the Power Cord that's bad. You might really be operating on battery power even though you have the power cord plugged in.
1) Turn the laptop off and remove the battery. Turn it back on with only the power cord plugged in. If it comes and and boots up ok, then your power cord is ok.
2) Turn the laptop off and this time put the battery in, but leave the power cord off. Now hit the power button and see if it boots up. If it does that means you might have a little power still left in the battery, but since it was not charging when the power cord was plugged in, the battery is bad because you verified in step one that the power cord is good.

Hi, I've had my Acer aspire laptop for a few years now, but I haven't used it for over a year (Because I got a desktop). So when I've come to turn it on today, It won't work. The screen...


Start with pulling the battery and power, then hold the power button in for about 30-40 seconds. Then plug the power back in (still no battery). Try to power up the computer. If it boots, shut it down and put the battery in and try again. If it boots the issue was cleared. If it boots with the power cord but not with the battery added, you have a battery issue.

Hope this helps

I am unable to start my HP pavilion dz6700 laptop..it turns on and in a sec it switches off. Battery of laptop is dead and even though i connect to externa power source it doesn't start


Hi,

Unfortunately there's a problem with the motherboard of the laptop, you need to replace it. One of the circuits is grounded or is totally dead to accept and release power for the unit to turn on.

Hope this helps.

I have hp6735s dark screen problem even with external monitor


Try removing the battery and see if it starts. If the battery is dead, the laptop will be unresponsive as you described. If this doesn' work, then switch out the power adaptor. You can find these on eBay for less than twenty dollars. Your laptop is not getting adequate power to boot up.
