My dell latitude c610 shuts down and the charger light goes off when i put my battery in


I think the AC adapter is shorting the motherboard. Try another AC adapter. If trying another AC adapter does the same thing, then have the motherboard checked.

Lenovo 3000 Notebooks : N100 Power Failure!


Hi.. I have a temporary solution to your problem. I had the same problem. Remove the battery and the ac adapter from the laptop. Just reconnect the ac adapter without the battery and switch on the lap. Presto.. Problem solved.. It doesnt power off anymore unless u remove the ac adaptor. Usefull if u hav needed files n want 2 create a backup. Still i havent found out a permanent solution to this problem. I suspect its a motherboard fault

I had to reboot my acer now my hard drive is almost full. How I make space for it. Also i have an error 1 in my mass control. Help I didn't now that acer laoptops had so much problems. I plug the cord and...


Backup you files and documents to DVD then reload Windows using the restore DVDs or CDs the notebook came with. This will solve your space issue as well as your mass storage controller error.

Also sounds like you may need a new AC adapter and battery, both should be faily easy and inexpensive to purchase on eBay. Just search by you Acer model number and both the AC adapter and battery should show up. I would at least get the AC adapter, sounds like there is a break in your cable. I got one for my wife's Acer for under $30.
