    presario c502us. noticed the battery losing power while the a/c adapter was plugged in. battery charge went to zero and now it wont boot up. removing the battery makes no difference. changing a/c adapter makes no difference.... although the charging symbol is on, sometimes flashing.



    I have this sickening feeling that the problem is internal.

    If I let it sit for 1/2 hour it can almost boot up

I hope trouble with your motherboard as far as your power supply is new and giving the accurate voltage.

The motherboard is controlling the switching device. Some short circut may be happening

decide what is faulty and replace it
otherwise a new mother board and cooling fan

new sshd ( sata ) better faster performance with no moving parts to fail

Samsung tv wont turn on


Check with Samsung first, most of their TVs and monitors come with a 3 year warranty and if you open the unit it will void the warranty.

Wii console got heated up and later on no power supply despite checking with neighbors power adapter. Brand new about 4 months old.Thanks for guidance in advance. ---pat_vv


If it's only 4 months old, call Nintendo Customer Support and explain that your Wii no longer powers on. It should still be under warranty and they'll send you a new Wii.

So, what is your question?

There is nobody on FIXYA that "officially" speaks for either HP or their COMPAQ subsidiary.

Buy the "three-year-extended-warranty" from HP before the "standard" warranty expires.

Review your "backup" strategy, to eliminate/minimize any "data" loss that you might experience when each laptop fails.

Most common reason for this would be defective power supply, if it is less than 1 year old, may still be under warranty. If older then you can usually find replacement power supply $40+ at local computer store. Not to difficult to replace, average tech could swap it in less than 15 minutes. Can test it with one of these: http://www.antec.com/Detail.bok?no=429
