Hi forum, I have been using Compaq N610c notebook and was working fine but was not power ON . on AC adapter but it was working on Battery. From last day, the battery become zero showing battery indicator...


It's possible that the AC adapter "died", and then your computer ran on battery-power until the battery went to 0%.

Or, the socket on the laptop where the AC adapter connects could have broken, or become disconnected from the motherboard, such that the power from the AC adapter was not being accepted, meaning that your computer was running on battery-power.

Take the AC adapter and the computer to a qualified technician, who can test that the AC adapter is working fine, and can disassemble the laptop, to inspect that socket where it connects.

Motor started tapping loudly as if there was no oil, oil level was fine, changed oil sound quieted after 20 minutes, sound came back a couple of days later, went away the last couple of days on short...


hi this could be due to your hydraulic tappets, these will start to rattle if the oil has been low at some stage and the oil was to thin this normally sounds worse in the mornings on first start and gets quieter as the day goes on or disappears altogether, what you could do, is use an engine flush, put it in the engine and run it for a period of time, then empty the oil and refill with a thicker grade oil and see how that goes..hope this helps

At start up, before windows loads, a consistent series of annoying beeping occurs....


If they're occurring right as you turn the computer on, it's your Power On Self Test (aka POST) letting you know. Since I can't be more specific, here's a synopsis of POST beeps:

One single beep followed by three, four, or five beeps -- System-board problems, possibly with DMA, CMOS setup chip, timer, or system bus. The computer usually won't boot when this is the problem.

Two beeps -- The POST numeric code is displayed on the monitor, usually nothing to be concerned about, but you might google the code on another computer and see what you get.

Two beeps followed be three, four, or five beeps -- First 64K of RAM has errors. Solution is to replace RAM.

Three beeps followed by three, four, or five beeps -- Keyboard controller failed or video controller failed. Either you won't be able to see or type with this error.

Four beeps followed by three, four, or five beeps -- Problem with serial or parallel ports, system timer, or time of day. Check your BIOS settings (usually F2 at start up) to make sure everything is correct.

Continuous beeps - problem with power supply. Probably won't do much with this error. At the very best, your computer will boot and run very, very slowly.

Hope that helped.

Storm last night, now Wii won't power up


Unplug everything! There is a "breaker" in the power supply and it may need to be reset. Just unplug all cables from the TV and outlets. Let it sit for a couple hours then plug everything back in and it should work fine. If not then the power supply has shorted out due to a strong power surge. You can claim it under your home owners insurance or call Nintendo and try to get it replaced. Thanks! Good luck and happy gaming!!

AC Power and Battery Problem.....


Sounds like the battery or possibly the charging circits themselves are the problem. Can you try turning on the laptop with just the power cord in and no battery?
